Hello everyone,
I'm trying to help someone that has an overheating issue with his GMC. (I believe it's a 455 and I will confirm as I've gotten since last night.)
Every time they use it up mountains going to higher altitudes it overheats badly.
(FYI - I'm a retired ASE and US Army mechanic and I DON'T want him to just throw parts at it.)
My hope is that other GMC owners have experienced this with their coach and that there are some proven upgrades he can do; as I want to make sure that he does the right and best upgrades to his cooling system and NOT simply for him to replace parts until it is finally fixed.
Your help is appreciated.
Sincerely, Tony
