: Coolant leak aditives

01-22-04, 07:44 PM

Does anybody know how this aditives are. Do they really work?
I've a small leak on the radiator (some drops when the engine is hot).

The instuctions say that I must spill the aditive in the radiator, but it has no "hole". Must I spill it on the coolant recipient?


PS: my aditive is Wynn's.....good?

Never heard of Wynns. I have always used Bars Stop.
Your car doesn't have a radiator cap?

No it has not.... it is a Catera.
I must spill it in the "coolant compartiment" (expansion chamber, i think)?

Normally, that wouldn't work. But since you have a leak, it will pull from the coolant resivor. You will probably still need to get that hole fixed though. But the Bars Leaks stuff will help.
