I just got done changing my timing belt, water pump, re-sealed oil pump, etc. All went relatively smoothly. Then when I refilled my coolant, I got some air trapped, and the car they a check engine light. Got the fluid all refilled and pulled the code. PO115 coolant sensor. So now how do I get this light to go off? Or did I fry the sensor?

I am in the middle of replacing my timing belt, and the last time it was done on my car they did not put the timing belt guard back on, so it is not there. Is this really necessary? I know these are only on manual cars, and I have not had it on mine for the last 60k but wanted to know anyone’s thoughts on this. Do I have to have it since autos do not?

Thanks!

Great, is there a good site for de-coding the codes?

How do you pull codes on a 91 subaru? I have a freind with a check engine light on his car.

Sorry this is not true. First off, the AWD systems used in Subarus differ, depending on what transmission you have. Automatic-equipped Subarus use a computer-controlled hydraulic clutch pack, similar to those found in an automatic transmission, to transfer torque to the rear axle when the sensors detect a 20% difference in axle rotation speeds between the front and rear axles. Normally torque is split 90 front/10 rear. Not really all that different from most of the other AWD systems. Manual-equipped Subarus use a viscous coupling, similar to a limited slip differential (and certain full-time 4WD transfer cases) where under normal, dry circumstances the torque is split 50/50 until the physical difference of the rotational speeds of the axles causes the hydraulic fluid in the coupling to heat up to the point where it acts as a clutch, forcing the two axles to turn at the same speed. It's basically the sameas full-time 4WD without the extra low gear. It can transfer torque front and back almost 100/0 or 0/100 if necessary.

97 was the first year of the hood scoops, but this is an easy swap. Yes there are issues, the 1.8 and 2.2 have some rare HG issues. I just purchased a 1990 Legacy for my brother that blew a HG and it has 135,000 miles. It is fixed now and ready for another 200k. It is rare but still could be an issue. The 2.5 has a higher failure rate but probably around 10-20 percecent failure rate.
