It's a fairly invlved process and you usually do the serpentine belt and timing belt along with it. It's about 2 hours worth of work all together. Here's a good tutorial on it: http://volvospeed.com/Repair/timingbelt.php

you will have to check the crank sensor see if fuel pump is on when cranking engine if it is check the ignighter by checking if coils are getting signal if there is no signal check fuses and cam crank sensors

It is a security feature. There is a trip wire in the side panel on the wagon (interior), and in the trunk on the sedan. That will get it open. You can also disconnect the battery for a few minutes, then reconnect, and lock and unlock the car with the key and it should re-set. The release wire information is in the manual, keep looking.

Hi, if the car suddenly sounds different when cranking, suspect the timing belt has slipped or broken. Possibly your crankshaft sensor was loose or packing up which led to a backfire, which reversed the crank direction and caused the belt to jump. I have pasted directions below from autozone.com on how to remove your timing belt cover if you want to check the belt yourself. The last picture below shows the timing marks on the gears. If the belt is still intact, use a socket on your crankshaft pulley bolt to rotate the engine until the camshaft gears align with their marks. Then check the crankshaft gear at the bottom to see if it is aligned to it's mark. If not, your timing has slipped and you need a new belt. If the belt is bad, I can also supply directions for replacing it. Please let me know if you have questions and thanks for using FixYa.

pudh the 2 tabs in on eather side of the radio pull ,Call the dealer give them the radio part number .you got the code .

I am not sure what you mean. Please explain. Thanks!

Are rates are anywhere from $6 to $20 dollars

Good Luck

not possitive it is a cold issue, sounds like the fuel pump relay may be getting week.

Fuel filter has nothing to do with the car turning over. It may prevent the car from starting. Do the engine turn over or try to crank or start. If the car is turning over but will not start it could be fuel related. Is the battery fully charged? if not charge it. Spray some starting fluid in the breather for 3 seconds to see if its fuel related. If the car starts and goes dead it is fuel related. Do this a couple of time and you should get the same results. If it does not start it will be electrical. Good Luck!!!

Is the check engine light on? Check your fuel pump, your fuel pressure regulator, your injectors, your fuel relay, fuel filter. If you are getting gas then you need to make sure you are getting spark so check your distributor module inside your distributor, or depending on which motor you have check your coil pak for spark, test your mass airflow sensor and the connection plug to it for tight fit, your cam sensor could cause misfireing if bad. There are alot of things that can cause this so first and foremost get an ECU diagnostic on it.

Replace the entire window regulator, sounds like your track is bent or broken, most of them are made of plastic.

Depends on the particular problem, if your heater core has a leak you will be spending more than the value of the car to fix it. If you have a leaking hose a twenty buck part and thirty bucks labor. Now at a dealer that hose will be 200 dollars to fix. What is wrong and who is going to fix it? There is no average repair cost.

Sounds like a cooling system problem .

If you are getting fuel air and spark to the combustion Chambers then the crank sensor is doing it's job.possible fuel washed cylinders not allowing enough internal compression to ignite the fuel.Remove about 4 plugs and squirt a little oil down in each cylinder and let sit for a moment.Turn the engine over several times with the plugs out,clean the spark plugs,re-install and see what happens.
Hope this helps your concern,

possibly broken timing belt.

Please see my tip at http://www.fixya.com/cars/r5821173-doesnt_car_start_gasoline_engines and let me know if you have questions.

Hi!!
The Crankshaft Position (CKP) sensor, sometimes called an RPM and/or impulse sensor, is used to determine engine speed and Top Dead Center (TDC). This ensures precise ignition timing. The sensor is located at the rear of the engine block, above the flywheel. Engine speed is transmitted to the fuel control unit. The engine will not start without this signal.
To replace it, just disconnect the electrical plug remove the one fastening bolt and pull sensor out.

it means put it in overdrive or there is a transmission fault

Hi, The fuel pump relay for your Volvo is located in the engine compartment. The fuse and relay box on the drivers side by the windshield. The fuel pump relay is in the back ron of relays and the 3rd one in from the left. If you look inside the cover for the fuse box there is most likely a listing of the fuses and relays. Good Luck
