I've used this stuff in a Citroen I used to own (I know, not exactly a Subaru!), but it worked very well, sealing a pretty large hole.

Occasionally, I get what seems to be a stale smell of radiator water in the cabin of my car (2005 Blob), more often if the heater is blowing out air.

My question is (although I know the response is *likely* to be: How could you be stupid enough to even ask...) would putting a bit of Radweld into the radiator of the car be of any benefit, or is it just likely to bugger up a load of stuff in these types of cars? If there is just a small hole, would it fix it, or would it clog up everything and maybe cause things to leak?

Cheers!

 

I would not use it just find the leak and get it sorted

 

My son put some in his vw golf and it played up the coolant sensor causing running problems

 

Sounds like it might not be worth the risk then...

How would I go about finding a leak in a radiator/heater matrix?

Thanks a lot!
