2000 Ranger 3.0 loosing water about 3/4 gal every 3 days, no leaks in driveway, t-stat works, over flow bottle full, runes smooth some water at tail pipe, not coolant but its cold here may be condensation.bad cap ? faulty water pump leaking while driving ? lost here

 

Possibly head gasket, i went through 3 on my 3.0. smell the exhaust and see if it smells sweet and if it blows smoke.

 

no smoke or sweet smell, I think the water is getting past the cap, over flow box is full and water warm

 

hope its a bad cap, it is the original one ! no sweet smell or any smoke

 

At least the cap is an easy and inexpensive part to try... let us know how it goes!

 

I sure will, the water has to go some place, its not on the ground, no obvious leaks no smoke or anti freeze at the tail pipe but lots of water in the overflow container and its warm

new T-stat seems to do the trick, will wait and see

 

I changed the cap, still had a prob replaced the t-stat which was rusted and falling apart, water level stays full and no more filling of the over flow bottle ya ya ya

 

not sure were to leave the reply
