Just bought an '04 with over 200,000 miles. I am having to add about 1/2 gal. of coolant a week. I can see steam coming out of a rubber hose underneath truck. Cant tell where the hose is coming from but it sticks out in the front of the engine. The radiator hose doesn't seem to hard. It just had the injectors replaced, not sure about the cups. Any ideas? Thanks for any help.

steam? you sure thats not your crank case hose you are seeing? also does the truck smoke white at all?

No, no smoke, no puddles on the ground. Could be the crank case hose, not sure.

your coolant loss could be a few things. it could be bad injector cup o-rings and they are leaking by down into the cylinder, could be bad head gaskets.
