So I replaced my water pump and the thermostat in my inline 6 and it doesn't over heat now but it will drain the radiator in half a day of driving, any advice or help?

 

Not much info there Cowboy, how bad was the over-heating before you replaced the pump, you need to have the heater on so that cavity will fill up or you coolant level will drop after running the vehicle. Any white smoke/vapor coming out of the exhaust?

 

The over heating was horrible I would drive 30 mins and the check engine light would come on, it no longer overheats but still runs warmer than normal and it would have vapors before I changed the pump now it ha none
