It is a common error to think that you can clean out a 40 year old oil cooler with
solvent. Over the years the entire inside of the cooler will be covered with
caked and hard oil residue, and no amount of solvent will remove it. The only
way to do this is to go to a specialist company with big industrial ultrasonic
cleaners which vibrate the oil cooler and these parts will then become dislodged.
After that you then use your solvent. There is no other way that will
work! Richard

Is this a standard size oil cooler for Yak 50? My oil temp. is always in the red.
Removed, soaked in cleaner 2 days, pumped cleaner until showing clear. No change.

But, is this a standard size or is there a larger one. I have had comments saying
both.. And is the current size sufficient enough to cool the oil?
