Oil Cooler Bypass Valve/ Thermostat Stuck
 

Hey Guys,

I am trying to remove the oil cooler bypass valve/ thermostat out of my oil cooler, but I can't seem to pull it out. I thought once the nut was removed that holds in the oil cooler it would just fall out. But its stuck in there, have any of you guys experienced this yet? Or have any tips on getting it out? I want to remove it to get the oil cooler cleaned and pressure tested.

Thanks,
Ernie
