Ocassional differences in oil and coolant temps 15 to 16 degrees
Most of the time my coolant and oil Temp differences are about 8 degrees. That's typically empty on the highway or pulling a 4500 lb trailer around town and on country roads. Recently I rented a 30 foot RV trailer and every so often when pushing it just a little I would see a rise in Coolant and Oil temps with a 15 to 16 degree difference. Wouldn't last more than a minute or so. Seemed like this would occur when the thermostat would open and coolant temps would drop quickly but the oil temps would remain almost unchanged. Didn't really push the truck cause it just wasn't necessary so most of the time I would see temp differences of about 8 to 9 degrees.
Truck has 107,000 miles on it and has had 2 coolant flushes during the course of the years and milage using the Ford Gold Coolant and staying on top of the modified Ford flush intervals and procedures. Getting close to time to be thinking about flushing again.
I've heard the use of evans coolant with no water will slowly remove some of the silicates that tend to be left by the Ford Gold coolant. Don't really want to replace the oil or EGR coolers unless absolutely needed.
Question 1) Do these temps sound normal?
Question 2) Would you switch to Evans coolant with no water at this point without replacing any oil or egr coolers?
Question 3) Should I get an SCT to simply shut the EGR valve off, no power mods?
Thanks for any and all help
