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 thing' to repair on it. For your car, the main issue is that the head gasket repair was bodged. They didn't get the timing correct - if your car was a DOHC ...

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 you notice vibration, then I'd worry about pads/disks being warped or damaged. You may find though that you need the handbrake cable to be tightened, as it may ...

While the other two answers were ones that were going through my head while I was waiting for the service truck to arrive, the actual problem was much simpler (although much more expensive to fix) The engineer initially looked in the radiator coolant overflow bottle and saw it was at a sensible level, but after having a quick look at the oil dipstick he ...

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. This doesn't mean that the fan is bad. It could be that the relay is malfunctioning or there is a break in the wiring somewhere, so I would try to rule those ...

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 cool at slow speeds since you don't have natural air flow. Get the car up to temperature, open the hood and wait for the fans to come on. If they come on you ...

Your car will be fine; any issues would have shown up by now. "My indication lights dont work so I didnt see any red light on my dash" For me, this is more scary/important. It's not hard to fix the bulbs - about an hour max for a mechanic - and essential for safety.

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 parking brake is simply a cable you pull which puts mechanical pressure on your rear brakes that your brake pedal hydraulic system normally would. However, the ...

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 system that's making the car overheat. Does the car lose power when it's overheating?

A non functioning radiator fan could have those symptoms. In your car the fan is most likely shared by both the radiator and AC. When driving there is sufficient air flowing across the condenser and radiator. When you slow down the fan should take over to keep the air flowing. If it's non functioning it could cause the AC to blow warm and may overheat. ...

I concur with user9181; I would add a suggestion of having a non-dealership mechanic render a second opinion. As noted, redecking the heads requires removal of the timing belt, and on reassembly it is easy for an inexperienced parts-changer (oops, I meant “mechanic”) to install it incorrectly. a new timing belt should always be used. if the alignment of ...

Looking at a blow apart diagram on your bike, it appears you have two radiators, one on each side of the faring, for your bike. One or both of your radiators may be blocked or partially blocked. Take the faring off and check to see if there is any ash/trash stuck in the fins. Also, sitting in slow traffic will not allow a good amount of air to come over ...

They make a head gasket leak detector kit to determine if it's leaking. I would be surprised if you mechanic didn't have one. If he or she doesn't they are not that expensive. Here is an example below See my answer here for more info.


7

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 thermostat to open up, at which point exhaust gases are let into the radiator. The details of how/why is a bit long, but this is what happens. How do I know ...


7

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, when in contact with hydrocarbons, change color from blue to green to yellow. Here is an example: The only way the fluid will change color is in the presence of ...

I am leaning toward the water pump. The cool radiator and heater core are a sign that the hot coolant is not being moved around. Coolant should always flow through the heater core while the temperature is turned to hot, regardless of the thermostat. It could also be the heater core is clogged ( or heater core valve not working) and the thermostat is stuck....

A few things spring to mind: confirm radiator fan operation (per user3188168's suggestion) The fans are vital in ensuring air flow across the both radiator and A/C condenser when the car is stationary or moving slowly. A few things could cause them to not run: blown fuse(s) bad relays wiring open lack of command for the fans to turn on from the ECU (...

It would be good to ask the mechanic to explain to you how they are sure that it is the head gasket – head gasket problems often share symptoms with other problems. One way that a head gasket failure could cause overheating would be if the gasket failed between a combustion chamber and the cooling system. Combustion gasses could leak into the water jacket ...

Yes, it will. However, your biggest concern is going to be getting enough air flowing over it. Do yourself a favour and go look at the engine bay of a 200x model Subary Impreza WRX. The intercooler is mounted flat on the top of the engine and the characteristic scoop forces air onto it to cool the intake air. The same type of thing might work for your ...

You have a leak. If the white smoke is coming from the engine compartment, then you are leaking coolant from radiator, hose or gasket. If the smoke is coming from your tailpipe, then you're leaking coolant into the engine itself (bummer). If it's coming from the tailpipe, take it to the mechanic and bend over. It's going to hurt. If it's in the engine ...

I think this points at the thermostat being bad. The reason I go in this direction is due to there being no heat coming from the heater vents. I'm not sure if Subaru has it this way, but many heating systems in cars only divert coolant from exterior of the motor to the heater core. If the thermostat is not allowing (much or) any coolant through, you'll only ...

I think the overheating episode did a permanent damage to your car. A gasket could have cracked or the head could have warped or even cracked, thus allowing water into the engine itself. Too much heat in an engine can cause serious problems because heat causes metal to expand. The hotter the engine gets, the tighter clearances become until there are ...

Once your system expels as much fluid as it can via the pump there is still an additional amount of fluid that is left in the block and other areas that the pump can't push out because there isn't enough fluid and pump is just attempting to push air through the system. Some engines have block drain plugs. You would need to remove those, allow to drain and ...

A catalytic converter incorporates a structure that is coated in precious metals. When catalytic converters first came out that structure was ceramic balls coated in the metals. This didn't work so well and the structure was changed to either a honey comb or a monolith, both ceramic. The tubes of the honey comb run the length of the converter. A monolith is ...

All of this comes from: http://auto.howstuffworks.com/catalytic-converter2.htm Ok, attacking each of these in order: What exactly is a catalytic converter? It is a device in the exhaust path of your car that scrubs unwanted gases from the exhaust stream. How does it work? In chemistry, a catalyst speeds up a chemical reaction without actually taking ...

On Symptoms... The boiling and smoke are a result of the high temperature due to a cooling system malfunction. The fact that your temperature dropped again is indicative that the system works sometimes. The question is, why didn't it work here? Root Cause... What you really want to understand is why the cooling system overheated in the first place. Was ...

I don't think so I've had many experiences with strictly oil cooled engines. In particular the 1986 Suzuki GSXR 750/1100 platform. They went strictly oil cooled with a giant oil cooler and 8 quarts of oil. As you can see, this motor is filled with oil galleys and has no coolant or radiator. Another note, I live in the desert of the US Southwest where ...

I finally got a chance to investigate more and figured it out. After letting it cool during the initial trip, I was able to check the coolant, and it was bone dry. I added about 3.2 liters to the 3.3 liter capacity radiator. I noticed the seal of the reserve tank was damaged, and the radiator cap seal was falling apart as well. I refilled the radiator and ...

I would seriously look at improving your oil cooler. I doubt going "larger" is the immediate solution, I'm betting it's the airflow across the heat exchanger. Relocate the cooler, modify/improve the ducting, find cooler air to flow across it, etc. On my FPROD '72 BMW 2002tii, I was able to drop oil temperatures from a frightening 280 F peak, to a more ...


6

Some thoughts: think about interfaces where could coolant and oil mix. The head gasket is one place but there may be another place like an oil-water heat exchanger. Under normal circumstances I would expect the oil to flow into the coolant reservoir and not vice versa due to pressure differentials (oil is usually at a higher pressure than coolant). In your ...

There are so many things that could explain slow overheating A compromised head gasket is just one of them. Other (less involved) reasons include: a radiator fan that doesn't turn on when it should low coolant flow (e.g. failing water pump) debris inside or in front of the radiator Without knowing the specifics of your vehicle, you should see loss of ...
