Fits 2008 Avalanche with 5.3
Quality thermostat from a long trusted brand. Fit and works perfectly in my 08 Avalanche with 5.3 liter engine. I did a complete coolant flush and replaced the hoses and thermostat with Gates parts and I've been running at perfect temp for many months now.

Autozone junk vs Gates A+
Do NOT buy the autozone and local parts store bs. Buy this and your problems will be fixed. Installed in a Escalade. Was having over heating issues when I was stopped or going up hill install autozone ones and they would work great for a couple weeks then same problem again. I ordered this one as it was same day delivery while I waited for the OEM one from the dealership and honestly I don’t think I’m going to swap it out it’s doing great so far. So buy it and your problems will won’t be disappointed.
