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?

Most of the time it is because the water pump is going out and it is leaking where the pulley is on the engine.

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.

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.

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 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.

No,the engine is designed to be no interference.You can turn the crank or cam without damage to get it in time.

Timing mark on the crankshaft pulley (mark should be at zero) must be aligned with the mark on the camshaft pulley (mark should be in the middle of the hole in the pulley).

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.

The crankshaft pulley is the lowest pulley on the engine. Looking at the engine from the front which is looking at it from the passenger side fender the crank pulley is on the bottom of the engine and has a pulley with a pulley behind it with teeth on it.

Open your hood and look at the front of your engine. There is a pulley connected to your power steering pump on the right side of your engine. It has hoses coming out of it. If you look below it your alternator should be there. It has a smaller pulley connected to it.

yes it is!! it must be froze up, the belt should turn this pulley to make the water pump work so coolant circulates in engine.

drain radiator of coolant, remove serpentine belt and remove pulley on water pump. If the pulley has 4 little bolts on it then loosen and pull the pulley off. If there are no bolts on the outside of the pulley then its pressed on, you can remove it yourself with a blowtorch but its hard to get off and on correctly. Remove the bolts holding the pump on and pry the pump off the engine, this will be hard most likely due to the gasket holding the pulley to the eingine. There will be coolant that will come out due to coolant you couldn't drain by the radiator...just have a container under car to catch coolant. Once removed scrape all the old gasket material off the engine... there is a gasket remover tool but a razor blade workls just fine. Once removed clean area well and apply gasket to new pump with gasket sealer and place pump back onto engine. Tighten bolts and replace pulley and belt, fill with coolant and top off as needed. be sure to purge the coolant systemof air after any major coolant work. The repair is relatively easy as loong as you have the right sockets for the job...good luck!

The 2002 Toyota Camry belt tensioner pulley can be loosened by loosening the pulley nut. The pulley nut is located in the center of the pulley.

More information would be helpful. Engine size, and if it looks like it's leaking from one pulley or several? My first thought is that the front seal is leaking around the crankshaft pulley. Other oil leak sources are the timing cover, the valve cover(s), or even a cracked cylinder head, could let oil trickle down and get slung around by the pulleys. What's the highest point of the engine that looks like oil is leaking around? Either way, it should be repaired.

The timing marks on a 1991 Toyota Tercel are on the crank pulley. They are located on the front of the pulley and under the cam.
