Asked by for the 2003 Chevrolet Venture
Hello , i am asssuming that the engine is a 3.1 litre engine .. The best oil to use is giong to be 10w30.. these engines are notorious for the lower intake manifolds to leak coolant , if it is leaking it needs to be replaced along with the oil change.. If the vehichle has dex cool coolant in it, replace it with the normal green coolant or a universal type coolant ,, dex cool eats up gaskets, and creates many other problems
ur saying dont use dexcool? just normal antifreeze? correct, and thank you for ur response
yes, do not use dex-cool, use regular anti freeze!!!!
