    Don't guess, you will need to get the code that is stored in the computer, when the check eng lite is on a code is set in memory. Go to Kragen auto or any parts store like it and they will run the test to get the codes, record them then and post them back on this thread.

Your friend is on the right track, it does sound like it cvould be spark plugs but get the codes read as well, it is very common for coils to go out on those cars which will also give a misfire and lack of power.

I NEED A HEATER HOSE DIAGRAM FOR MY 98 VOLVO S70 T5 TURBO PRIOR OWNER BYPASSED THE HEATER THANK YOU JAMES CUMMINGS


You will likely need the heater hose junction (Volvo p/n 3522035) since it always leaks and it connects the heater core to the heater hoses on the firewall. The kit usually contains the retaining clips, but not the O-rings to connect to the heater core. You will also need the outlet and inlet hoses (9186847 and 9186849). The length, angles and configuration of these hoses will help you understand their orientation in the engine bay. They can only go on one way. Else, they won't connect to the pipes from the engine.

Why would my 1998 s70 suddenly decellarate from 75 mi p/hr on interstate to 0.what could be the cause, no engine noises or smoking


Did the engine stall or did it just lose power but stay running? Did the gauges fall to "0" or idle?

Usually when something major like that happens, the check engine light will come on and there will be codes set in the computer.

I would start by checking the codes, and if at all possible, use Volvo's VIDA and DiCE interface to make sure you get the right codes. Some generic code readers can't read all the Volvo specific stuff.

That will get you closer to the actual problem.

Rule out the simple stuff. Do you have enough gas in the tank? The gas gauge might be wrong and you're empty. The ETM could be wonky and on its way out. Google "Volvo ETM" and read up - there's a sticker on it and the color of the sticker could indicate if you have the old (likely faulty) module or not.

Ignition wires - these engines are coil on plug if I remember right (they changed around those years '98 or '99) and then you check the little wires to the coils.

Depending on if you have a high pressure Turbo or not. The engine in my S70 T5 is a high pressure turbo 2.3 litre. Look on your driver side fender(under the hood) for the VIN Tag and it will tell you what engine is in your car.

Where is the location of the turbocharger on my volvo s70 t5.


If you open the hood and stand in front of the car, you will see a pipe that runs over the top of the engine. If you follow that pipe towards the windshield it will drop between the engine and the firewall, the turbo is there at the end of the pipe.

I have a 98 volvo s70 and i dont know the engine size how do i figure out the difference between 2.3 or 2.4


All S70's have a 2.4 liter. There should be a numbers like 2.4 or 2400cc or something like that. The 7th and 8th vin digit is the engine. 55 is a B 2454 S engine. If unsure call the dealer parts dept and they can tell you, based on the VIN number.

Electronic Ignition Fault Light On


It is probably due to a faulty sensor somewhere, but without proper diagnostic equipment it is virtually impossible to tell which one.

A modern fuel injected engine will have sensors to monitor throttle position, manifold pressure, coolant temperature, air temperature, crank speed, camshaft position, exhaust gas oxygen, pre-ignition, etc, etc, etc.

Diagnostic equipment will be able to read the fault code from the vehicles computer and tell you where the fault lies.

The light cannot be reset manually. It will go out once the fault has been rectified.

Hope this helps!
