I have picked up a few good quality $ used oil coolers over the years. Each guy said they were good and just changed out due to new modifactions to the car. They look perfect, but used. I am now thinking of installing one on my car.
Question.
Is it safe?
Is there a way to clean them/insure nothing is bad on the inside.
This would save me about 280.00 dollars if I could used it.
Thanks,
Ed

Take them to a good radiator shop, let them vat them and clean them and pressure check them.

Cheap insurance.

cars and such...

i cleaned out mine with some carb cleaner (about half a can worth)... let it dry, rinsed out.. took it to a local shop and had it tested... they probably will do it for free

This topic came up many times when I was into Porsches. Most people in the Porsche community recommended having them sent out to a shop that could ultrasonically clean them to remove any metal shavings that cleaning with carb cleaner or another solvent may not knock loose.
