right way to check this

[POWERSTROKEDSC]

What is the right way to check the oil/coolant temp. differance? Is it just idling without a being driven hard or drive it hard and see what the differance is? Reason,
I drive normal and my oil/coolant temps are within 6 degrees, when on the interstate pulling my bassboat it goes to 11 degrees the most I seen it. I realize its within tolerance, but whats the correct way to check it?

It's my understanding that EOT should not exceed ECT by more than 15 degrees under any condition.

And in my experience, my EOT exceeds my ECT by the greatest amount at full operating temp under load. The larger the load, the more the EOT exceeds the ECT.

Yeah it should not exceed 15 degrees even towing though it may get over 10. Having just rebuilt my cooler I run about 5 degrees difference just cruising and 8 or 9 when running it hard.

Same here...

So anytime the differance is greater than 15 degrees. I didnt know if there was a certain way to check it, under load vs no load. Got it though.
Thanks

How are you guys getting these readings? Do you have one gauge that you flip a switch for that reads both EOT and ECT, or 2 separate gauges?

I have a DashDaq I use to monitor my stroke. I think some on here are using the Edge Insight.
