You could have a blown head gasket, have a compression check done to see if there is any low cylinders,

a head gasket failure does not always allow water to get into the oil, the failure point can also be between the water jacket and the cylinder bore

    I know this might sound crazy. But if you have a automatic transmission it could be transmision fluid it well look the same. the fluid is cooled through bottom of the radiator.& well migrart to your water if theres & enternal leak

Diesel. Will Chevron DELO XLC be an OK coolant?

Look on the bottle and see if it mixes with other coolants. If so.. Use it. If not, look to see what's in yours and see if it mix with it. If not. Drain you coolant. Add water, run it to temp, drain it again. Then add your good deal.

I have a 2003 Ford F350 7.3 diesel engine,Engine run fine,but only the problem diesel mix with coolant,what could be the problem.

you may have two hoses that hooked into your radiator that help cool you oil. If the radiator breaks down inside than you need to replace the radiator. The radiator probably has four tubes or hoses bolted to the tanks. Two four transmission two for cooling oil. If so you need to replace the radiator and flush out the cooling system and clean out the water jug. Do not wait long cause you could clogg your heater core with oil. and also cause the vehicle to over heat and that is not good for diesels.leave comment

What type antifreeze to use in 2003 ford f250 diesel powerstroke

ford lists to use the ford gold premium, they advise not to use the orange extended life coolant for that year and motor, if you dont want to go to dealer then parts store should sell you the GO -5 FORD / DCX coolant. good luck.
