Volvo 850

there are two little black buttons on the side of the clock you must push in both of these at the same time. also changes from Fahrenheit to Celsius and vice versa.

yes it will ,its an interference engine meaning that pistons will hit valves bending them.to cure this problem is to either purchase a set of new valves or you can buy a new engine or you can avoid this by just simply have the timing belt change good luck peace.

To start, the Ignition key must be in position II, engine not running. Locate the two diagnostic sockets just inboard of the washer fill cap. The "A" connector (shown above) has a jumper that is stored in the lid of the "A" diagnostic connector. The jumper is used for both diagnostic connectors. Listed below is the information retrievable from the various connections. A1 Transmission B1 Climate Control A2 Fuel System B2 Cruise Control A3 ABS B5 SRS A5 TCU (Transmission Control) B6 Power Seat A6 Ignition System A7 Combined Instrument Normally "Check Engine Light" information will be found in A2. Put the jumper into A2 and push the black button for one second. Count the red LED light as it blinks back information, blink, blink, pause, blink, blink, blink, pause, blink, blink, is an example of the response you would receive. 2-3-2 would be the code retrieved, now push the button again for one second, again count the blinks, keep checking for codes until one of them repeats, this means you have read all the codes. Now to clear the codes, push and hold the button for 6-7 seconds, release and as soon as the LED comes on push and hold the button for another 6-7 seconds. Now push the button for one second and read the codes again, you should get 1-1-1 (no faults). You Must Read All Codes before Clearing. Turn the ignition off and then start the car, the check engine light should be out. It is always a good idea to check for codes, clear them and then drive the vehicle to see if they return before replacing parts. The transmission can ask the check engine light to be turned on, so if you try clearing A2 codes and they wont go away try reading the transmission (A1), clear them , and then go back to A2.

After contacting a Volvo dealer, they recommended the Haynes series of manuals for the 850, each section details the codes and faults detected.

1994 wagon 3270-3390 lbs.

it might be the engine idler pulley or power steering pump. if it's e.i.p.

bearings gone bad. replace it. the p.s.p. may have air in the lines. top

fluid off with lucas power steering treatment, turn wheels loc to loc

make sure front wheels are off ground repeat @ 10 times. inspect

return hoses clamps reservoir

if the noise is a squeeling sound, check the drive belt, if worn change it @£17 if the noise is a squeeling sound, check the drive belt, if worn change it @£17

If the transmission is not in a lower gear than "drive" when the arrow flashes, or your transmission is not set for "winter driving mode", you could be experiencing a PNP switch going bad. The PNP is a switch that sits on top of the transmission near the shift linkage. It's a pain to to istall and costs about $120 most places.

It says it all for a 850!

the relay needs to be replaced. you will find it behind the hazard switch (attached to the switch - a long skinny thing)

I looked forever till someone told me where it was. Even the Volvo parts guy didn't know and Lawrence Volvo of Walnut Creek, CA would not tell me...

The oxygen sensor is used to infer the rich/lean mixture of the engine. Without a signal from the sensor the computer will default to a general mixture to allow the engine to run. Overall I'd expect strong smelling exhaust, loss of power, poor fuel economy, and the service light to be on.

You can troubleshoot the oxygen sensors easily with a digital volt meter. These sensors have either 1 or 3 leads. For single lead sensors connect a digital volt meter to the single lead, leaving it in the circuit, don't unplug it, or cobble a connection so it stays in the circuit with the car. Measure between the sensor and ground on a 1 volt scale. You should see this value vary between about .2 and .8 volts on about a 1 second interval. This only is applicable if the engine is fully warm!

The 3 wire sensors have a heater built in to get them to operating temp. sooner, thus you need to find the sensor lead from the heater lead. Obviously the heater lead is either ground or 12 volts, so the remaining lead is the sensor.

Do you have your terminology right....The injector relay would be the computer right???

The fuel pump relay could cause that problem!!!!

good luck and let me know

To open the trunk of a 1996 Volvo 850 glt from the inside first you need to fold down the rear seat, remove the trunk lid panel so you can access the rods. Move each rod up and down until you find the one that releases the trunk.

search the web. there is someone in California who does nothing but fix ABS controllers. His website explains how to remove it and he sends an email explaining how to re-install it. best $125 I ever spent on my car (local mechanic quoted $500).

This is water in the oil, usually caused by head gasket failure

Could be a crack or hole in the pickup tube. I had that problem in a '84 940GLE.

10.6 for an automatic, add another 1.5 hours for a manual (clutch adjustments, etc...)

Don't forget that there are always extra part costs.

Trouble code P0611 means: Furl injector control module - performance

The Volvo 850 1997 fuel pump relay is under the fuse box compartment, you would need to take out the upper portion of it and then you would be able to easily find it undeath. elyunque000@yahoo.com

The obd2 connection is located right above the gear shifter. There is a cover that looks like a coin holder that pulls up and the connector is under it.

How do you know that it is your car?

If you are referring to the air conditioning. Unit then it has many parts in different locations. the compressor is located on the passenger side of the engine. If you stand at the passenger fender it will be just under the power steering pump. The condenser is located in front of the radiator at the grill of the car the condenser is inside the duct work inside the car and is the hardest to replace. To get to the condenser you must remove the entire dash. Lastly if you are looking for the service port to put in freon it is on the passenger fender close to the windshield washer fluid jug.

Most likely you are burning antifreeze. This could be cause by a leaking head gasket or an intake manifold gasket. This condition needs to be corrected quickly, as it could lead to catastrophic engine failure.

your rear camshaft seals are old...they are about 15 dollars at your local dealer. replacing them is a pain. like two to three hours worth of work...well I am referencing my 94 85 turbo anyway....

buy the hanes or chilton's repair book and you should be able to do it yourself.

Dealer price? 400 dollars plus mostly labor money...
