Answer
When you replaced the headgasket, did you have the head checked? It could be warped, causing the gasket to fail, or worse it could be cracked. I've also seen the water jackets within the block crack if it overheated to many times.
first , the thermostat could be stuck. try replacing it. if your radiator OS losing coolant, there may be a leak in the radiator causing it to overheat, or the water pump could be bad. thermostat is the likely cause if it is not losing water.
i would have replaced water pump long before replacing radiator. also check engine oil to see if it has engine coolant mixed in.if it has then the problem is more likely to be a bad head gasket
You could have a stuck thermostat or your cooling fans aren't working.
For radiator leaks look for the following signs: The car will overheat Coolant level will frequently drop Pool of coolant or water under the car radiator Obvious leak noted from radiator on starting the car Faulty radiator cap causing the leak
start by replacing rad. cap. if that doesnt help you have a blown headgasket.
I was having the same problem with my 99 explorer. What I discovered was that the overflow tank for the radiator was empty and was causing a false reading by the temp gauge.
Look at the rear of the radiator approx. 1/3 from the top
A bad radiator cap needs to be replaced as soon as possible. Fluid can leak out causing the car to overheat. Constant overheating can lead to expensive repairs. The average radiator cap costs less than $10.00, so it's worth the investment.
not good since most transmission coolers are inside the radiator. if you drive a car with a cracked radiator you can overheat the trans fluid causing the fluid to break down and also you run the risk of damaging the head/head gasket(s).
radiator bluesWhen the water runs out of the radiator, it either means that the radiator is cracked, which means that its building steam inside your radiator. building the steam inside your radiator raises the temperature of your engine causing it to overheat and steam up on you.Depending upon where the water is coming from, the solution could be as simple as tightening or replacing the radiator cap, or tightening or replacing the drain plug,or tightening hose clamps. Check those things before proceeding.
