I have a small leak in the bottom of my radiator. When I opened the cap it was full with coolant and no room to pour in the product. What now?

Drain some out using the drain-cock at the bottom of the radiator OR suck some out using a turkey baster.

does this work on ac compressor leak?

Nope! You have to use a special sealer for A/C leaks that also has a dye in it to detect where the leak is in case the A/C Stop Leak does not solve the problem.

Will this work to prevent a leak from egr valve into the radiator coolant? i have a egr leak in my audi q5 diesel.

I buy this for dodge grand caravan . Didn't work

My mechanic said this stuff will affect the thermostat and the heater core? Is that true?

did not affect thermostat. IT WORKED.HOW ABOUT THAT
