ECT vs EOT question/problem

[ksobiech282]

My truck is an 06 and I bought it back in September and finally got to drive it for the first time yesterday. Long story short my truck was in an accident with 129xxx miles when I bought it. In my driveway I had to but everything onto an new frame and did my head gaskets (oem) and arps. I also did my blue sprung and stc fitting. Now its all back together and I drove roughly 100 miles. I did about half cruzing at 70 on the freeway and my eot was ~200 and my ect was ~183. While my truck was down I also replaced the engine oil cooler. With the current temps am I in trouble already? I did not flush coolant system before engine tear down.

Temps checked by scan gauge ii and I also have egr delete from previous owner. Valve is still in and connected though. And just before I pulled in it threw a p0401 code.

Check your ECT and EOT after a cold soak over night and see how close the temps are. They should be a few degrees of each other close to the outside temp. The ECT is a little low, but its cold outside too. If the ECT never gets above 183, I would look at a new thermostat. If I remember correctly, the Delta is measured when the ECT is a minimum of 185.

Also, backflush the system, get some VC-9 from Ford and follow the coolant flush procedures. If you havent yet, get the Ford Gold replaced with a good ELC Silicate free coolant. Some folks have reported oil cooler clogging after coolant flushes, but at this point if you still have old coolant in there you may have already partially clogged the cooler. Get a coolant filter after the flush and coolant replacement.

I do also have a coolant filter and I put in a total of 4gallons of elc coolant and a gallon and a half of new distilled water should most old be coolant be out? My ect does get over 185 when I'm going slow

Ok, lets check the ECT and EOT temps a cold after a cold soak and see the results. If those temps are normal, then we may be looking at a partially clogged oil cooler.
