Engine Oil & Coolant Temp After Flush
I just flushed my coolant system as per Gooch's post here.I used 4 gallons Peak Final Charge. Now my coolant reading on my refractometer is -60F. I also installed a 203 thermostat and billet housing. Running down the road unloaded at 65mph, 1870 to 1890 rpm, oat 66F my oil temp was reading 218 and coolant 207. This is from my scangage II. Couple of questions here please. Is the oil temp sort of high for 66F OAT unloaded? Is -60F more than 60% ELC? The truck is a 6 speed so coolant temp should be good.
Thanks,
Bill

As long as your thermostat is working properly, then ambient temp has very little effect on engine oil and coolant temp....as least in moderate climates.
One of my trucks had a t-stat that was stuck open and I drove it like that for 2 or 3 years before I figured it out. During the cooler seasons....I would have to drive for 10 or 15 miles before I'd get ANY heat in the cabin. My oil temp would max out around 160 at 65 mph and drop down to 100-120 range as soon as I came to a stop. I just figured that was normal for a pickup truck and lived with it. Then we bought another truck for my wife and it warmed up in a mile or two and the oil temp was around 200 (during the winter). At that point I realized I had a problem with my regular truck and fixed the issue.
