Having problems with your 1999 GMC Jimmy ?
I have a 1999 jimmy with 115,000 miles and I,m hearing about the intake manifolds leaking antifreeze what concerns should i have with my jimmy and what type of antifreeze should I be using
A leaking manifold could cost you a VERY expensive repair. I recommend getting it fixed as soon as you can. And with the antifreeze...seeing how it it a GM it should take DEX-COOL. But look under the hood and look for a white sticker and it should say "This vehicle takes DEX-COOL coolant. Do not mix with any other coolant" and if not the cap for the coolant should say so. If so, then obviously you need DEX-COOL or universal coolant. Universal will not harm anything, but I would use the manufacters reccommendations just on the safe side.
Check the ends/corners of the intake manifold, they are also bad about the fuel pressure regulators leaking, and the plastic fuel lines under the intake leaking fuel. Dexcool is the coolant used.
