my coolant disappears when i drive my car for like 4 minutes and the reservoir is empty..i fill it up start my car let it idle for about 10 minutes ..look under the car i see no leaks... and then when i take it for a ride....check reservoir again its empty.....pm if u noe the problem thanks

 

You say the reservoir empties... Do you check the coolant level in the actual radiator? What does it do?

When my waterpump started leaking ('95 GSR) it would only leak for about 10 minutes after shutting off. It didn't leak while running, didn't leak while it was sitting overnight cold.

Still, whatever it's doing, you have to find where it's leaking from. Waterpump leaks out a small weep hole facing downwards toward the firewall & steering column. It drips down & collects under the crankshaft pulley, so you have to catch it leaking to see the actual source.

 

top it up, start the car, let it idle for 20mins till the fan comes on, and thermostat opens. look for leaks everywhere.
otherwise check to see if your burning coolant

how do i noe if im burning coolant?

 

well if your burning coolant its, your headgasket. so do a compression test

 

Could be a water pump leaking but you'd probably see that leaking on the outside of the block. Once the car warms up or on initial start up do you have white smoke from the exhaust?? Also..if you still have a heat shield on your car, look closely underneath it by the ports where the header bolts to the block because if you have the head gasket leaking towards the outside of the block it could be going out there and you'd never see it because it comes out and burns up on the header.

Burnt antifreeze or your header will be white spots/marks
