Oil cooler line replacement / faint smell of anti-freeze S70 1998

Autoclimate control equipped. Cooler temps here in the Texas hill country have dictated a warmer setting on the thermostat. I noticed just a faint smell of antifreeze coming through my vents. I haven't noticed any leaks under the car or in the cabin. By the way, where is the heater core??? How do I know if it needs to be replaced?

I've also developed a leak from the oil cooler lines. Where can I get a set for my car without getting gouged by the parts department at the dealership?


Thanks!
Vinnie

    The heater core is to the right of the gas pedal. You need to pull the panel off to determine if there is a leak. Antifreeze flows through the core at all temps, it is the ducting that determines if you get heat or fresh air.

    Most often, it is the O rings that go bad in the oil lines. New lines can be ordered online at FCPGroton or http://www.autohausaz.com/ or other places. Some dealers offer online discounts as well.

      Hi Klaus,
      Thanks for the info. I take it it's easy to access /replace the heater core?
      Do you replace the o-rings or do you just order the entire oil cooler line?

      Thanks!
      Vinnie

        The heater core is about a 2 hour job. Go here and take a look:

        I have no idea why the glove box is removed???
        Just remove the side panels to find the leak. You can still use the car with the panels removed. Then order the parts you need.

        If the oil cooler lines are leaking at the radiator, I suggest first trying to replace the O rings and use hose clamps to gently tighten the line couplings. Be careful, the radiator couplings are plastic and can crack. Do NOT use hardware store hose clamps, they will shred the lines.

          The leak seems to be near the oil filter....it's moist around this area on the cooler lines. Leak is about the diameter of a penny after the vehicle is shut down.

          I've been driving the car a lot today and haven't noticed the smell at all........hmmmmm.

            If the air guide/splash guard is still on your car, take it off. Clean it and leave it in your garage for a day or 2.

            The oil cooler lines do not go near the oil filter, they go from the front of the engine to the right side of the radiator.

            There is a weep hole at the bottom of the intercooler which will let collected oil drain out when the turbo is boosting. This is normal. It usually runs to the driver's side of the air guard and then drops out by the bottom intercooler hose.
