Any recommendation on whether to use aftermarket or OEM on both thermostat and ICP sensor for 95 f250 4x4 would be appreciated.

Local Ford-house wants 237 for an ICP sensor and 45 for a thermostat. I bought an aftermarket thermostat at O'Reilly about a year ago and don't know if it works correctly; gauge needle moves only about 3/8 of the way toward center when running, so I thought I'd replace it just in case

 

I got both mine at Riffraff.

 

Here is where I got my Motorcraft thermostat, $31

Motorcraft Thermostat 94-95 - Riffraff Diesel Performance

They also have the Motorcraft ICP sensor for $137

Injection Control Pressure ICP Sensor 94-96

 

appreciate it. i saw where old bird recommended using fleet charge coolant on another link. I've never changed my coolant myself but plan to do it with this other stuff. I assume you're mixing the coolant with distilled water to get a mixture of 7.25 gallons half distilled water/ half coolant.

 

That is correct!

 

thank you for the help
