If it is a 6 cyl, it is attached to the fan, it is the part mounted to the engine that has the shaft sticking out that the fan mounts to, if you think it is defective replacing it takes about 3 hrs, you may have to take the radiator out depending on space, I don't remember, either way take the fan off first, set the fan aside, lay it with the front of the fan down, the side that normally faces the road ahead, it is important to keep it like that.

There are a couple of bolts, you may have to tap the part lose, use a piece of wood and a hammer, don't try to pry it with a screwdriver or wedge, it will pull forward a few inches so be sure of your room if the radiator is still in, clean away the old gasket, pop on new part with silicone rubbed gasket, put the rest back together. You will be dumping a bunch of coolant on the floor, be ready for that.

The only question I have is do you know the pump is bad? Not questioning you just asking if you checked out why it is overheating..if it points to the pump, the reply is correct.

Water pump how it works


Well, it pumps water through the engine pulling the heat out of the engine and getting rid of the heat through the radiator.

Water pump is boiling on a 1999 CADILLAC DEVILLE but car drives okay vibrates a little


water pumps do not boil but engine coolant systems do from lack of water . Water pumps leak and get bad bearings but the heat comes from blocked radiators-blown head gaskets--cracked heads --fans not working and the vibration is from pistons and rings trying to bind up in the cylinders from over heat situation

Over heating , antifreeze leeking from that water


Hello,

If your water pump is leaking from the water pump for sure that is causing your over heating problem. I am sure that most likely the seal is gone. There is a main seal in the pump, and those are normally the first to go, and you are better off replacing the whole pump, that trying to fix it. Once your water pump is replaced , the over heating problem should be fixed. If pump is leaking it does not have the pressure provided to have the antifreeze and water to flow correctly through engine block and radiator.

Thanks Mike

Slow Leak in Water Pump-1999 Plymouth Voyager


What's probably happening is the weep hole on the water pump is leaking water. The weep hole is a warning sign that the water pump needs replaced. You don't have any heat because the impeller in the water pump is no longer circulating water.

Can a bad water pump cause other things to not work properly? like the heat? and will it over heat?


Yes That is exaxtly what will happen, If the water pump is not pumping the antifreeze throught the system then not enough hot water will get to the heater core to give you heat inside the cabin and also not enough hot water will get to the radiator to get cooled off thus the overheating. Hope this helps.

I have water leaking from the engine, but don't know where from. The radiator has been changed the water tested for emmissions, pressure tested and still water is leaking. The heating blows hot when...


if you see the water leaking form the front side of the engine usually from the water pump since the pump is not running you also wont get heat, bit when you pressurise the sys you are forcing the hot water into the core and you have heat, it is the water pump.
