I have a 53 1/2 ton and installed what I thought was 55 235 engine. Minimal clearance between fan and radiator. Hit a bump and fan tip cut into radiator. Unable to locate or see casting number on block but another number behind distributor ends " 54Z " so assuming I have a 54..Is there a difference between a car and truck water pump? THanks, Scott | | | | | Joined: Feb 2004 Posts: 29,742 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,742 | The pump needs to be modified by pushing the fan hub back with a hydraulic press and cutting the shaft off a little. Some of the resto-ripoff places sell modified pumps for outrageous prices to people who can't do the press job themselves.
Once you get the fan and pulley pushed back to clear the radiator, you'll find that the fan will try to hit the harmonic balancer and it will be located too low to cool the engine properly. The fix is to purchase a pump relocation plate that allows the 54 and earlier water pump to be used on the post-55 block. That will put the fan in the proper location to cool properly, and fit far enough back to stay out of the radiator.

I was giving information about the later model 55 engine with the water pump that fits into a hole in the front of the block.
