Had a water leak. Noticed the radiator empty but reservoir full. Thought fixing the "leak" problem (replaced water pump and thermostat: now no leak, but..) would resolve this but it hasn't. When I drained radiator to replace the pump, the res. tank stayed full. Completed job, refilled, etc.. Everything runs great but still need to flush the res. tank. Any suggestions? Maybe a clogged hose or something? No crimp in the hose itself.

Thanks,

 

I have a 2000 model, and its doing the same thing. but its also overheating, before I replace things that arent broken I would love to get more info on reasons this could be happening. I can fill up my radiator drive it for a bit and its fine. when i get home i can let it sit to cool off open my hood and poor a gallon of water in my radiator.... idk whats going on. but would love to find out.

 

Sounds like a leaking intake manifold gasket. Look under your oil fill cap and look for signs or smells of coolant. Does it smell like coolant from the exhaust?
