Welcome to the forum .


You have to disconnect the oil cooler lines on the left side of the radiator in order to remove the fan . Remove the serpentine belt and tensioner , idler pulley and the alternator .Then the power steering pump in order to get to the thermostat . I would also do the alternator bracket gasket while you're that deep into it . Costs 10 bucks for the gasket .

Also get some chf 11s hydraulic fluid because you have to disconnect the inlet hose in order to get the power steering pump out of the way .

Here is a picture you can see the thermostat with the alternator and P.S pump out of the way .

What are the the signs that oil cooler thermostat needs to be replaced? Thanks

From what I remember when I did my bracket gasket -
I pulled that thing apart to reseal. I know everyone calls it a thermostat, but it looks more like a pressure dampener on the inside (equalizes the pressure between inlet and outlet).

@A B able truck yes I see that it is located on the side of my radiator by the oil cooler black plastic piece of course and is small about 21/2 to 3 inches long...

@solotallboy my water pump was bad after a technician did the pump test and said I needed a new water pump which i did myself and also he diagnosed that I needed an oil cooler thermostat.he did not want to show or tell me exactly what it was and hit with a price of 2500$ bucks if he did the job and will take 6hours.. Sorry Charlie I went to you tube and found this guy named Steve aka "diy e65 e66".. Show you step by step to do the water pump to me it was easy but bummer to get that last bolt off under the AC belt wheel..job well done my friend

I think you're talking about the transmission oil thermostat
