Could the water pump put air into the cooling system of a 1998 Chevy venture?
uhm if the water pump is putting air in youre coolant system
then youre water pumps seals are gone the same thing happen to my
1996 Honda accord i took it out and found out the seals were gone
so the breather for it was sucking in air and letting it all in the
cooling system so id change it
It's possible, but if it happened there wouldn't be much and it
wouldn't really be under pressure. Also, if that's going on you'll
loose coolant when the engine is first turned off.
If you are blowing out coolant because of pressurized "air",
it's most typically a blown headgasket and you're getting exhaust
gas into the coolant chamber.
