ok so i replaced my thermostat last night. wating for the gasket to seal. just was wondering, incase it wasnt the problem. Old thermostat seemed fine. How can I tell if the water pump isnt working properly? is there anything else that could make the car over heat? The coolant doesnt leak, except when it overheats (over flow tank) and i dont think i have a blown coolant seal, it doesnt smoke when i start it. thanks you again.

 

Smoking isn't always the first sign of a blown seal. The seal has to deteriorate enough to let quite a bit of coolant into the chamber to make smoke. Usually in the beginning stages, there isn't much if any smoke.

Now to the waterpump question, there is a "weep hole" on the pump. When it's failing, you'll see coolant/water dripping from it.

 

k thanks. is there any other reason the car would be over heating other than the thermostat and the water pump>?

 

There's not much to the FD cooling system.

Have you checked all the coolant hoses to make sure none of them are kinked?

Does it help your temps driving with your parking lights on?

Can you tell what temps your fans are turning on at?

Have you tried running your heater on full to see if that helps?

Have you done a pressure test of the system?

yes

car over heats within 5 min of driving, so i dont get alot of time to check different things
Can you tell what temps your fans are turning on at?
I believe they are coming on around 105C
Have you tried running your heater on full to see if that helps?
no

Have you done a pressure test of the system?
no

 

its will run around 85-95c then skyrocket up to 121 faster than you can blink.

 

Do this one first.

 

how do i go about doing that? can i do it myself or have to take it to a shop?

 

You can do it if you have the equipment. However, if you are asking then you probably don't. Just take it to a shop. It doesn't have to be a rotary shop as pressure testing cooling systems is a common thing on just about all cars.

 

ok. cool. thanks for your help. I work at a car dealership so i can probably do it here. If the car makes it here. I am fairley car savy, its just im extremely new to the rotories. i can tear my subaru apart and can understand and comprehend just about every part on it. My 7 is like reading arabic ( i have no idea). Just have not seen anyone work on them infront of me before. I learn by experiance. Guess im in for a big lesson.

 

Are the fans comming on ? ? ?

 

I'm having the same problem. My coolant leven doesn't go down, no kinked hoses, new thermostat, fans are coming on and my car always over heats even in light driving.

I have no idea how people are keeping their cars operating around 84C

 

me neither, even when i first got it and before it broke, it still ran in the 90's at all time.

 

i have a lil cooling issue too.. i mean i donno if the fans come on when i drive but when i stop the car n turn it off n turn the key to on for the electic componets to turn on the fan turns on....

 

o forgot to mention my car only over heats when im WOT in 5th going about 90+ but if im in a steady mph like 80 to 90 n keep it there its fine but if i have the gas down trying to acually push it.. then it over heats

 

my car overheats sitting idleing in the driveway after 3 minutes of turing on. least you get to drive yours
