That sounds like the oil-pump seal (mechanical seal) has blown
You will need to drain the coolant, remove the oil pump cover, remove impeller & then seal

Can a bad timing chain cover gasket cause a coolant leak in my 2003 ford taurus


Yes the timing cover gasket can leak coolant. The coolant passes the waterpump and is pump into the engine block thru the timing cover. to see the actual leak jack up passenger side of car support with jack stand take off wheel and the splash guard now you can see the crank shaft pulley look up at waterpump on both side it goes back to engine block with a mirror you can see it leak.

My 2001 Pontiac montana is leaking coolant when it cool of. Its dripping from the transmition passenger side. I croled underneath and found that the coolant is leaking from the pass side of the engine...


probably a gasket that seals coolant behind cover. I don't remember if there is a freeze plug there.
sometimes a head gasket leak can do the same but not very common.

Why is water dripping from behind the timing cover?


Sounds like your water pump is just starting to leak. Are you sure its water and not coolant. Seem funny But make sure your car just doesn't have water in it instead of coolant. put a white piece of paper under it and let it drip on it to determine the color. Not terribly hard job to do but if your fairly new to repairs might get some help with it.

Keeps turning on and off and the timer light is blinking so it doesn't even turn on fully.


Usually when I see this set with an unusual problem the first thing I do is to remove the front cover and look for coolant leaking onto the circuit board. The coolant is in a small chamber above each picture tube and sometimes the gaskets lose their seal and it begins to drip down onto the circuitry. Get a powerful light and inspect it closely for a few drips coming from the frame around the picture tubes and look for small puddles of goop on the boards. The only other common problem I run into on this set is convergence issues which usually cause a dead set or color alignment problems when set is on. I really think whoever looks will find coolant leaks. Good Luck, Russmann.

2002 dodge caravan leaking coolant looks like from under engine


There are no coolant lines etc running on the lower part of the engine. Usually water will leak from above and run down finally dripping from under the engine. Coolant will not leak from the "engine" it leaks from a hose or thermostat housing.

Start from the top and work down. Check each hose by feeling with your hand. Look for a wet spot. wipe the hosed with a cloth to clean if necessary. If you think you found it dry the area and check again. Sometimes you need to move the hose around to open a small tear and expose the leak source.

If a hose leak tighten the clamp. If torn hose you may be able to disconnect, cut the end and reattach. If too short replace.

Check where each hose connects to the engine. This will be the thermostat housing and the heater supply line. If a housing try gently tightening (careful they crack). Or replace the gasket.

If you don't see a leak at all. Start the engine and run. This will build pressure in the cooling system. Look for leak using the same process. Careful as the engine is hot.

When heater is on i smell coolant


Hi

This is caused by a leak in either the heater core itself or the hoses connecting to the heater core.

Rust and corrosion can clog the tiny passages in your heater core. Sometimes the block becomes so severe that pressure builds up in the heater core causing it to spring a leak of coolant - enough to give off the smell you describe.

You can find examples of the heater core at this link

Solution: Replace heater core or hoses depending on what you find.

Hope this helps. Please do rate this answer. Many Thanks.

Antifreeze leak


check the 2 large hoses that come from the radiator, at the radiator and at the engine. if not there then your losing water into your engine, probably means your head gasket is cracked and about to blow
