Sorry for your situation, but this is one of those times when it's best to put the car out to grass. The car is 15 years old. I kept a Subaru running until 300,000, but there was always 'just one more ...

I drove with my Parking Brake on for 30 mins: should I be worried?

If it has been driving fine since then, all you have probably done is worn the brake pads down. Not fatal - but check when you pull the handbrake on that it is solidly holding the car stationary. If ...

Car overheats idling in traffic

My top suspect would be a radiator fan that isn't running when it should. The fans assist in transferring heat from the radiator to the surrounding air, and are most needed when the car is stationary....

I drove with my Parking Brake on for 30 mins: should I be worried?

1) Parking brakes only engage the rear brakes, so your front brakes (which provide the majority of stopping power) are 100% fine. 2) On a car with rear drum brakes, which I believe your car has: The ...

2006 wrx overheats going slow but not at speed

I don't think there's any reason to suspect a head gasket right off the bat like that. The first thing that comes to mind is the electric cooling fans. They are on the car specifically to keep it ...

Why does my overheating car cool off on declines?

You may have developed an air bubble in the system, probably from the reservoir falling off, or from the mechanics not bleeding the cooling system after emptying it. There'll be a pocket of air in the ...

Cascading Repair Costs following Blown Head Gasket on a 2004 Subaru Outback

Can a blown head gasket cause overheating, without losing coolant?

Yes, it's possible. Also, the bit you lost that you think may be a leaking pipe is actually being turned to steam and blown out your exhaust. The car runs fine until the engine gets hot enough for the ...

1995 Honda Civic lx overheating

At a guess? From your description I'd bet it has a blown head gasket. The only way to tell if this is so is to do a sniffer test (search for "block tester") at the radiator. There are testers which, ...

Idling motor and running AC for 4-8 hours in 100 degree heat?

It shouldn't cause the vehicle any issues. Realistically, all you'll be doing is burning fuel. The wear will absolutely be minimal, mainly because at an idle, there is very little stress put onto the ...
