The best way to find a rad leak is a pressure tester. Can you borrow one or rent one? If not its off to the mechanic.A small leak will blow back onto the engine while you are driving and evaporate,leaving no trace. a pressure test is the only way to track a small leak down.IF and only if there is no obvious leakage you might be looking at a head gasket.The coolant in this case is going up the tailpipe.good luck

The water is not hot at all but the radiator is shooting the water out of the cap, and sending the water to the resivore and makes the resivore over flow.


Sounds like you may have a bad radiator. It may be clogged and the coolant is not able to go through it causing it to come out the cap and reserve tank.

Water reserve bottle is emptying and engine is getting how


flushing a radiator is a waste of time and money as blocked cores do not flush. Have a pressure test done on the coolant system and check for external leaks. have a compression test done to check for head gasket and cracked head. Have a flow test done on the radiator and if shows signs of blockage replace the radiator .. Always fill the radiator at the radiator cap and not the reserve bottle. The reserve bottle water will not go down until the engine coolant starts to cool so if it is going down when the engine is hot then you have a bad leak in the reservoir bottle.

Engine overheating, 2000 deville


The problem is that more heat is entering the water than is being extracted by the radiator.

But there can be a lot of causes for that. If you have a head gasket leak, it can introduce hot gasses into the water, increasing the heat load while raising the pressure in the cooling system. That in turn can push water out of the cooling system, and into the recovery reservoir, where it can't help with the cooling of the engine.

If the fins of the radiator are blocked or folded over, that part of the radiator will not contribute much to the cooling.

If the internal water passages of the radiator are blocked, the area of the radiator is effectively reduced.

A worn out bottom radiator hose can collapse from the suction of the water pump, blocking the water flow.

If the fuel mixture is too lean (not enough fuel in the given volume of air) the engine will generate quite a bit more heat, possibly overwhelming the system.

When the engine is cold, the thermostat (a valve in the hose where water exits the engine to go to the radiator) is closed. This prevents water from going to the radiator, and that in turn prevents water coming from the radiator to the engine.

Water instead leaves the engine through the heater hose near the upper radiator hose, and circulates right back to the inlet of the water pump. So the water circulated through the engine, but it has no way to shed any heat it picks up. This speeds up the warm-up process.

The water circulating this way passes by the back of the thermostat, causing the thermostat to warm up along with the water.

When the thermostat reaches its opening temperature, it starts to open, allowing some water to go out of the upper hose to the radiator, and therefore some water from the radiator to enter the engine.

Right away, the water in the engine falls below the opening temperature of the thermostat and it closes.

The newly cooled water gets warmed by the engine, raising it to the opening temperature of the thermostat, and the whole process begins again. But this time, the water coming from the radiator is just a little warmer.

Eventually, the thermostat will stay at a partially opened position where the cooling by the radiator just matches the necessary heat loss through the radiator.

If there is not enough water, the surface area of the radiator is effectively less.
If the radiator is blocked, or the fan is not working properly, the surface area of the radiator is effectively less.

If the thermostat doesn't open properly, the radiator is not sufficiently utilized.

If too much heat is generated by the engine, it can over heat (heavy load at low speed will make a lot of heat without spinning the water pump fast enough, for instance).

These are a few preliminary tests to see what's going on. With a stone cold engine, start it and let it idle. The heater hose leaving the thermostat area should begin to heat up but not the upper radiator hose.

Once the heater hose starts to become uncomfortably hot, the upper radiator hose should start to warm up, slowly at first.

If the heater hose does not heat up, there might be insufficient flow throw that part of the system.

There is a quick check a shop can perform to see if you have exhaust in the water. There is a syringe they can use to draw the vapor in the radiator through a sensing liquid. If it changes color, you have a head gasket leak.

The radiator cap only need to be replaced if it is letting the coolant move into the reservoir improperly. If you coolant level remains fine, that is probably not a problem.

HOW DO YOU FLUSH THE RADIATOR IN FORD MONDEO ST 24


Well you take out the down hose,all the coolant in the radiator will go, remove the radiator cap put a water hose in the radiator,then open the tap .Let the water flows until you see clear water going out from the down hose.When finish put back the down hose like it was,then put your coolant in the radiator,then it is finished the flushing.

How to flush the radiator


on the radiator there is a bolt on the the bottom of the radiator,u must unscrew it ,this is point to service the radiator,well you have already unscrew that bolt the water in the radiator will go out,then take out the radiator cap then put a water hose in the radiator now see the dirt going out from the service point,let the dirty water goes until you see clear water goes out ,now you can close the water tap ,screw the bolt,the service point,by then u can put an antirust solution in the radiator,and fill the rest with water, put the radiator cap,and your radiator is up to date

Water not staying in Radiator


yes, not having an overflow reservoir for your radiator will cause you to lose water. As your engine warms up the water expands and creates pressure in the cooling system. When the pressure reaches a certain point(usually about 15 psi.) the radiator releives the pressure by releasing water into the overflow tank. When the engine cools back down the water shrinks pulling water back into the radiator from the overflow. If there is no overflow, the everytime the engine warms up on a drive water will be lost and not recovered on cooldown.
