Still losing water after new water pump and thermostat was installed

SOURCE: 2.3l ranger keeps overheating, been through two radiators already.

Hello Ranger Joe, eight months and two radiators is very uncommon. Question, Have you visually confirmed the leak in the radiators or is the leak near the hose connections? Replacing the radiator, cap, water pump, & the thermostat leaves only two others, the hoses and the engine block/heads. Far fitched will be something or somebody poking holes in the radiator.

dude this happened to me this weekend and i spent a lot of time under the hood. turned out i just had low coolant.

here's some things to consider:

drive the car up on a 2x6 board or some bricks or something so you can look underneath it. there should be a fatty hose on top coming from the engine to the radiator and then another fatty down low going back into the engine. There may be various other smaller lines. Now any one of these could be loose or have a hole and will need to be replaced.

Another possibility is that you have a hole in your radiator. you can put a new or refurbished one in yourself, significant task for a first timer. they can also be patched or replaced by a mechanic.

yet another possibility is that you have a crack in the engine somehwere most likely a head gasket (this possibility is the least likely dont worry)

yea its bad to run your car on H but hell I did too ooops. good luck figuring it out, if you fill it up again and look underneath is you will see where its coming from. try whiping everything down before it leaks so you can tell right away what is fresh. and dont spill it when you fill it up, i spilled like one oz and was convinced my radiator was cracked.

try to run the water pump without hoses, and add water in the 'in' side, if is powers out the other side, then it's fine. how is your water/coolant mix?

I have the same vehicle...check to see that the heater control valve is opening...usually mounted on the fire wall and has about a 5/8" inch hose that come from the T-stat....it esentially bypasses the heater core when the heat is not selected. The hoses going through the fire wall on the left (passenger) side of the vehicle are strictly for the heater - it "heat" is selected and those hoses are cold - based on what you've already done, the next conclusion would be the heater control valve...could be something as simple as a disconnected vacuum line.

Good Luck,

Mike...

Did you burp the system? these engines have a problem getting all the air out of the system. Look for a bleed valve near the thermostat and crack it openwhen the engine is cold. I believe they also had a problem with the head gasket on that year if it over heated. good luck be sue to get the air out of the heater and the radiator they can be a problem.
