Turbo oil seal is probably bad. This lets oil leak into the air intake from the turbo bearing. If smoke goes away during hard acceration, then this is probably your problem. Turbo replacement or rebuild is the fix for this.

Both radiator hoses are hard why 98 s70 volvo turbo


It has been my experience that both radiator hoses get hard with age, check the hoses for age and cracking because they usually are hard right before they give out. They get hard when they get old due to excessive oil covering because of an oil leak and heat from the engine and the coolant within the hose.

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.

1999 volvo s70 rich black smoke runs bad


Black smoke indicates a rich or too much fuel condition. First thing to check is the fuel pressure regulator on the injector fuel rail. Pluu the vacuum hose off and look for signs of fuel in the vacuum hose. They will rupture the diaphragm and suck fuel in to the intake. Can also be caused by a faulty 02 sensor, bad MAF sensor or bad coolant temp sensor. If the check engine light is on check codes and post the codes.

Battery light, white smoke


You need to look under the hood, located the Broken/Missing Serpentine Belt. Repair the damage the belt did when it broke and put a new one in. The Alternator is not turning and that is causing No Power to get to the systems and more than likely, when it broke, it knocked some wires around.

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.
