Hey guys,

Has anyone had their oil coolers sonic cleanned?

I have 3 FC oil coolers that have been cleanned by a shop recommened by mazdatrix. All were cleanned at different times and stored to be used later on my end.

I shook one side to side long wise and you can hear something shake inside. I tested this with my other 2 clean oil coolers and it did the same things. Is this normal? or are they really not clean? I can hear the noise on both sides.

Well I went ahead and installed one but what do you guys think?

sounds like a check valve to keep oil pressure up at startup

or the thermostat inside of it fell apart.

Took out the thermostat and is in good condition.



Is weird, is like it moves inside the fin/tube area left to right when shook.



Nothing came out when I shook it and took the thermostat out.

weird, maybe you should check and make sure it gets hot?
