Coolant question

[snakyjake]

The safest answer is to use exactly what Ford recommends you use.

If you wish to explore newer and perhaps better coolants, here's this info:

Be careful about colors. Be careful about "ELC". Be careful about OAT, HOAT, SCA. Don't mix.

Check with a Ford dealership about using their HOAT coolant. They have the Ford Motorcraft Gold Premium. I believe it requires a full flush.

For OAT coolant, what you want is a heavy duty diesel ELC that is OAT and meets Caterpillar EC-1 specifications. Not SCA, not HOAT, not hybrid.

For the T444E engine, build date 2/99 and after, you can use OAT coolant.

For the DT466E/530E engine, build date 8/29/98, you can use OAT coolant.

I also don't remember which engines have problems with cavitation. I thought some cylinder liners were exempt from having to use cavitation protection.

I'm not sure if one is better than the other. No one is going to drive this engine up to 600,000 miles, and doubt even 300,000 miles. Does anyone really want to keep fluid in their engine that long? Are there really any advantages? I doubt there's serious advantages. I have not heard of anyone losing their engine because of using the correct coolant with their engine. Fleets are still using SCA. SCA is still the most popular.
