I'm losing coolant at a pretty fast rate. Seems

Probably the water pump. You should see coolant coming from the vent hole on the pump--usually on the bottom.

I assume it's the 3.8 V6? They are notorious for intake gasket problems. The fan problem could be a few things, fuse, relay, ECT (electronic coolant temp sensor), ECM, Do the fans come on when you run the A/C? Hope this gives you some ideas. Let me know a little more and I'll try to help. TJ

This is a coolant tube that goes to the top of the water pump, it is called the upper water pump bypass tube, you will also need to purchase the rubber o-ring

When replacing, make sure you are doing a coolant flush, as old cooland will cause this type of corrosion and failure

good luck

Have a pressure test run on the cooling system, then raise the car up and home in on the coolant leak location.

there is a drain plug on the bottom of the radiator, it is at one end or the other-turn it counter clockwise to drain antifreeze, sometimes you have to remove a plastic airdam/shield to see/get to it. An easy way is just cut the hose off-you are going to put a new one on anyway, and you won't lose more than a gallon of antifreeze although if you are fast (you pretty much have to be draining a radiator) you can get a pan underneath and catch a lot of it-I still would just replace it with fresh 50/50 antifreeze, it will take less than 2 gallons to refil. Remember to do this when the engine is cold.

what is happening, is your starting to get a leak in your heater cord or the hoses that attach to it. it's allowing a small amount of coolant to leak out. check the passenger side of the car in the front just under the dash to see if it is damp. your heater core is behind the plastic wall under the dash. the vent right there is taking that smell of the coolant through the vents.

you can try the stop leak potions at auto zone

1)yes steam will come out of the resevoir,especially with a bad rad'cap.
2)thermostats are cheap.
does your cooling fan come on?,it may be a bad sensor or relay (for fan)
3)no heat in car!?,the water pump may be bad.or the heater core is plugged,or if you have:a bad coolant valve for cab heat.(but this wont cause motor-over heating issues!)
4)you have a plugged radiator!

--sounds like a bad waterpump to me.
even if it doesnt leak,the impellers still come loose from the shaft!!

Sounds like maybe a freezeplug...definitely have to go to shop if that is the case.
