I have a small crack in the plastic radiator housing, resulting in a leakage of coolant. I am concerned that using the radiator stop leak will have a negative effect on the passages in the turbocharger. Is this a concern or can it be ignored and used to help temporarily repair the leak?
Thanks Guys.

I just do not use them. Once I used the type with pellets after a few days all my rubbers hoses exlpoded. They were so soft you could insert your finger into them. ohmy.gif Just get a new radiator.

From everything I have seen and heard, it's not worth the few weeks that stop leak will buy you. I tried to patch one in a 940 I used to own and it wasn't worth the effort. There is a high probablility it will gum up something that you don't want to have gummed. Just pony up the cash and get a new radiator.

Stop leak probably will not fix the problem but if you insist on stop leak I would recommend BG products stop leak...why not just put a rad in it?

can you post a pic of the area that is leaking? I have used fiberglass before to fix a radiator crack

I figured if it didnt fix it I wasnt out a whole lot. Truck ran great till I wrecked it. Fiber patch stayed on for 18+ months

Stay away from it, especially in a turbo car. I know radiators are not cheap, I just did one for a lady in her 850 turbo today, but they are cheaper than a blown head gasket or worse. Right?

The new radiator will be on its way in a few days, i just need something to hold up and prevent me from having to buy a new jug of coolant everyday. The crack is right below the upper radiator hose, i will try fiberglass or jb weld and see what that will do, thank you for your replys.
