That's why is call a leak. Check all your coolant hoses, water pump, heater hoses, radiator, coolant reservoir, exec... Any freeze plugs exc. Could be your heater core is leaking. Let us know where you think the leak is coming from? Why do you think it is leaking. Do you smell antifreeze from the AC vents?
Fluids in a vehicles must be maintained to keep it running well. Coolant leaks because there is a crack somewhere, a tube is torn, or the clamp is too loose.
If you do not visibly see a coolant leak, have the cooling system pressure tested. If the leak is not obvious it could be internal.
Possibly a leak in the fuel system somewhere.
Fix the coolant leak.Chances are the water pump has a problem. They were known for having a leak and with no coolant you have no cooling.But you may have a coolant leak elsewhere also. Your cooling system will need to be checked out.
get the system pressure tested. that'll tell if you have a leak and if so it'll make the leak gush making it easier to locate. tweek
You have a leak in the cooling system. Pressure builds up after 20-30 minutes of running and a leak anywhere in the system is going to get worse.
This should happen automatically. Are you losing coolant, is the cooling system leaking somewhere? Have you just changed the coolant? Unless there is a leak, the system should purge by itself.
A coolant pressure test is used to detect a leak on the coolant system.
Have the coolant system pressure tested, the pressure test will increase the coolant leak.
A leak in a coolant system can usually be fixed by replacing a hose. If the leak is at the end of the hose, a new clamp might be necessary. If the radiator is leaking, the radiator might need to be replaced.
what is the question? why it would overheat???? if so: because -thermostat is stuck closed -or no coolant -or head gasket leak -or coolant system leak -or bad water pump -or clog in coolant system -or ......
Mine is in the timing chain cover gasket. You can find your leak by pressure testing your coolant system.
