Is this a bad sign?
I went camping (not towing) yesterday and when i was on the open freeway the differences between the ECT and EOT was about 25-30, yes i know that is not normal and probably isnt good at all but my question is my ECT flucuates and it is obserd, thats not normal right?
ECT was about 180 average occasionally it would go up to 190 but then it would go all the way down to like 174 and at the same time my EOT was normal 206-208. When in town sometimes my ECT will go up to 200 (like once) and i would think just by going down a hill my coolant temp shouldn't go down
Im hoping its not the coolers because i cannot really afford it but i am going to do the flush and change the coolant to CAT ELC and also change out the thermostat either this week or next.
It doesnt really seem like the oil cooler is going bad or clogged because i would think the EOT would shoot up past "not normal", anyone else have an experiences like this?
