Crossflow coolant cap

[Rettedm]

Can anyone give me the part number for a cross flow coolant cap? I have a Motorcraft 100 and it seems too short to seal and overflow tank is always filling up. '91 1700.

 

Thanks, Dave

Sounds like you have the right cap. The Motorcraft 100 is what I just pulled off my 1600 crossflow and replaced with a Pep Boys (Stant?) 13lb cap. Seems to work, though I still seem to be running a bit hot, which could be any number of things. Will be checking the overflow and the coolant level this weekend and will know for sure. I would think you could probably go 16lbs without any problems. That may solve your overflow issues.

While we are on the subject of Crossflow cooling systems what temp thermostats do you guys run ?
