I notice that my freeze plugs on the turbo side is leaking a bit around 6 months ago and I have to add anti-freeze about once a month.
Has anyone ever replaced these?....or do I need my Volvo guy to do this?
Car is a 93 940 wagon with a 230FT...156,000 miles.

Andrew in AL, we can agree to disagree on this. Get the freeze plug replaced. It is probably steel vs. brass or SS and it's just going to get worse.

I am sure you are right. I was going for the quick fix - and the Bar's really worked on my head gasket problem.

Now that I think on it more - a freeze plug replaced should be pretty cheap.

Get some Bar's Leak in the grey bottle. Pull the top rad hose while cold (catch as much coolant as you can below - won't be much) - and pour it in the top hose. Re-attach and start - filling the resevoir with 50/50 mix as you go - you won't need much - if any. Let it run for about 15-20 minutes, watching the temp and resevoir. You may have to add a bit of coolant later.

I had a leak in my head gasket, and so far - so good. The Bar's in the grey bottle (not the clear one) is recommended by Jag and some other mfg. It will probably turn your coolant murky brown (did mine).

Be careful when you pull the top hose with the plastic neck on the radiator. It will probably be fine - but I know that my 91 940 neck crumbled and broke a spell back -and I had to get a metal radiator. Come to think of it - if it breaks on you - you will have saved yourself money in the long run.
