If it is the seal between the cover and the engine, drain the coolant, remove the hose from the housing on the engine cover, remove the screws/ bolts, scrape the old gasket, dry the area, apply rtv sealant to a new gasket and reassemble. If it is an o-ring leak, remove as specified, install new rings, and reinstall. If the pump is leaking, or the bearing is substantially worn, replace, and reassenble.
Replace water pump and gasket
YOU DON'T!!! I have a 2003 avalanche and I had to replace the water pump you can't replace the seals!!! It's a defect in the 2001 to 2003 avalanche the seals fail.
How do you replace the water pump on a 1988 Cadillac Seville?
no
the water pump is driven by the timing belt. highly recommended to replace the tensioner, tensioner and idler pullies, and cam seals.
if the water pump is bad most vehicles have a wheep hole as a sort of warning. if this is the case replace the water pump and any seals relating.
I just want to know when do i have to replace the water tank.
you can but its best to replace them and a water pump at the same time on some makes an modles
you have to take the timing belt cover off and timing belt to get to the water pump
You need a water pump and water pump gasket (sometimes it comes with water pump but not always). It's a good idea to get to replace crankshaft, camshaft and oil pump seals. Also if money allows replace the timing belt spring and its tensioneer.
Drain the radiator. Remove the drive belt. unbolt the pump and remove it. Replace the pump and the o ring that seals it.
it depends on who does it.
