It could be either, by far most are 3 bolt.
A foot valve, in relation to a water well, is a check valve at he bottom of a well to keep the water from running back into the well from the pump when the pump is not running. If the check valve does not hold the water the pump will lose it's prime and will not pump water.
I just installed a water pump on a 1997 Chevy Lumina and used Permatex Water Pump and Thermostat Housing RTV Silicone Gasket. Gel or paste in a .5 oz tube. Got it at ORilleys Auto Store. I don't like to install gaskets without something on them, just in case. I used a single edge razor blade to remove the old gasket material. You have to be careful not the damage the gasket face on the Engine water pump housing.
i don t know. how do u seal a water pump?
The first water pump was invented by the Mesopotamians in 3000B.C
The circ pump is used to circulate the water thru the filter. The booster pump is for running the pool sweeper.
There are three bolts. 10mm socket
inside the front of the engine, driven by the timing belt
it is possible your radiator is clogged
the fuel pump is in the gas tank
The 3.3 it runs off of the serpentine belt. The 3.5 it runs off of the timing belt.
If you are seeing coolant leak out of the hole next to the thermostat on a 2.7L, that is the water pump weep hole. You water pump needs replaced. The water pump is internal to the front of the engine, driven by the timing chain.
The factory installed pump would have been a bolt on. Most replacements have pressed on pulleys.
If you have a 3.5 liter motor, take it to an independent shop, I would not recommend it for d-i-y ers.
The torque of a water pump bolt can be requested from the manufacturer. The Chevy Trailblazer has a high torque for the water pump bolt.
the water pump is driven by the timing belt.
On the 3.5 intrepid engine, the water pump is run by the timing "belt"- no timing chain on this motor. Not sure about the 3.3 motor. On the 3.3L the water pump is driven by the serpentine belt.
there isn't one try changeing the relay
