#6648 of 19336 Engine gets hot, cooling fan runs while driving
May 30, 2006 (4:57 pm)
I have a 1998 Subaru Forester, with 101,800 miles, automatic, AWD . It runs great until recently I notice it gets really warm inside the cabin when I'm driving. It gets worse especially when I have to make multiple stops while out running errands in town. It also happens when I've been driving for about 30-40 minutes on highway. The temperature gauge looks normal at mid range, never gets high or into the red zone. No steam ever comes out from radiator or under the hood. I do notice that the cooling fan is running when I pull into parking lot. I can hear it and think it might be on while I'm driving (as the engine gets hotter). I also notice my car seems to drink more gas than usual!!! Any ideas what's wrong with my car? Thanks in advance for all the suggestions.

You might check for a clogged catalytic converter first off...if it is clogged it overheats and throws off tremendous heat. A muffler shop or regular Subaru shop can install a bypass pipe. Have you noticed a loss of power at all?
If no power loss, then I'm probably wrong unless your exhaust system has shifted and is now too close to the floorboards (or perhaps a heat shield has fallen off?) and I guess next thing I'd check for is a sticking heater valve. If you feel no heat coming out of the vents with the heater off, then I'd check for engine overheating with a numerical heat gauge or radiator thermometer. Your gauge could be wrong.

Something is up with the cooling system. I'd have the radiator pressure tested, and maybe have the temp sensor looked at, too.
Are you losing coolant? Look there first, that would be a "have it towed to your mechanic" type of problem - the dreaded head gasket leak.

When the engine is hot (after coming home from work), I notice the coolant level inside the coolant reservoir is very full, almost up to the top, but no sign of leaking coolant anywhere. When the engine is cold (early next morning), I open the radiator cap to check, coolant level looks normal. And the coolant level inside the reservoir goes down a little, but still way above the FULL mark.
I had a complete radiator heating/cooling service done last October, with radiator pressure tested, flushed, hose, belt tensioner replaced, etc. Just had timing belt and water pump replaced a couple weeks ago.

Sigh of relief.
OK, that sounds normal. As it gets hot, the coolant expands in the radiator, and some of it travels to the overflow tank. Then it comes back when it cools. Perfectly normal.

at least for me ..
I have a 2001 Outback base wagon with about79,000 miles on it .. recently the ABS light came on and then would go off at times ...
I began to notice that the ABS light would come on when the lights were on, but when I turned the lights off, the ABS light would eventually go out. IF I turn the lights on, the ABS light comes on shortly afterward ..
since this started, we have replaced the battery ... it still does this ..
I also have since noticed, that when I drive with just DRL's, and put the brakes on, that the dash lights all 'dim' when I apply the brakes, and brighten again when I release the brakes. I never noticed this before, but then I usually just left the headlights on at all times.
OK, it's been awhile since I've read this thread so if any of this is explained earlier I'm sorry ..

I presume the battery cables are free of corrosion since the battery has been replaced.......or are they?
Also check both ends of the cables to be sure they are not loose.
The symptoms suggest high resistance in either + or- common connections to the battery/ground.

Over the last week or so I've been hearing what sounds to be knocking coming from my rear passenger wheel well, but there is nothing wedged or obstructing the wheel. Then it started coming from the front drivers side wheel. A loud knocking sound, and as I shifted and accelerated it got louder and I could feel almost banging from under my feet.
I hear the noises when the clutch is engaged or not engaged. On turns I hear it more prominent?
Does this sound like a CV Boot issue?
So, the knocking and banging is getting worse and I'm taking it in to be diagnosed- what would you guess this is.

Also have the alternator checked (accessory belt tension, too). Sounds like there's not enough electrical juice for all the accessories.

Tell us more - is it speed dependent? Does the pitch change as you speed up and slow down? Is it all the time or only over bumps?
I suspect the wheel bearings, actually. Have them inspected soon.
