Morning all...
Ok...99 GMC Savanna 5.7 seems the rear of the intake manifold is leaking coolant, and I think my exh might be getting some coolant in it also....
My question is will it harm my vehicle to leave the leak alone for a while,or should I break down and tear into it this weekend? someone told me that GMC's all leak from the intake manifold? Appreciate the advice in advance....
