Volvo 1996 850 T5 Estate, 90,000 miles, not had Volvo dealer maintenance since 50,000 mile service, but had regular oil changes/basic servicing at non-volvo garages ..
About four days ago, on a short journey (about 3 miles) I noticed that the temp gauge had gone just into the red. I stopped and also noticed small amounts of steam from the engine bay, and on further inspection is was coming from the coolant tank where hot water/steam was escaping. It had emptied quite alot too. Since then, I've only taken it out on one or two very short journeys (under 2 miles) as I'm afraid of doing some damage to it. The fan's working fine and there's no loss of power noticeable, though it did struggle to start this morning for the first time in two years (maybe water getting into cylinders?). There's no obvious leaks in the hoses or radiator, and the coolant looks slightly discoloured, as if very small amounts of oil might be getting in, or at least some dark deposits. The car does not overheat when standing still idling - it maintains normal, level temperature and sounds just fine. After reading the posts in this group (thanks guys)it looks fairly conclusively like the beginnings of a head gasket problem and I'm thankful that I haven't made any longer journeys since the problem began.
Since I'm not exactly clear on what has been done to the car in the last 40,000 miles, I have a couple of questions to ask to try and rectify the problem and prolong it's life a little...
- Assuming the head gasket diagnosis is correct, and I will get this verified by having a pressure test and checks for exhaust gases in the coolant expansion tank, what else should be replaced (as a preventative measure) whilst this work is being done?
- Would you recommend that I replace the timing chain whilst doing the head gasket to save on labour costs - whilst they are in there? I don't have any documentary evidence of the timing belt ever been changed, though it may (and should) have been done at 60,000 mile service before I owned the car (this service was not done by a Volvo garage though, and there's no note in the service record that it was done).
- Could this head gasket problem have been caused by a generic oil filter having been fitted during the last service or the omission of some essential work due to it being serviced at non-Volvo garages? There appears to be a number of Volvo-specific checks that might not be obvious to technicians who were not well versed in Volvo maintenance.
Any advice is welcomed. I realise that this is likely to be an expensive bit of work to get done, but I'd prefer to get everything done at once and save future costs if possible.
Thanks Tim
PS. Anyone know of a reputable Volvo specialist in the UK, Midlands area??
