Question about 1989 Volvo 740

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

1989 740 Turbo sedan, with 160,000 miles -- a volvo teenager! every summer, when the air temperature is over about 95 degrees Fahrenheit, and that is quite often in northern California, the Volvo has difficulty going up long hills and starts to lose power. Other driving conditions are fine. Has anyone experienced anything similar? None of the local mechanics can id the problem. thanks, Elena

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

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

My 2002 S40 shakes when the car goes up a steep hill and smooths out when the road levels.


Most up hill problems are Ignition related,such as
individual cylinder coils or a coil pack, depending on
what your car has.

You may or may not have a check light on the dash

A more violent & more sudden, somewhat similar lack
of up hill performance ,would be the EGR Valve.

If you never had any trans issues since the car was new,
& I don't think that is the case with the mostly under load
& up hill issues,I would change the trans fluid again,not
have it flushed,just change it & add,LUBGARD in the RED
BOTTLE,no other product or brand.

I will assume your spark plugs have been in the motor less
than 3 years or 60,000 miles

Also not really related but effects fuel trim or adjustment,is the
front O2 Sensors,the ones closest to the motor before the
converter. Change them at 100,000 miles.

Check fuel pressure with a gauge. I like to go on a road test
with the gauge taped or tied to the windshield or wiper arm.

Any kind of vacuum leak will cause a problem

Make sure the air filter cover is on correctly

Stalling problems with 1994 volvo turbo won't go pass 30 miles.


Sounds like the fuel filter is dirty... When have you replaced it last? Possible that the pump is bad but I would start with the filter.

1990 volvo 780 turbo I replaced head gasget . I know the mecanical timeing is right. whent for a test drive Ran good for 3 miles. Going up a hill and heard a pop and now it barely runs. Is it the turbo?...


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.

yes I do believe you can easily get 200k out of her. I have seen a few volvo's with over 250k on them. As long as maintenance is kept up, she'll keep purring

95 volvo 850 burning oil. no leaks. How do i check the turbo seal or the the pcv system


Hi, I have a 1996 Volvo wagon 850 turbo. I just bought it and when you hold the rpm's at 3 and a half it was blowing out smoke after about 600 miles it stoped smelling like burning oil and doesn't blow out any smoke. But I use a court of oil in about every 150 miles. What could this be?
Thank's Jodie

95 Landcruiser Turbo warning light comes on under heavy load


If you are "lugging" the engine, you will get increased exhaust temperature (EGT), this will trigger your "turbo" light(not a good thing), ideally you should have an aftermarket "pyrometer" fitted to your car, this will show you the optimum revs etc you should be using in any given circumstance.Or revise your driving technique, ie change down gears earlier.
The turbo should be idled down after long trips or heavy towing, this allows the oil temps to stabilise and turbine speeds to stabilise, thus idle for 2-5 minutes.

Acceleration


Chevron 91 octane with Techron works well.  I just did an 8000-mile cross country run with good results (responsiveness, acceleration, idle)
