Coolant leak in my 2000 Ford Taurus

have a compression test done as the bubbles suggest a blown head gasket or cracks. That will account for the overheating. The oil leak may be from the head gasket or cracks.

Well depending on what engine is in this vehicle, it could possibly be the water pump that is leaking or possibly a "freeze out" plug on the block. I would say it is more than likely the water pump. If you have no noticeable leaks from any of the hoses or radiator, i would definitely suspect the water pump or possibly the thermostat housing may have cracked and started to leak. My suggestion would be to look at all your hoses carefullly and then check the housings where the hoses connect to the engine block, if no signs of coolant are present, check around the water pump for noticeable coolant leaks. Hope this helps in your search for that coolant leak.

No!!!!...Yes!!!
No, the sending unit is working right.
Ideas? Yes, I think the problem is the water pump. Don't drive it overheated till you get a new water pump or have it inspected. You say it's a small leak where it bolts to block, but maybe it's the "weep hole" on bottom of pump leaking, meaning the internal seals on the pump have failed. If so, it won't be a small leak, it will leak all the time engine is running. A lot may be swept away by air, or by evaporating. Check it out. That's a likely cause of overheating.

I would pressure test your cooling system which would cause any otherwise unnoticeable pinhole leaks to spray a small mist of coolant if there was in fact a leak present. I had a similar problem with my wife's dodge caravan, I kept smelling coolant after she drove the vehicle for long periods and I checked the entire cooling system and inside vehicle for a potential heater core rupture and nothing was ever seen and coolant level always remained full. A couple days later I noticed the same thing and allowed the vehicle to cool down, I then pressure tested it at 16 lbs, I did not notice a drop in the guage but then I noticed 1 small drop of coolant coming from the water neck where I had replaced the thermostat several months back. I torqued the bolts down a little more rinsed off the area and have not noticed the smell anymore. That 1 drop of coolant would immediately evaporate once it hit the block but the smell was strong enough to get my attention and to figure out what was going on

some 3.0 engines hive a head gasket leak on the rear head on the corner hear the water pump..

This is either an air lock or a leaking headgasket. Remove the rad cap, with the rad full, watch for air bubbles. You didn't tell us if you were adding coolant??

A few reasons why ...Belt is slipping or broke... bad thermostat....faulty water pump ......low coolant or water... hose leaking... radiator clogged.. fan not working. Just a few to get you looking.

Your auto is definitely loosing coolant and will overheat. Check your thermostat, hoses, belts, radiator cap and water pump. If you do not fix the leak or coolant circulation problem you can destroy your engine. The smell inside can be being picked up from the outside vent or it could be your heater core inside the ventillation area leaking (which could be your coolant leak).. If that is the case you will need to replace the heater core.

Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.

The smoke must come from a coolant leak close to the radiator, or a fin crack in the radiator itself. Check all hoses and clamps, idle hot and look for smoke. You may have a heater core corrosion issue, watch close for coolant leaks on the floor mats inside, all of this may be connected and look for leaks where you park. Just a small amount can produce smoke, open the hood when it smokes and look.
