I have a 1998 V70. I recently had the radiator replaced because the upper neck was broken off. The shop had a difficult time getting the hoses to seal properly. Every time I took the car home it started leaking again. I had to bring it back 3 times after installation because of this. They finally ended up shaving of part of the neck to make the hose tight enough.

Shortly after I noticed more coolant leakage in my driveway. It got worse and I took it in again. Now they say it's a broken turbo hose.

My question is: Could the multiple compression tests have cracked the turbo hose? Or would it have probably needed replacement anyway?

Thanks much.

 

Moon Girl. Probably not. Compression testing simply replaces a spark plug with a compression tester. Both seal the combustion chamber, so logically there is no means for a compression test to harm your cooling system's pipes.

I've never done a T5 compression test, but I have done so on engines ranging from a 3.5 hp Briggs & Stratton up to a small block Chevy V8. The process is identical for each cylinder. Doesn't involve the cooling system at all.

 

you mean a coolant pressure test. is it the clamp leaking on the turbo coolant hose ?
if so replace the hose and two clamps

 

The turbo hose was replaced. I don't think it was the multiple tests. They showed us the hose and it was worn out! Thanks much for the replies.
