If I go into a parts house and say I want a clutch and fan assembly for a 1978 f250 351M with air conditioning, will they have them? And is it true that all A/C 351M trucks had clutch fans?
Thanks

Don't crush them, restore them!

 

Weldman,
I don't know about all, but my 77 F-150 with a 351M and A/C had a clutch fan. My 78 without A/C does not however.
Hope this helps,
Terry

 

Hi,

You may want to look at page 9 of this archive. There I posted a similar question and had lots of responses. I am not sure if the parts jobbers sell those clutches, but it's worth asking.

Good luck, hope the old post helps,

Mine originally came with a clutch fan. When it quit working I went to Pep Boys and got a Cool King R/V unit and it worked great. Cost a couple of horse power and about $55.00 at the time.
