    Default 99 yukon 4dr

    my bro is selling me his yukon for cheap, and i was wondering whats wrong with it lol. i love the truck to death, its very clean but has a coolant problem. it doesnt leak what so ever but after some drive u check radiator and the coolant is low, where is it going if its not hitting the ground? head gasket? and right now it has a ravin muffler (meineke special) and was wondering how magnaflow would sound on it. i dont like the flowmaster sound, its too common. i have magnaflow on my 2.2 and it sounds great, very deep

    These things are prone to have the intake manifold gasket leak. It can leak out or in. If it has not already been replaced, I would suspect that. It's not too difficult of a job.

    well my brother said he put that stop a leak stuff in so im assuming its maybe just the radiator, might not be anything major, but im taking it to work tomorrow so i will see whats up with it. my friend is gonna check it over on the lift. i know it needs something for brakes, cuz they are soft when u press it but still stops on a dime
