posted this in early 99 section didnt get any responses. ill try it here. need a little insight. i have a early 99 f350 dually, 5in exhaust, diy intake.and a gt tuner running on tow setting. was towing my bronco this weekend in tx outside temp 95- 100 degrees outside. noticed my oil temp getting up to 240 degrees. engine temp running normal temp. had replaced the oil cooler a year ago. when i bought this truck the cooling sys was nasty had eaten thru the frt cover.i flushed the system several times. after repl cover. yall think that cooler is clogged up again maybe? that temp seems very high. normal driving i only remember seeing 212 degrees. update hadnt heard my clutch fan really come on lately. so i chgd it. then it rained today lowered outside temps to around 80. oil temp running 65-70 mph oil temp around 210 on drive home.
