My problems with what he was doing basically boil down to recklessness, but let me explain further:

REMOVAL: Rather than drain the radiator using the petcock with the car on the ground, he raises the car and removes the lower radiator hose letting the coolant fall 6 feet into the drain pan and making a mess on the floor. To remove the radiator (made of aluminum and plastic), he literally tried to pry it out with a 3 foot steel pry bar. And, it wasn't working. One would think that at some point he would realize, "Hey, I can't move this radiator with my 3-ft pry bar so maybe I should take a step back and see what I'm missing?" But, he just kept plowing on. In the process of all that prying, he broke both of the plastic brackets on each side of the condenser that fastens it to the radiator and who knows what else that isn't shown. You can also see visible damage to the condenser being done and when he finally got the old radiator out it was absolutely mangled and then he goes on to complain about the mess of coolant and WD40 (that he made) that's all over the core support that needs to be cleaned up. But, rather than lifting the car and wiping it down with a rag from underneath (there's enough space), he drops a rag down to the bottom and uses his 3-ft pry bar (his favorite tool?) to push the rag around. The pry bar periodically slips and knocks into the condenser. The customer probably came back a month later complaining his A/C isn't blowing hot any more with the end result being a leaking condenser diagnosis--Gee, I wonder how that could have happened?

INSTALLATION: While re-insalling the new radiator the hood latch assembly kept getting in the way (and damaging the cooling fins on the brand new radiator), but rather than tying it back with some bungee cord he keeps plowing along. At one point, he is banging his fist on the top of the radiator trying to force it in. In the end, the video never shows the radiator actually going in to it's properly seated position--it just cuts to when everything is back together. Although he tries to "explain" what he did--yeah, right. He probably used the same pry bar to shoe horn the new radiator in, but didn't want it shown on camera for all to see what he broke. The whole time he's cursing at Nissan.

The trouble this tech went through can be traced to him not being familiar with the car and not reviewing service data (...or if he did, ignoring it to cut a corner and save time, which in the end he didn't). The proper procedure for radiator replacement in the 2nd generation Murano is to evacuate the A/C system and remove the condenser first. I can understand why a DIYer might skip this for lack of proper equipment, but there's no excuse for a professional as he surely has an A/C machine in the shop. Sure, it may add time to the job, but that's time the customer should pay for if it's required to properly do the job (...it likely is already built into the book time). And, he could have maximized that time by doing other things while evacuating the system (e.g. draining the radiator and removing the grille) and likewise while recharging the system (e.g. bleed the cooling system since the engine needs to be running anyway).

When the tech was moving the radiator in the video you can see the condenser moving with it in lock-step. That's because the condenser itself is fastened to the radiator via the two plastic brackets on each side at the top (which he removed--broken) and also two plastic hook clips on the bottom where prongs on the sides of the condenser seat (see pics below). I don't think he realized there were bottom clips that were keeping the radiator from being pulled up since pulling up on the radiator also pulls up on the condenser and since the refrigerant piping of the condenser was still intact the radiator core support was holding everything down. My guess is all the prying eventually broke the plastic clips and he was finally able to pull it out. He should have pulled the condenser up off the clips and forward and then the radiator should come out "easier." He would still have to deal with the clips catching onto the back of the condenser. There are some other videos out there that talk about the clips and also how to remove the plastic brackets without breaking them. People have successfully replaced the radiator with condenser still in the car without the butchery in this video. Those that also removed the bumper to get the horn brackets out had an easier time of it because it gives you an extra 2 inches to work with.

If anyone wants to grill me for Monday-morning quarterbacking when I don't wrench for a living that's fine. But sorry, I expect better from those that do get paid to wrench for a living.

I like what you said there, grill you on a Monday morning. I guess I see your point there and meant no offense. He probably did have an ac machine too. Ill admit that I dont think I checked the manual before performing the work when I did it either but I see thats not the point of what you mean. Had he done so, he would have seen that the condensor at ac system would need to be evacuated to remove the radiator properly and without a prybar lol. All good points! I wish I had one of those ac machines myself. I even saw a local auction house had a used one up and didn't go for it. I should have because it sold for $10. Couldn't believe it!

The hack finallly detaches the radiator's top hose connector w/cap and looks at the broken neck that's been mangled by his haphazard, insane prying and says... "It's all rotten!" I'm sure he replaced it with a new one and charged the customer by stating "it was all rotten and needed to be replaced" instead of eating the cost due to his carelessness. I've never seen plastic rot... When you jab at it and pry against it with metal tools, it will typically collapse and/or break. I haven't watched beyond this. What a mess.

EDIT: Holy hell! Sir Pries! Sir Pries! Sir Pries! I can't imagine the unseen damage Sir Pries-A-Lot caused during this job. Even prying against the headlight lenses... I see many of the plastic cover fasteners were put in the wrong holes...

Yeah, him trying to visually demonstrate with his hands how he gently manuevered the new radiator into place was comic gold. I'm sure the actual footage with a prybar, sledgehammer and accompanying profanity was too graphic for Youtube... I'm sure he did a top-notch reinstallation.

The plastic wasn't rotten, it was jabbed and pryed against with various metal tools which snapped the plastic... I haven't watched beyond this. What a mess.
But he sprayed wd40 on it, its good! Lol
Silicon spray works wonders, I like using it to put the hose back on esp. Yeah he really should have just pulled the after twisting that end loose with pliers.

I was actually very surprised he didn't spray WD-40 along the bottom corners and sides of the new radiator to help it slide into place. It probably would've helped.

The one positive thing I'll say about his video is, at least he made an attempt to clean up that coolant/WD-40 mess before installing the new radiator.

Since he carelessly showed the license plate of the car, I'd love to track down the car owner and see if there were any other problems with the car later on. And also find out what else the owner may have been charged for that was "discovered" broken or rotten as a result of heat. :)

Yeah I guess I presented a not so good example video of how difficult it can be to work under the hood on these lol. To be fair, I remember when I did mine, the radiator nozzle for the hose up there was rotted as well and I did not pry on it or anything like in the video. It is plastic and for the same reasons he sprayed wd40 all over the place, he should have taken more care there. My main point in posting the video was just to show how ridiculous it can be to work under the hood on this murano. Im not looking for it to be necessarily easy but it sure would be nice if it was "easier". In all honesty you shouldn't have to evacuate the ac to change out a radiator with confidence. How about they just give me the two inches I need, for free.

Yes, I agree. I don't understand why they couldn't have given a little more room to work. The nose of my 3rd Gen seems to have a lot of empty space that could have been better utlilized. Even trying to look at the the serp belt to check for tension is a PITA on this car. I'm not looking forward to the day I have to replace the radiator or alternator.

I've never seen plastic rot. I've seen plastic melt or become brittle, but never anything rotted or soft to the point it would collapse. Bad composite material?

I guess rot isn't the right term. Probably just brittle. The coolant did seem to leave a film or sort of a cholesterol looking substance/dust in that area which may have affected it even more. Idk

Yeah but this is the typical auto mechanics we have now. Flat rate ya know. Yeah I wouldn't want him near anything I own either. As I watched it I'm thinking he is probably doing it as good as a dealer tech would, or any other rush rush tech. Going slow and doing things right is not what any of them do, even the so called good ones on youtube. Most all mechanics are hammer and chisel, pry bar specialists.
Then they take out the roloc sanding disks to gouge up the gasket surfaces to remove all the old RTV. They can't waste time to do things right, that costs them money. Besides no big deal if a part or 2 gets ruined, it just gets billed to the job, and makes everyone, except the one paying the bill happy. Commission on parts sales ya know.
Yeah the WD40 on the hoses was a bit too much, that won't help the process.

That's a good one - WD40 on hoses is a joke. It does absolutely nothing other than making them messy to handle.

The only thing I ever use it for is the specific function it was designed for: to displace moisture. That's it. And since cars don't have distributors any longer, it's of no use to chase moisture out of a distributor cap. I don't think I have used WD-40 on a vehicle in 30 years. Silicone spray and lithium grease, yes. Not WD-40.

Is it just coincidence that the grille clip on the outer driver-side area is snapped off? The side he was prying and tugging at that suddenly "let go" and the grille came off? Also looks like center snap-tab is broken. I hate how he frantically waves around metal tools very close to painted surfaces.

This video by a DIYer shows a good strategy for replacing the 2nd generation radiator without evacuating the A/C system. He takes the bumper off and that frees up quite a bit of space making the job much easier. Also, you actually see him remove the old radiator and install the new one, at no time does a pry bar (or WD40) make an appearance, there's no cursing at Nissan, and he doesn't break anything. He could work on his videography though.

Why don't people ever place a piece of cardboard in front of the condenser to protect it from being scratched? It's such an easy thing to do to deter the fins from becoming damaged. The guy in the latest video contacts the condenser a number of times while removing things, and you can see how scraped up the front is. A better process, though. I like that he removed the latching mech prior to installing the new radiator, as opposed to Pryman's method of struggling with it as it got in the way all the time. I also liked that he removed the battery. While watching the first video, I was thinking I'd remove the battery to gain some elbow room.

I have learned in my years of wrenching, to take stuff out of the way even though it adds more work it is worth it. Also I have learned the shop manual is not always correct how to remove something, or do a particular task. The shop manual says to get the transmission out that the whole engine transmission unit has to come out. NOPE not true.

The mindset of some people is that they're saving time by not removing something, when in fact they often spend more time having to deal with a lack of access or the something constantly getting in their way. Beyond creating easier access and helping to prevent damage, you also save your sanity by eliminating situations where you might struggle with something and bust your knuckles and start swearing, making the job seem twice as difficult and twice as frustrating.

I think the metal cowl beneath the windshield on the 1st Gen is a perfect example. It takes all of four minutes to remove to give you tremendous access to the firewall-side of the engine, yet I see many videos where people leave it on while changing coils, plugs, etc, and they're struggling to get at things by feel in that confined space. Naturally, they seldom show the entire video of how they did things (the will describe to us how easy it was...) and will proudly proclaim they did the repair without having to remove the cowl and plastic covers, but they won't reveal that it took an extra 30 frustrating minutes to do it that way, and they won't say the number of times they dropped their tools under there and had to spend time retrieving them, etc.

You can tell the guy in the the first video was becoming very agitated with the radiator, even when simply trying to remove hose clamps. The more pissed off you get while doing the job the more likely you are to create damage to the car or yourself.

Over time, I have learned to be much more patient and take my time thinking about how I'm going to do a procedure. Being methodical usually generates better results and less frustration.

I seem to spend a lot of time looking for a part that I dropped... It never ceases to amaze me how quickly something can seem to disappear...
It's also amazing how consistently parts roll to the hardest spot to reach under the car - if they fall all the way through.
