Replacing 850 thermostat 850 1994

posted by  someone claiming to be Juan P. on  Sat Sep 19 07:59 CST 2015 [RELATED]


All,


I just acquired a 1994 base 850 from its original owner - it's a 5-speed car and I'm absolutely loving it. It doesn't feel like it has 197k on it (current odometer reading).

However, I am planning to do some work on it later today. The first order of business is to replace the thermostat. I know I am going to use a Volvo OEM part. Which one should I use: 82, 87, or 90 degree? Folks I know have used these to varying results. (Note: Temp readings are in Celsius) An old Volvo tech I know says to stick with the 87.

    If you get OEM, which you should as they fail in the open position, a dealer will give you a 90 degree. Either 87 or 90 will produce the same results without harming the engine. Both will be open within 1/2 mile of driving at 0F to give you cabin heat.

    Verify that the coolant is correct for the engine, either Volvo or G6 (?). If you drain using the radiator, remember it is plastic and cannot be over torqued!!

      Klaus,


      I purchased an OEM thermostat. The parts guy at the dealer said it's a 90-degree (Celsius).

      So I can put it on my car without any harm or damage to the engine? Just want to make sure.
