I’ve looked around for a repair manual and could not find. Mine had the too common radiator hairline crack on the top plastic this past week. Ordered a new radiator and tried to replace it today. Could not get to the bottom bolt on the passenger side. I went in guns a blazin’, but the LC defeated me. Any ideas?

This is beautiful, thank you so much! I was thinking, surely I don’t have to take the bumper off. So I thought I had missed something. Looks like bumper has to come off. A little surprised by that, but now I know! Thanks again!!
Might as well replace it while you're at it! Cheers! :beer:

Just checked. Lower PS bolt is def accessible with bumper on. DS similar. I’m not sure if years other than my 13 are the same.

Gold bolt head to the left of the black painted one. 12mm with a bunch of extensions

Am contemplating replacing my radiator myself. How hard was it for a DIY'er, say on a 1-5 wrench scale? How long do you think it would take?

Thanks @Mogwai for the scans. I was surprised that in addition to the many steps to free the bumper, they would have you remove the air cleaner hose, vacuum hose, & No. 2 ventilation hose (step 11 in removal). I'm not in front of my LC, and haven't done this before, but I couldn't see the rationale for this. Aren't those things pretty far out of the way for removing the radiator? Doesn't appear that they get in the way of the fan etc. But what do I know.

It has been about a year but I think I did remove my intake elbow.. I’m guessing to get the resonator boxes totally clear of the fan and shroud coming out.

It is quite easy.. just don’t forget about the vacuum hoses on the back side of it when you put it all back together

Just changed out my radiator this weekend. I'll probably put more detail in the mega Radiator PSA thread, but wanted to put a word of caution here. YMMV, but I had a tougher time of it and ended up having to remove the bumper and the oil cooler to get it done. I'm no pro-mechanic, just consider myself mechanically inclined and able to follow directions (-: but in the end I couldn't get the passenger side mount off of the old radiator. Relied heavily on @Mogwai 's pictures but skipped a few steps. But it's done, no fluids gushed out when I started it, and it didn't overheat and seize, so it's a win.

My prior experience with cheap aluminum radiators in other vehicles is to avoid them at all costs.

The stock ones crack, in one specific spot that is easy to keep an eye on, but you get a lot of miles out of them before it happens, and that is the only problem with them. Plus the newer ones seem to be designed better specifically to address the problem.

Personally I’ll leep running OEM.

I purchased a 2010 LX570 a few months ago, and I have been doing a little investigating on what work that has been done, I'm guessing that this radiator is not the original?
