    I just had this experience with the following 1987 740 GLE
    1. The heater fan was making noise so I replaced it
    2. The panal heater switch malfunctioned
    3. The smell - it was the fuse box - corrodeed
    4. The fuse for the fuel pump melted ????
    5. The fuel pump is fine and the FUEL relay was the problem that caused all of this chain of events! the relay sits behind the fuses and the conact shorted to the metal case! My advice do not wait
    the car will die without the relay working properly it is a quick 5 minute job unplug ang plug relay

Was the car primarily in a Southern state--no winters? If yes, it could be the wiring harness that leads to the rear wiper/stop light inside the rear tail gate. They usually break at the flex point, and short to the frame.

Strong fuel smell


Stop driving until you get this figured out, as you are a fire hazard with possible fuel leaking or being pumped somewhere it shouldn't be....Look for wet areas...Be careful about not smoking and electric lights, as fuel fumes are VERY flamable.

Gas smell


This is a nasty problem with this car. It is the smell of mostly Sulphur. It comes when the Catalytic Convertor gets faulty. Replace it and get Smell-free. Thank you Sir, Have a nice day.

1996 Volvo 850 wagon sputtered @ intersection smell of antifreeze


I would check that the auxilliary drive belt that runs the alternator and probably the water pump hasn't just broken, causing the engine to overheat and the battery to run flat. Just a suggestion, hope it helps.

Hi,
May I suggest a locking gas cap. You could put a large piece of cardboard under your car and if there are any drops the next morning that smell like gasoline you might find the leak if there is one.
Cheers,
Ken

The engine shutting down is probably a bad VSS(vehical speed sensor). The electrical problems are most likely due to loose wires and bad grounds. Clean and tighten all conections starting with the battery cables and the ground wires under the hood and under the dash. You have to find a mechanic who specializes in Volvos or you'll lose your shirt in trouble shooting and repairs.

Car Heater smells strange


from he Popular Mechanics site if the smell in your car is like maple syrup:


(1) SMELLS LIKE: MAPLE SYRUP
WHEN: After the engine has warmed or possibly even after it's shut off for a few minutes.
THE CULPRIT: Coolant containing sweet-smelling (but toxic) ethylene glycol is leaking from somewhere. It could be coming from a radiator or heater hose, a failed intake manifold gasket or cylinder head. It might be coming from a leaky radiator cap or the radiator itself, especially if you smell it outside the car. A strong odor inside the passenger compartment probably means a bad heater core.
