Head Gasket on 04 Super Duty 6.0L

Nebr. MM · Feb 26, 2011

The anti-freeze in my 04 Ford has a scorched oder. Does the anti-freeze need to be changed or does it get this oder from a head gasket leaking? 135000 miles.

If I recall correctly, the AF should be changed every 36000 miles on that engine. If it came with yellow coolant, I think it did, it barely meets Fords, or Internationals spec for that engine.

Check the front of your engine for leaks even if there is nothing on the ground. Had a 03 6.0 that smelled of AF with no signs of leakage, but did have to add everytime I changed the oil. Took the truck into Ford for a recall (several recalls on that engine) and told the service tech about the smell. Ended up replacing the water pump. Seeped enough through the weep hole not to drip on the ground and burned off. Be aware, if that's the problem, everything from the bumper to engine comes off to get to (lots of hours). My 6.4 is worst.
