I have been noticing a little coolant puddle under my truck for a liitle while. It seems to be dripping in the pass. side front corner coming straight down from the AC compressor. I haven't been able to find the leak but I do have to fill the ovreflow tank every now and again. Someone told me it is probably the waterpump. Is this true or is it somrthing else? How hard is it to change the water pump? I have to do something about this. Thanks

 

the lower hose connection on the radiator has been known to crack. at least it did on mine... although a rad problem may be a little more forward.

 

The water pump is not bad. Drain the coolant, take the belt off, unbolt the pump. Unlike a gas motor, there aren't brackets for all the accessories bolted to the water pump, it's really pretty easy.

 

The lower radiator hose attaches to the water pump just above the AC compressor, so it could be a leaky water pump, or, even better, a leaky radiator hose.

On a different note, you might want to check your transmission fluid for antifreeze. Somehow seeing your two problems together makes me jump to conclusions . . .

 

Just a FYI....when my waterpump was bad. The only signs that it showed was a small hot water trickle down by the A/C compressor bracket.

 

The trans fluid is not discolored at all. I only noticed the drip the first time when I was parked, I saw the stones were wet. I guess I have to check into these problems a little farther to see what I can come up with.

 

A leaking water pump isn't always so easy to spot. They like to leak around the shaft seal. There is a small hole on the underside of the housing to allow leaking water to drain away. Run your hand along the underside of the pump and feel for the hole to see if it's leaking from there. Also check all your hoses in that location......lower radiator hose, heater hoses, trans heat exchanger hoses, etc. As said before, water pump R&R is quite easy, just drain coolant, remove belt and then there are only two bolts that hold the pump to the block. ;D

I jsut had the exact same thing happen to me today. I have not had any leak prior to today. I went to the bank over lunch and when I came out, I had a large puddle under the middle of the truck. Went home (less than 1 mile) watching the temp gauge very closely.

Got home and determined the leak was around the thermostat area. I decided to check the hose clamp and sure enough, it was real loose. For some reason it chose today to start leaking.

I hope you get yours resolved just as easily and quickly.
