After I drive the car i jack it up and get under it, but can never find the leak..cant you spray something on there and you will be able to see air or coolant escaping? Thanks.

 

Get some dye that shines in black light and add it to the coolant. Then get a black light and find the leak.

 

I assume that you see a puddle on the ground after driving? Where is that puddle located in relation to the motor?

 

Well I park in the street, and my last car had a major oil leak. I need to throw some cardboard under there and check to see, but so far i have seen nothing on the ground. Some ppl said it can leak into your frame, and then spill out when you drive...im not sure, but i gotta find a big piece of cardboard and check that out i guess.

 

If you dont see any coolant on the ground, why do you think you have a leak? Are you loosing coolant ?

 

Loosing coolant very fast...when im driving it everyday, I have to refil it like every 3 or 4 days. Even after I drive it one day and it sits for a few, it will still be low when i open it up.

 

Do you see white smoke out the exhaust?

 

I had the same problem with my 95. It wouldn't leak when the engine was cold but it seemed like when the thermostat would open, it would leak out of the bottom of the w/p. Had to replace the w/p to fix the problem

 

Theres a kit you can buy that has different types of dyes, it comes with small black light and glasses that help see the dye. I seen it on one of the car programs on TV not sure price or stores.

 

Pep Boys sells the coolant leak detection kit. Cost is about $50.
