Hi
My car after 10 minutes or so the coolant temp alarm start and the temperature start raising. I already change the thermostat.
What can be the problem? Can it be the water pump or is the sensor?
Please help me here.
Thanks

 

its an alarm for low coolant

 

air pocket in the system, faulty ast pressure cap or blown motor. take your pick.

 

I remove the AST and so far the engines runs good I think

 

Yea, the alarm goes on but the car dosen't look like is getting hotter. The radiator dosen't even get warm.

 

since you removed the ast, you mostlikely have airbubbles from removing it. that will cause the alarm to go off.

you might also want to check the connection, one time i had that problem, after driving home 2 hrs from pa, realized the wire was stripped.

 

So you think by burping the system should be good? Is not the water pump?
