Sounds like a intercooler coupling or hose blew off. The shop or mechanic might not have tightened a clamp all the way. Check that out first before going into further troubleshooting.

My 1994 Volvo 850 turbo has been loosing power mainly going down hills. It will turn over and start right after, then I put it in drive and it dies again. Last night I waited an hour before trying it


It may be your fuel regulator, mine did the same thing, and the turbo should go almost down to no power while going down hill, thats normal

Just had my 120000 service done on a XC90 which I just purchased. It was running just fine and then started to consume oil like crazy. Took it back to mechanic and he said the turbo is going out. No...


There is the possibility,the turbo was going out and the previous owner had thicker oil with oil treatment additive in the engine,hiding the turbo seal problem.Did your service include an oil and filter change? Your new regular (proper viscosity) oil may now be showing the leaky turbo seal.Did you have a oil change done at your service?Once you have the seal/turbo rebuilt,may sure to always idle the engine a minute before shut off after fast driving.This will increase the life of the turbo seals.

1990 burton my overdrive not working and i change relay and overdrive switch 123 is fine help.


It sounds like the OD solenoid to me you can either replace it or use this bypass kit offered by IPD. Like the desciption for it says "How many times have you used the OD button on the shift lever to shift down for hills or while towing?"

The "Bertone" is a great car. Keep it running and happy! Not many around.

Do the air purge test below.

The fins/turbine on water pump can be totally worn out.

====

When the car is completely cool,check the electric fan(s) for smooth rotation.

Clean/check/change the thermo sensor,contact and wire.

===

Excavate air pocket in coolant system / check for head gasket leak

This test will kill two birds with one stone.

===

MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!

RAN THIS TEST IN A WELL VENTILATED AREA ONLY!

You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!

===

Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .

Top of the coolant reserve tank

Let it ran for 10-15 minutes.

Monitor for air pockets escaping from coolant reserve tank.

Small amount of bubbles is OK at 1-5 minute mark

After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.

If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.

Give the thermostat host few gentle taps.

If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.

Let engine cold down and top off coolant reserve tank.

Start monitor for coolant lost

===

A coolant flush is require every 2 years or 24,000 miles.

I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.

Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.

Have you replaced the timing belt? if not i would highly recommend doing so. these cars need to have the timing belt replaced before it breaks otherwise it can and will cause major engine damage.

Loosing power/transmission


Could be an issue with losing boost from your turbo. Can you hear your turbo spinning correctly? I know some TDIs have turbos that are a little easier to hear than other for no apparent reason. Are all your vaccuum lines in good shape? Are the hoses from the turbo to and from the intercooler in good shape? Maybe when something (vacuum hose, intercooler hose) gets warm enough it flexes and leaks. Right when this happens you should pull over (if possible) open the hood and have someone give it a little fuel. You might be able to hear a vacuum leak or an air leak in the intercooler piping. It could also be a bum sensor that sticks at a certain value and when you stopped and restarted you unstuck it.
You need to start eliminating items or find any other symptoms you can to help narrow this down. It is a loss of power right, and that's what is keeping it in the lower gear? Or does it seem more like it is just stuck in lower gear?

Volvo slows down going up steep hills when air temp >95 Fahrenheit


THOSE VEHICLES HAVE A SECONDARY FUEL PUMP THAT FEEDS FUEL TO MAIN PUMP UNDER VEHICLE. THE SECONDARY PUMP IS INSIDE THE FUEL TANK. IT IS POSSIBLE THAT THE 2NDARY PUMP IS STARTING TO SEIZE ON YOU. CAUSING POOR FUEL PRESURE AND MAKING VEHICLE TO LOOSE POWER
