Top 20 1995 Volvo 850 Questions & Answers

Have you diagnosed the problem to be the head gasket, or are you guessing.

What are the symptoms.

I would be carrying out a compression check, and cylinder leakage test on all cylinders.

If it is a blown head gasket, it will need replacement, don't bother with any dodgy chemical sealer, it will not work.

Could be rear brake locking up,cars arent used to going backwards or hand brake sticking on . Would look there first.

Hello Jack Smith '95 was right about when the obd (on board diagnostic) ports were being "STANDARDIZED"... If you check on Amazon (I will put opportunity URLs at the bottom for you... You will find a large selection of devices available... Also from auto-parts stores, eBay... (etc.). Even Harborfreight.com has them (quite cheap)... but the key is the code books... These are available by car model & make. Interesting... You can get a wealth of information (with some MIS- information)... merely by doing code searches on the internet. Code readers are quickly getting better and THE BLUETOOTH versions seem to be getting more attention lately... I waiting for a decent I-phone app to work with it. As for myself... I have the basic autel version from AMAZON... simply because of AMAZON'S amazing return policy. Hope this helps!

Does the car turn over? If it doesn't it could be an immobiliser issue if you have a fully charged battery.
Is the battery the correct type, amps and cranking amps?
Check all wiring connections you you removed to carry out the work.
It could be the wire on the starter motor soliniod came off. It does happen. The same goes for a bad battery terminal connections, a seized starter or a siezed power steering pump pully bearing. Did you rotate the pump pully before fitting?

Hope this helps you.

check fuses, spray carb cleaner in air cleaner/ throttle body, if starts....fuel pump bad

You need more oil. Add until it says it is full or in the full range. Also make sure you oil plug is tight on the oil pan.

Get a scanner from IPD for $80 and it will tell you what you need to do.

If you are using port A2. error 212 is a bad O2 Sensor. if you are using port A1 error code 212 would be a bad transmission and it would behave quite badly.

Try this: pull off the battery cable and let the charge drain for 30 min or so. Unlock your doors with the key, then reconnect the cable and let everything reset.You could also pull relay #14 (see photo) which is for the anti theft system. Or the fuse.

take the car for a drive for a few kilometres before checking the trans fluid and keep the car running in park while you check the fluid level and coolent you can check the resevior to see if it needs to be topped up

Check the wires that go to the fuel pump, one is pink the other black, when the key goes to position II you should have 12 volts for about 2 seconds, if you are getting that voltage to run/prime the pump then you have a bad pump. If the car hasn't been rolled, that switch prob. isn't your problem. The sensor is located attached to the body shell, under the center console between seats I think on a 95 ....

#1. Check the secondary cable which runs to your starter. #2. Check Starter Relay (unplug, and shake it - sometimes to can hear broken stuff inside of them) #3. Make sure your cables are tight, and your battery has a good charge. (was it trickle charged ? jumping and then turning the car off will not be enough charge for the battery ; you must charge to 100%) #4. Check all grounds.

You need a new belt unit. I have replaced 2 in my car.

In the center console glove box under a cover marked OBD

EGR malfunction. Check the vacuum hose to the EGR valve first.

P1310 is a misfire code which means misfire on more that one cylinder. Cat was probably damages as a result of the misfire. Start with replacement of the ignition cap, rotor, wires and plugs. could be another issue but most likely it is ignition 80-90% of the time

You will need to replace the glove box door assembly. Common Volvo issue
