Radiator water tank always emty

leak radiator possible,do a pressure test to confirm.that is the best way.gd luck

Replace small hose and clamp, that hose come's from your transmission, goes through another tank in the radiator, to keep the transmission fluid cool, hope this was very helpful.

Hi!!
On the bottom of the radiator, there is a drain valve, just open it and drain fluid into a container, if you want faster drain, remove bottom radiator hose.
NOTE: DO NOT OPEN SYSTEM WHEN HOT, COOLANT IS POISONOUS FOR PETS, KEEP IT AWAY FROM THEM.
Good Luck!! Rate this post!!

from what you describe I am sure it is the water pump that is leaking, check the pump bearing for play to confirm

could be the water pump or a hose, try to locate exactly where the coolant is coming from

- Make sure the engine is cold and not running.
- Drain the radiator fluid by opening the drain plug at the bottom of the radiator or for a better/faster drainage and cleaning, carefully remove the bottom radiator hose by first loosening the hose clamp.
- Open the radiator cap and water rinse/flush the radiator core via a garden water hose until you no longer see any dirty water coming out of the bottom hose (or drain plug).
- Flush the radiator over flow (plastic) container by overfilling it with your garden water hose.
- remove garden water hose, carefully refit the bottom radiator hose, tighten the bottom radaitior hose clamp, refit/tighten the radiator drain plug.
- refill the radiator with approved radiator fluid for your climate and also refill the radiator overfow tank to the indicated level..
- Refit radiator cap
- Start your engine until it warms up and check for any water or steam leaks. Refit and or replace any faulty hoses or radiator (regulator) cap!
It is not difficult and have fun!

CHECK EXPANSION TANK HOSES FOR WARE , ALSO CHECK RADIATOR HOSES, IF STILL CANT FIND LEAK, PUT RED FOOD COLORNING IN IN EXPANSION TANK AND LOOK FOR LEAK.

check for the hoses and their connection pionts if all is ok than the water pump has to be replaced.

When driving down highway only, it overheats? When running steady, I take it you mean, sitting idling? If it's only overheating at highway speeds, and all else has been checked out & is o.k., I'd take a close look at rad hoses for soft spots (easy to squeeze) that may be causing hoses to collapse at highway speeds & restricting flow of cooling system. Another thing to try is, turn your heater on high fan & high temperature when it starts to heat up & see if temperature gauge goes down (cooler) at all. If it does, then rad not doing it's job properly.

Run the engine and look at the header tank , is there lots of air bubbles coming back out of the water if is then the head gasket may have split and that is down to either a can of Radweld or a strip down repair

If the radiator is not uniformly hot them I would go for that as your problem

Normal operation is that the engine starts the thermostat is closed , engine block heats up and opens water starts to circulate around the block

So to check that you need to fill the radiator with cold water run it for a few minutes check the bottom hose it should be cold

The stat opens and the bottom hose should get hot as the water from the block is pumped into the radiator for cooling.

The radiator should get hot all over and the cooling fan should kick in when the sensor hits the over limit stop.

If that does not happen then get someone to remove the stat altogether (It is only there to get the engine block warm quickly in cold regions )

In which case the bottom hose should go from cold to warm to hot
