Coolant leak

[FordGuy8790]

Ok, so my '90 ranger is leaking coolant from the reservoir. More specifically, the coolant is overflowing. I replaced the radiator, radiator hoses, and the heater core, but it didn't help. I replaced the water pump, and thought it was fixed for about a week, but then today there was once again a puddle under my front driver's headlight. I replaced the head gasket about 3 years ago. I'm just not sure what else could be causing this. The truck hasn't overheated yet, but I have been adding coolant into the radiator every time I drive it. Any help would be appreciated.

there are test strips/kit that you can dip into the coolant....and test for exhaust gases in the coolant. it would seem that you are down to bad gasket and or head

how about the radiator cap...was that replaced too?
double check hose clamps

I haven't checked the radiator cap, so I'll try that. There's no coolant in the oil and the engine is running fine. The exhaust doesn't smell like the last time it blew ahead gasket, which is what is confusing me. But, like you said, that's pretty much all that's left...

by all means, rule out the simple things 1st...check the cap.
if the cap doesn't cure it or a rechecking of hoses and respective clamps.

Pretty sure you know what you're down to.

it is good that there is not a sign of coolant in the oil.
