I drive 20 minutes each way every day, at highway speeds- approx 15-20 miles, the truck is brought up to temperature since repair was done before leaving. I have not done 1500 miles since the complete job was done and when done the oil was changed with synthetic as usual. Up until this issue happened, I never warmed to temperature, drove like any othe north american vehicle for 75000 miles..never a problem, I change the unit which makes it somewhat new like original....and now we have to warm up drive excessively...I dont understand...what was good before that worked for so long...now all is needed to change, even though all parts are new.
All said, I have followed every recommendation (all new parts- warm up before drive-long drives-higher revs, etc) yet the problem is always there...
