GA 55 advice
by: Mike

check the 2 easy things: is oil cooler clean? is oil level low?

if those 2 are fine it is likely caused by a faulty thermostat valve

when the unit trips on high temp feel the hose fittings going into and out of oil cooler, if the outlet fitting is ambient temp your thermostat valve has failed

it’s a 5 minute job to replace
