Cooling problem

[microgalant]

My car begin to overheat, but i don't know where to start,i've bought new radiator cap, flush the system , but it still overheat.
I don't know if the waterpump is bad, or the car has a leak.
I've put a vid so you guys can see, it seems that the waterpump is bad.

First things to check in this order:

Thermostat
Water pump
Coolant Temp sensor
Radiator fans

A leak you would see; if your head gasket is leaking your exhaust will smell sweet and possibly have coolant in your oil.

If the thermostat is stuck in the closed position you can overheat your car, stuck in the open and it will take forever to warm up.

Don't have termostat, temp is ok, fans works, no oil in my coolant...
When I start the car, and leave it idle, it works fine, fans start and stops, open the radiator cap, you see the water flow, but when i ride the car, all the coolant goes into the reservior tank...btw I have new radiator cap....

Don't have termostat,


doesnt every car have a thermostat?? im sure they do maybe thats your problem then have you change your timing belt recently! i remember when my friend first did he never changed the pump at the same time and went bad 5 months after! thats all i can think off check that your rad isnt rusted as they can get that way.

also watching that video makes me think if its going in the over flow pipe then its not going in the coolant pipe (guess) so maybe there is something blocking it in the pipe in the exit/entrance of the rad? i know you said you flushed it but worth a shot just incase its something small (dont know how it would of got there though)

when the car idle it works fine, no problem, it happen when i ride the car, and boost it, all the water goes in the reservior tank.
I took the termostaat out my car, about 4 years ago

If you are pushing coolant under boost, it means you have a head gasket issue.

Seems to bubble a lot in the water.... looks like the time to check for the headgasket

Hmmm I have a new cometic headgasket on it, I did just dyno the car last week....or maybe I need to retorque the head?
I'll do a compression test

+1 on the thermostat. I was going to suggest testing yours in boiling water to see if it opens up correctly. You could always opt for a lower temp. one. Have you considered using an additive, such as Redline Water Wetter?

Ok took the head off today..

HEADGASKET GONE?????

Replace the head gasket.

Also, factory head bolts need to be replaced every time you remove the head; they're torque yield. Since the head is off you should replace the pos head bolts with some ARP's.

I'm using arp head studs, and the headgasket is about one year old

They're supposed to be checked for stretch and replaced as needed.

 

[microgalant]

also the arp you have to check for stretch?

It's always a good Idea get the caliper out and check them whether there Stock or ARP's

 

[MaNGiNa24]

Is that an OEM head gasket or aftermarket?

Was the head torqued to spec in the correct order when it was last replaced?

If you've been overheating there's always the possibility that you warped the head & the head gasket was just the result of the head being warped. I've seen this happen in the past.
