If the coolant temperature sensor (ECT) is aged, the cold start fuel injection wont be correct. There is no 'extra injector' like on First generation fuel injected cars.

If you know how to use an Ohmeter, you can check the performance of the ECT to spec.

My Volvo spotting patience was rewarded with a nice black 850 with R spoilers which I did grab a pic, to be loaded

They made about 100k P80s a year with about 40k coming to our shores

That battery may well be damaged beyond repair by bouncing around. The 1999- cars need a solid good battery or they wont run well. Test the fuel delivery system by measuring fuel pressure at the rail - you can 'rent and return' a fuel pressure gauge at Autozone or the like. A pencil type tire pressu...

With a new-to-you car, its good to start at Stage 0 and run all the old coolant out with water, and replace with fresh Volvo stuff. With a car with a bad radiator, someone has probably been topping it off with all kinds of stuff available at inopportune times. A jug of Volvo from FCP will cost you $...

Those bleeders are really high quality and I have never broken one, but I dont go under to flush coolant. Drop the air guide, remove the lower radiator hose and dump the old coolant. Now put a garden hose into the reservoir and idle the engine for 15 minutes with the hose slightly overflowing the co...

Sorry, left that out. I have found with both the P80 and P2 platforms if you flush, then dump the water, it will leave about 5 liters of space for a jug of coolant concentrate. That will take you pretty close to the 50-50 mix, which is fine for any of the 48 States. Canada and Alaska might run a bit...
