Unhappy Thinking its time for an oil cooler

I think its time to change my oil cooler. Lately i have noticed my temps are getting higher and higher. Last night coming home from the sand dunes pulling a 15 foot trailer with my rzr on it. My oil temp was 215 and coolant was 192. it was about 50 degrees and on flat ground with no wind. I can hit a 15 -20 degree delta empty going down the highway at 70. It doesnt stay very long but it still worries me that the cooler is going out. I lost the egr cooler somewhere a long time ago so i can rule that out. I also just installed a coolant filter.

Do you guys thinks it would be wise to go ahead and replace the cooler and flush and fill back up with elc coolant? Who has the best cooler out there? I wish i had the funds for the bulletproof kit but thats out of the question.

Flush with chemicals before you swap oil coolers or else you will clog the new cooler. Follow the guide posted in the 6.0 tech section. It answers alot of flushing questions.

Dorman tends to be cheap, Chinese stuff. I'd probably not go that route because getting to the cooler looks to be a PITA.

dont go with oem cooler I had headstuds, full delete and new oil cooler installed 3 weeks ago and I did a vc-9 flush for about an hr. then ran water for 3 days and drained and replaced with distilled water and did the headwork and some crap was still left in there now im seeing 9 delta just cruising.

do the bpd oil cooler kit if you can afford.

Im saving for it now because my 2nd oil cooler is showing signs but still within spec.

192 ect and 201 eot crusing 65 on highway....

click on my name and find the thread with "Nighmare in the heading"

Truck nightmare or am i just to being dumb?

OEM Oil cooler is what I'd do if Bulletproof is too much.

Before changing it flush with restore and restore plus (follow instructions as advised above) and then run coolant filter for several hundred miles, changing out your filter at least twice (three times is better) to get the crap out of your system. The left over crap is what clogs the oil cooler. Once you have the new cooler run CAT EC-1 rated coolant and you shouldn't have more problems.

An update on my problem. Added a little coolant to the degas tank the other day. Come to find out my sinister coolant filter is leaking around the crrimped fitting that gouse to the de gas tank. Anyway i decided to take it out for a spin. Got her up to normal operating temp and let her loose. 7 miles at 110 mph. Yes you read that right 7 miles at 110 mph! That is one reason I love living in western kansas. I figured she is going to blow or hold strong. MY temps never got more than 7 degrees apart. So do you guys think my extreme temp differences were a fluke or should i still be worried?

you need to find a good tll hill (in Kansas?) and crank ac on hi and floor it up in 3rd gear and see what she says but 7 degrees sounds good man. your coolant temp could of risen because of leak.
