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!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.
