u need to look under truck and follow where the fluid has come from you may just need a new radiator cap. or u may just have overfilled fluid check reservoir hot level
You need to pressure check the coolant system to determine just what is leaking first and the address that problem..........
yes, leaking coolant is what happens before the pump totally dies, then you have overheating and possible engine damage soon after the leaking.
you might have a blown head gasket and the coolant is leaking into the cylender and the engine is burning it.
The overflow tank is either cracked or its overheating and leaking from the cap
If by water you mean engine coolant, yes. Loss of coolant, antifreeze, is a major cause of overheating.
there might be a leak some where in a coolant line. or maybe you have a leak in your radiator.
Look for leaking antifreeze/coolant. Usually you can see it leaking around the top of the engine. Also check your oil, if it looks milky it has been mixed with coolant and you intake manifold gasket is leaking. That being said, it is possible to have a leaking intake gasket with no sign of leaking antifreeze. Most intake manifold issues/leaks are coupled with poor engine performance and even sputtering and lack of power.
its probably leaking from somewhere else and dripping off at the tranny area. pressurize the coolant system so that you can detect the leak and go from there.
watch your coolant level because antifreeze is probably leaking in your heater core, another indication of leaking heater core is greasy film on inside of your windshield and it makes it hard to defrost.
Antifreeze is typically green, but the newer stuff is "gold". If you're getting red liquid leaking from the radiator it's probably the transmission coolant line.
Find the leak and replace the hose/part that's leaking. It's a good time to flush your coolant system, too.
What other symptoms besides leaking antifreeze? Where do you see the anti-freeze leaking?
