Review: 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.
Review: 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.
