water pump .(gasket,intake,hose)
Sounds like water pump needs replacing The main pulley is near the top of the engine. The water pump is toward the front of the engine. It is possible that water appears to be leaking from this pulley, but there is a manifold gasket right above it. Double check to find exactly where the water is exiting the engine block. My first hunch is a leaking gasket.
Leaking? Pulley loose? Noisy? No coolant circulation?
There is a weep hole at the bottom just under the pulley where there will be a stain of coolant if it is leaking. Or unhook the belt and check the play of the shaft of the water pump.
The bearings can get noisy and you may see the water pump pulley and fan wobble when the engine is running and of course the obvious would be coolant leaking out the weep hole in the water pump.
Most of the time it is because the water pump is going out and it is leaking where the pulley is on the engine.
If you can move the pulley from side to side, is noisy, or it is leaking it is defective. Remove the radiator cap and with the radiator full enough to see the coolant, start the engine. If after the engine reaches operating temp, you do not see flow of coolant within the radiator the pump is defective.
The timing marks, on your 1992 Toyota, are located on the main engine pulley. The timing marks can be found around the perimeter of the pulley.
The 1990 Toyota Camry timing marks can be found on the main pulley on the front of the engine. The timing marks will be scattered around the outside of the pulley.
The water pump uses the timing belt to spin the pulley on it. The pulley than propels the coolant throughout the engine. This keeps the cars engine at a moderate temperature.
I need a video or diagram on How to remove a crankshaft pulley from a V6 4.0L jeepit looks like my coolant is leaking because the seal needs replaced. Have you ever or is there something I'm missing
No,the engine is designed to be no interference.You can turn the crank or cam without damage to get it in time.
There are several areas coolant can leak from. If by "under the body" you mean you see it is under the car but not necessarily right under the engine it could be leaking from a component on the engine then running down the frame before it drops to the ground. Common area for leaks is the water pump. There is a "weep hole" at the bottom of the pump behind the pulley.
