I need the head bolt tighting sequence for a 73 250. If anyone could scan and e-mail me a copy . I would be very thankful. Thanks Russ
Russs I don't have a way to scan, but here is the sequence, should be 14 bolts total torqued to 70-75 ft.lbs. Number 1 being the fourth bolt from either end. 13 8 4 1 5 9 12 14 7 3 2 6 10 11 There ya go ...
Most engine builders torque in sections. Ex. if you are going to 75lbs. Use the sequence you asked for and start getting them to say, 45lbs first, then 60lbs, and lastly 75. Seth
I got the botls tight and got it up and running. 8 hrs to change head gasket, changed lifters, and new thermstat. I torqued the head bolts in two steps 55 lbs, then 75 lbs. Everything seams ok. I have some air trapped in the coolant system, so I'm going to leave the rad cap loose for a few days to see if I can get the trapped air out. Thanks to everyone here. You guys Rock. Russ
