I've purchased a '51 half-ton Chevy pickup with a '56 235 pickup engine in it. My cooling fan is too close to my radiator. I assume the water pump shaft has already been shortened as the pulley lines up with the generator pulley. I found I had to bend the fan blades to keep them from hitting anything and now I'm concerned that they are not balanced and may cause engine damage. Do I need to move my radiator forward to correct this problem ?
Thanks

He bent his fan blades and has been driving it for over a year and has had no problems with vibrations,noises or cooling. But on the other hand we've done some pretty shade tree things around here that has had some bad results and some that has not had bad results but it just was'nt the right way to do it,so I would definetly get more info on that sitution.

You can make one or buy one from most truck vendors on this site. Getting the correct fan is another issue. I had to use a whittled down fan which was ok until the hot summer months. So I added an electric fan in front of the radiator. | | |

With the adapter the fan will be in the right place and you can use your old fan blade with out altering it. You can buy the adapters from several of the old truck suppliers or on ebay. | | |

So close that I cannot get a fan belt by. I worry that I am too close but with a good set of motor mounts and no hot rodding of it I am hoping it will be okay. I cannot say I recommend having it that way and also do not recommend moving the rad foreward. | | |
