My 94 EB bronco leaks anti freeze

I have 94 bronco 5.0 with a new 2 core rad. and a brand new water pump that i just replaced.My problem is it leaks after i use it,i'll shut it off and come out 5 or 10 min. later there will be a little spot of anti freeze.I can't find the problem.If it's running it wont leak,only after i shut it off it will leak.I change the hoses,rad,and water pump(not a rebuilt one).It drips under the rad.Could it be my fan clutch on the water pump.Is there anyway to test it.I loose anti freeze all the time,not much.I have 2 broncos and both of them do the samething.Both of them have new everything and still loose anti freeze.What could it be,I'm at wits end.Any help would be great.

What you need to do clean off the front of the motor with degreaser and hose off all residues, wait till the next day after driving and crawl underneath to see exactly where the source of the leak is. Could be a loose hose clamp, thermostat by-pass hose above the waterpump, thermostat housing, corroded timing cover that the waterpump bolts to and has two passages to the block on both sides, follow the trail of antifreeze its really not that difficult to find the source and not a problem specific with the bronco , sounds like you just haven`t fixed the real source of youre leak yet and BTW no coolant passes through the fan clutch......

Hope this helps...

Broncomania,I will do what you said and try to pin point the leak.If the fan clutch is not spinning fast enough would the engine be a little hotter and when i shut it off between the heat and pressure it over flows a little.I will start with cleaning the front of the engine,then follow the trail of antifreeze and go from there.Thanks broncomania,i will let you now how i made out........grasshopper

Re: My 94 EB bronco leaks anti freeze

Sure thats possible but im assuming you have an overflow tank off to the side as mine does and you seem to be unsure of where the coolant is coming from. I hate to admit it but currently my bronco AND my wives mazda are both loosing coolant *only* while parked , out of the waterpump weep hole and hers is loosing quite a bit more so on cooler nights, but i simply dont have the time to do anything about it right now, especially hers since its a DOHC V6 and will require a timing belt with a waterpump x-change. All im getting at, is pinpoint the source first cuz a simple undertightened hose clamp can make you think you have a bigger problem than you actually may have ....
