Radiator crapped out.

[915_Tahoe]

Ugh. Everything seems to be breaking lately. Noticed antifreeze leaking and then the "service airbag" message pops up.

Radiator finally gave out.

Upper right side of the radiator I noticed these cracks.

Would anyone happen to know what size radiator I need for an '05 Z71? I tried measuring it without taking everything apart and I think it's 34" wide x 1-1/4 thick. Not sure of the height. The last 8 of my VIN is: 5R208540

Vin# is showing 2 sizes for your truck. If you can get the 3 digit code # off the radiator and cross the ones i posted so you can get the correct one.

Love my 3.73's. My GN has 3.42's--actually all turbo Regals came with them.

I did love my 3.73 gears in the other rig but this is more of a cruiser and I need to make sure, at 68 years old, that I don't get a ticket for making a crazy decision to race or haul ass when I should not be. I still drive 'em like I stole 'em but I also have my limitations. The new upgrades have made this 05 drive like a brand new rig. Beside, after the recent work with the motor mounts and removing the exhaust manifolds and breaking or finding broke, 3 end bolts and having to use the Dorman clamps, which work flawlessly by the way, I know that eventually I will do head work and throw even more money at my rig.

Do your 3.42 gears take you to almost 90 in second. This always made me laugh in my Envoy.

those radiators are not different sizes, they are identical size.

 

[OR VietVet]

Can't say. I have yet to drive it as hard as my 02. If and when I do that, which will likely be right after my next go round of upgrades, with the new throttle body and the new injectors.

Sorry, ment to say different options

I noticed the same size too, at RA, but I actually had an RPO code or two that matched for the 21647 radiator at RA.

ya it's usually oc or no oc, GM likes to change parts numbers at the drop of a hat, just a money game you can grab a used radiator out out of a 2014 and throw it in your 00 or vica-versa

Stupid auto correct made it abs instead of srs. Iirc, my scanner(innova) stated which side was bad.
@partcheck if you ever come down to Keansburg, I'm 1 mile away from the boardwalk. I could throw my scanner on for you.
@PNW VietVet I thought you had wanted 3.42's when you were originally looking, instead of 3.73's.

I have no plans on towing anything so 3.42 is fine for me.

I should have come here a month earlier. Wife and I took the kids down to Keansburg amusement 2 weeks ago for the whole day.

I'm basically down the block(s) around the corner.
