Hello and welcome to justanswer
If you're on the road and cannot pull in the curb, you will have to turn up the heat and turn on the blower.
By turning up the heat it actually helping the engine to dissipate the heat.
The heater core inside the core is disspating the heat source from the engine.
If you're idling then shut off the engine immediately.
So next time when you're on the road and see the temp gauge goes up.
Turn up the heat and the blower.
And slowly pull off to the side and shut off the engine.
Remember do not open the radiator cap!
Is there something wrong with the temp gauge? I also took off the radiator cap(when cooled) and noticed a lot of brown sludge.
Just let the engine cool down and see what is causing the overheat.
I guess I need to know the cause so I can get this fixed
It is possible that the temperature sender has issue.
Temperature sender is usually mounted on the termostat housing and engine head.
is this expensive to fix?
Temperature sender - No.
The brown sludge is metal from the radiator.
Should i get my radiator flushed out too? It has been a couple of years
Is there any coolant in the radiator?
In the overflow tank I could see some?
No, not yet.
I would recommend you to find out why the engine is overheated.
There are several possiblities.
1. Lack of coolant - coolant leak
2. thermostat is bad
3. headgasket is bad
4. coolant fan is not working
5. The radiator is clogged.
6. The coolant itself is bad.
7. Faulty radiator cap.
I have been afraid if the head gasket all along as I know there have been problems with this subaru. Worth getting fixed?? Costly??
It depends how much you like the car.
that really doesn't help? Are we talking big $$$$
You could check the headgasket by doing the following
You talking about $1000 to start with.
The mechanic will need check for the engine head.
He needs to check if the head is cracked.
If there is a minor cracked then he has to replace it.
The head cost another $600
What year is this car?
well i do have a trusted mechanic so i will at least have some options 2000
Do you see white smoke from the exhaust?
I mean white constant smoke
Open your radiator cap - turn ON the engine. Do you see bubbles?
If yes- the head gasket is leaking.
i will do that in the am
Also check the tip of the spark plugs
If is really clean then you have headgasket problem.
ok thank you
Also check if you see coolant on the tip as well.
There are all the symptoms of headgasket issue.
Subaru are known to have headgasket issue.
Do you have any further questions?
