Joe..would you mind posting part numbers for the SS bolts to this thread please here's what I ordered from McMaster Carr 92290A188 Metric 316 Stainless Steel Socket Head Cap Screw, M4 Thread, 50mm Length, .7mm Pitch, packs of 10 92153A418 Metric Type 316 Stainless Steel Split Lock Washer, M4 Screw ...

All M4.3 and 4.4 (Mot 5.xx on P80 for that matter) use A/C high pressure sensor and pressure level to select fan speed (hi or low). Engine temp also is used but usually if fan is running for A/C pressure reason it exceeds the cooling needs for engine. The separate EFI and Ignition on earlier 850 use...

The M4.4 is pretty well mapped out, so to speak, but at the end of the day, it’s also clear that the M4.4 ECUs aren’t compatible with the M4.3 cars without pretty extensive modification. Pretty far from plug and play. Outside the known territory, there are thousands of differences that are either u...

+1, if it hasn't been done before I would HIGHLY recommend taking care of that. Many people overlook the fact that on low mileage cars, parts still fail due to time. Timing belt should be replaced every 10 years regardless of mileage on low mileage cars.

When was the timing belt done last? And by timing belt Chuck means if the timing rollers, tensioner and belt have ever been done. Leave the Volvo water pump alone, some people foolishly replace it at the ~100k timing belt job. But the water pump can easily go another timing belt change. If the roll...

Coming soon!

In 17 years of driving my 1997 850, not one day did I think "this is better in new cars" about any interior feature. I can go on and on about the remarkable and awesome design of my 850. The interior never once felt poorly designed. Good design lasts. The controls were properly placed. The...

Turbo 96 is Motronic 4.3, not 4.4. 97 850 GLT with the low pressure turbo engine was the first turbo 4.4 with the 98 high pressure turbo versions getting 4.4 in 1998. My recollection is that 4.3 in a 4.4 car gives an air conditioner issue as the pressure cycling switch on low side line is a signal ...
