I'm curious about something that I have never seen discussed around here - the gains to be had by flushing an oil cooler. One of our airplanes is closing in on 1900 hours on the oil cooler, and while it might just be the insanely high ambient temps we are having this summer, the oil is running a bit warmer than usual - could it be we might want to flush the cooler to see if there is an improvement?
I talked with a fellow at Oshkosh from Pacific Coolers, and he said that they advise a flush every 500 hours. Of course, he was selling flushes....so I am interested if anyone here has had theirs flushed, and if so, did you notice an improvement in oil temps? I've put thousands of hours on oil coolers in my planes over the years - never had one serviced.
