water pump to radiator clearance?

[opelwasp]

I plan to install an electric fan in the GT. What is the amount of room I have to work with between the radiator and the water pump pulley? I would normally measure it myself but my engine is in pieces all over the garage right now.3 in? 4in?

I just finished installing a 14" Permacool Electric Fan in my '73 GT. I mounted it in front of the radiator as a pusher fan, exactly like the instructions given by Jimsky (Thanks big time Jimsky!). I looked at a puller installation, but there only looks to be a couple of inches between the fan pulley and the radiator, and I didn't want any clearance problems. Besides, w/ the fan in front of the radiator, the engine compartment looks cleaner IMHO. It was a lot of work, though, as you have to cut away part of the radiator support crossmember to get clearance for the fan (a little scary to cut away at the original metalwork). But, once I finished it, and tested it out, watching that fan turn on and off on it's own was a great feeling (I bought the car w/ no fan at all, so I couldn't drive it until this little project was done).

My '73 is 2 7/8" from the radiator fins to the front of the belt sheave on the water pump. I can't see the actual front of the pulley hub, since the stock fan partially covers it. Maybe you can measure from your pulley hub to the front of the sheave and do some interpolation.

Also, I am running an ARA air conditioner with a double crankshaft pully and so I think that my water pump (and alternator) pulleys have ~1/2" spacers under them to move them forward to run off the front belt. So, a stock GT should have this much more room between the radiator and WP pulley than mine does.

Sorry to not be more precise, but I just can't get a closer measure without doing some dismantling. Hope this helps!
