#5145 of 19336 Strange Problem - AWD?
May 08, 2005 (2:23 pm)
I just bought a 1995 Subaru Impreza Wagon with a Manual Transmission. It's got 68,300 Miles and is a great little car....except.
Whenever I am going slow and turn into a parking spot, or any other slow tight turn, the car will come to a stop as if the brakes were applied and remain applied. If I straighten the wheels and move forward, after a few feet, the wheels free up and it drives with no friction.
If I am on loose gravel or pavement with loose gravel on it, it almost acts as if it's a straight axel and one tire breaks loose in the tight turn.
Is this a problem with the AWD? The Differential?
Thanks in advance.

You may try changing the transmission and differential fluids - if that doesn't help, then it's something mechanical.

Mechanical how exactly? Thanks.

Your transmission contains a conventional gear box, along with both a center differential, and a front differential. And out back, between the rear wheels, is another differential. The front and rear are 'open' type, the center is probably a fixed split 50%/50% front-to-rear.
When the wheels are pointed forward, all 4 tires rotate in unison. But when you turn the wheel, each tire travels thru a different arc, and thus rotate at different rates. The differential(s) job is to apply drive torque to all 4 corners, yet allow each to rotate at these different speeds. When it binds up, you get the condition that you describe. On drive pavement, one or more wheel will skid or hop, on gravel, they slide without turning fast enough. With careful observation, you might be able to tell which diff has the problem. If you are lucky, fresh fluids will wash out the crud that is causing this. If the components are fried, you could be in for expensive mechanical repairs to free stuck parts, or a total replacement.

Thanks Steve, I appreciate the explanation.
#5150 of 19336 I'm checking on my engine light.....
May 09, 2005 (11:40 am)
Does anyone out there know how to reset a check engine light? I've got a 2001 OBW with the H-4 engine. The CEL light came on when I was cruising on the highway (150 miles into a 300 mile trip). When I bought some gas at the end of the trip, I noticed that I hadn't tightened the gas cap from the previous fillup. Defintely my bad for that!

The light will probably go out by itself after a few drive cycles as long as the cap remains on tight, but the code will remain in the log for 40 cycles. No big deal unless you are going for an inspection soon. If it really bothers you, disconnect the battery ground lead, and step on the brake. This discharges the engine computer long term retention, and wipes it out. But you will also loose the 'learned' fuel trim, tranny shift preferences, etc., but they will be back in a few hundred miles of routine driving.

Thank you Steve. I'll just keep driving and I'll look for the light to reset itself....normally I'd go ahead take the advice offered and disconnect the battery but considering how things have been going, I'd probably forget to reconnect it and I'll be posting another query on this board asking what to do because my car won't start! Thanks again.
#5153 of 19336 Random overheating
May 09, 2005 (2:38 pm)
My 1998 Subaru Outback 5 speed has decided to randomly overheat. The 1st time was in Arizona mountains at 9100 feet on a narrow 2 lane blacktop road. After letting things cool off topped off radiator with water and put some in the overflow bottle. It didn't overheat until almost 2 months later in southern Louisiana. Same thing - no warning - suddenly the needle in the gage "hit" the Hot mark. Coasted into the Wal-Mart parking lot (good timing there). Let it cool off and put pre-mix anti-freeze (good for any color anti-freeze) in the radiator. Made an appointment with the Sabaru dealer in Baton Rogue, LA. Drove the 60+ miles on I-10 to Baton Rogue the next day - no overheating. The mechanic did a pressure test - passed the test. After some conversation decided to replace the thermostat.
Fast forward to this past Friday (geeze, May already). Almost same problem except we had just driven to our new home site at a moderate speed (40mph) about 5 miles distance. The engine was idling. Suddenly the temp gage moved up to the second mark below the "H" mark. The gage hovered around the same mark for a few minutes. Finally let it cool off and put more pre-mix in the radiator.
So today decided to try a new radiator cap as the overflow coolant was not being drawn back into the radiator.
Any ideas as to this overheating problem.

I've told others this also, and I hope I am wrong, but.....
This is EXACTLY how my 98 behaved when I had a blown head gasket. It would act up intermittently, particularly when slowing down to a stop after an extended freeway drive, such as on the way to work. Get off on the freeway ramp, come to a stop, and voila, overheating. I had to take mine to the dealer twice before they detected hydrocarbons in the coolant. The mechanic mentioned after the repair that the leak was barely detectable on the gasket.
