Good quality replacement radiator
This is a great replacement radiator. Installation in a 2009 Suburban was easy, and the fit was perfect. It works great, with no leaks. I've used Spectra brands in past with no issues. My only complaint: the radiator was shipped in it's factory box...low quality packaging. The inlet spout had actually punched through the box during transit, but fortunately there was no damage to the radiator.

Works perfectly and no leaks.
Had to replace a leaking radiator in my 05 Avalanche Z71 with only the trans cooler and was a very simple repair. New one fits perfectly and doesn’t leak. And as a bonus it arrived 3 days early.

Price was good.
Fit perfect, was half the price of all the local parts stores and I received it in 2 days. I would buy it again, looks just like the original one that came out.

Easy to Install
Easy to replace our GMC 1500 Sierra 2011 radiator. We had never done this before and with a few videos, it was an easy process. Cheapest price we could find for our work truck and great quality. Easy to install. No leakage. Working great!

2012 Suburban without EOC perfect fit
Installed in April. Perfect fit and as others said take rubber fittings from old one. Took it on first road trip about 300 miles one way with many mountain ups and downs. Worked fine and engine temp middle all the way. Transmission temp is about 10-15 higher than stock radiator as several have mentioned. Weather is 90's also, hot summer. That is why 4 stars only. Otherwise, no leaks till now, coolant level same as day of installation.

Very good quality radiator
Fit and matched factory radiator. Quality was better since it included a drain valve installed.

Cracked out of the box - junk
Absolute garbage. Didn’t even start the truck and it was leaking from the cracked tank. Not happy. So I do the job, it’s leaking as I fill it. So then I think the lower hose must be leaking. Replace the hoses. Still leaking. Now I’m a couple of $30/gallon bottles of dexcool in and it’s still leaking. So I poke around and find a crack in the tank! I’ll be about $120 in dexcool in by the time this is fixed. So wasted money, wasted time and now I need all new clips for everything from removing and reinstalling so many times. Super annoyed with this junk. Literally would have been better off jb welding the old one
