Only when they are bad.
Do you have an oil cooler? I have heard that is a possible cause, as would be the head gaskets.
head gaskets gone.
These engines do not blow head gaskets. You need to replace the black plastic intake or plenum. They will leak coolant into the combustion chamber. Some roge mechanics will tell you it's head gaskets to get you to pay more money. Remove upper intake, remove spark plugs to get coolant out and replace and fill with coolant.
Yes, this is normally caused by a blown head gasket cracked or warped head or both. The intake manifold gaskets go bad and leak coolant also. The original Chevrolet stock intake gaskets were not so good.
Not necessarily have system pressure tested to determine the source of the leak
intake gaskets are between the head and intake. head gaskets are between the head and the block..
what is the preceger for replacing the head gaskets on a 1993 chevy suburban 4x4 350
coolant no were near the oil pump/pan. because if mix that it will stuff up your radioator and blow your engine up. radiotors arent CHEAP!!!!!!!!!!!!!! Coolant won't get in oil pan froma water pump but it can from bad intake gaskets, head gaskets or a cracked head.
Can be leaking intake manifold gaskets, which can sometimes be fixed by using Dexcool coolant. Can also be a head gasket.
not to be rude but if you are asking how to do this dont even attempt it! if you get coolant on any of the internals by not completely removing the old gasket or over torquing you will throw a rod........ i will just tell u this.....scrape well, very well. if you know what you are doing. and if you dont know where the head gaskets are....take off the intake maifold.... 1993 fleetwood brougham......d-body yes but i don't have alot of money and i need my head gaskets replaced so how i do it.
The Northstar is a good motor, but they do blow head gaskets some times. If the coolant is going above about 230 degrees, or if you are having problems keeping the coolant filled, it sounds like you need head gaskets. The problem is caused by old coolant corroding the head bolt threads out of the block, and the head bolts pull out, releasing the clamping force on the gaskets.Have a garage check the coolant for exhaust gas - this is the best way to diagnose the problem.
Besides the head gasket and head bolts, any other gaskets, hoses, belts and coolant damaged or lost during the process.
