My wife drives a 960 and we had squeal that turned out to be a frozen timing belt idler pulley. Now, I don't know much about Volvos other than 960's, but I can tell you what I saw on my wife's. If you remove the timing belt cover and look at the pulleys guiding it along they should look clean-ish, ...

Wow thanks for the advice there. I had taken the car to a Volvo specialist yesterday and of course the noise did not happen for him. There was still this hollow, airy noise coming from the same right-hand side of the car, but no whining. I'm doubting this is the engine or trans myself, as the car se...

The squeak from the belts can be eliminated by pouring a small amount of water on them as they rotate - it is not a permanent cure but it helps to eliminate noises when doing a diagnosis. A slight squeak at idle can become worse when the engine accelerates. How long is it since the belts were repla...

Nope, the sound is only when accelerating/deaccelerating. The only sound you can hear when the car is idling is a slight squeakiness in the belts, as they probably need replacing. (Though I did have them changed last year...)

Sorry, forgot to pinpoint that. To the best of my knowledge, it sounds like it is coming from the front around the passenger side. It's very noticeable in the cabin when driving. The AC is not on when this happens, just to add that. (Besides it was far too cold out, lol, and my AC doesn't even work ...

Well now I have another problem, which I just noticed today. The weather HAS gotten quite cold (it was 70 on Friday and dropped to the 40s this weekend, I'm in NJ) but I'm not sure if that's related or not, or just coincidence. Anyway, I own a 1990 740 GL and the mileage is about 195k rounded out. W...

Just to update you Bill in case you were interested....it was discovered some of the connectors in the bulb holders were corroded due to water....probably old seals weren't doing the job anymore and water was getting into the tail light. I get the whole thing at a junkyard and had a friend install i...

As you seem to have no problem with other lights in that light assembly it would be fairly safe to assume that the ground connection is OK. The first thing I would do, and you may have done this already, is to try the new bulb in a light you know to be working - I have had new bulbs that were dud! ...

Hello all, I have a 740 GL '90, recently the rear window and passenger side tail light went out and I had both bulbs changed. The rear window light worked again but the passenger side tail light does not work even with bulb replacement. I need to get my car inspected this month and am trying to save...
