Thread: Hot running temp for my 2004 GTP

I would second the radiator is probably blocked up. When i did my cam in march i flushed mine multiple times and you wouldn't believe some of the gunk that came out of it. That gm dexcool bs is a radiator killer. Flush it yourself, make sure it's full and burped then if it's still reading stupid start checking sensors.

I hope I can be of service to you in the future.

Happens dude. Glad you got it fixed. Summer is bad time to have cooling issues.
