Dear Brickboard,
Having read archives regarding catastrophic loss of coolant into tranny; I'm considering taking the indie Volvo mechanic's advice and having an external AT cooler fitted. I don't do any towing (yet) but the Indobrick (251000kms) does do some nasty short-trip, stop-start, heavy traffic city driving and occasional full-load family camping trips. Can anyone give me an idea of a fair price range for having this work done? Is it a worthwhile preventative? Bearing in mind the 700/900 FAQ on the topic I should just replace the existing stock plastic radiator (age unknown). Or do both? Any experiences with this matter?
Thanks,
Mike

If you do not do towing, the internal cooler is plenty.

You can spend less and use an external cooler, but when will the rest of the radiator fail?

You're right - I just needed to hear it again. Called PO to discuss: he had no idea of age of radiator but did mention the last time it was pressure tested he was told it had a tiny leak so it's high time for a new radiator. I'll stretch to the external cooler as well for the extra peace of mind. Got a nice towbar which attracts requests for towing help from friends moving house etc! Thanks for the reply.
