Alas spring is here and I dusted of the Brick for some summer driving.

It's been a couple of months and eveything runs great. Thennnnnnnn...... without a warning (that I can figure) I'm driving along about 50 mph and the engine bucked for a second then the oil light came on, then I rolled to a stop.

Can't get the engine to start,but turns over (electrically).

Timing belt? Or.......???

PS I have no leaks and no puddles. oile filter and lube in October, along with a new flame trap and fuel filter.

It is normal for the oil light to come on when the engine stops, alternator light as well. First steps to diagnose is to look into oil filler cap while cranking starter to confirm cam is turning, this eliminates timing belt as a possible fault. Next check for spark at plugs to eliminate possible ignition system fault. If these are OK then problem is fuel related and most likely possibility here is fuel pump relay. Check these items and report back for more assitance in diagnosing.

Well, it turns out that the tensioner came apart and the belt slipped off the pully(s). Volvo shop estimates about $500 for a new belt, tensioner, and perhaps a water pump.

Sound about right?

I would've guessed a couple hundred, adding the water pump pushes the price up a bit but it's a no-brainer to replace it now if it needs it. Probably a bit steep, but see what the others say. I'm accustomed to doing my own, <$30 belt, around $50-$75 tensioner, $130 water pump (all $CDN), and a couple hours of my time. I guess if $500 is their worst-case price, it may not be too far out of line. Did they say how many hours' labor they would be billing?

They said about 3 hrs total WITHOUT the pump. Add an additional 1/2 hr for the pump and $140 for the unit, etc. So depending on if it's original equipment or showing signs of leaking it will be replaced. But if it looks like it is a replacement, probably no pump.

Hope this is about ballpark for this type of stuff. I like to shadetree simpler jobs! 8->

I also have a '93 945T. I’ve bought a water pump and timing belt, but haven’t actually installed them (I bought them because of a leaking water pump, but then the leaking stopped). I know I need to actually replace them because they haven’t been replaced in a while, and besides I already have the new parts (sitting in my garage).

Anyway, the prices seem very high, here are the prices for the timing belt, tensioner, and water pump through ipd:

Timing belt: $25
Timing belt tensioner: $43.50

Water pump with seals: $56

Keep in mind that ipd isn’t the cheapest place out there either, I'm sure you could save a little more by picking it up elsewhere.

Did you get the price estimates from the dealer, or an independent shop?

These are dealer costs and OEM Volvo parts. Mine is a 940 non-turbo.

I wouldn't trust nay local garages because most of them do not know anything about Volvos and would mark up the parts costs even higher. The ones that I would kinda trust, I could give them parts that I purchased, but they would also take longer to do the work and I would end up with the same or higher expense anyway.

After reading my Bently manual, I would rather bow out of this task.

Yes, I could piece meal the parts and take some short cuts, but I would rather be guaranteed that the service was done correctly and not worry about a can of "extra parts" that I may come up with if I tried it myself. Or, do more damage not knowing what I was doing or mis-adjust something and self inflict more problems.

I think it's about $200 high, but it's like paying insurance to make sure it's done right.
