Winston Wolf Posted December 1, 2010 Share Posted December 1, 2010 Long. It is not the neck that constitutes long or short. It is the dimension from the pulley flange to the engine block flange. Long is 7" and short is 5-5/8". Quote Link to comment Share on other sites More sharing options...
kc8oye Posted December 1, 2010 Share Posted December 1, 2010 if you can get your fingers between the water pump and the timing cover, it's a long. Â if you can't.. it's a short. Â Â 'short' water pump had the accessories mounted to the exhaust manifold bolts with brackets. Â the 'long' water pump moved the accessory mounts to the front of the cylinder heads. IIRC 1969 was the first year of the long water pump design. Quote Link to comment Share on other sites More sharing options...

Andy's Auto Posted December 1, 2010 Share Posted December 1, 2010 The only thing you will find a short pump on in 71 is a Vette. Quote Link to comment Share on other sites More sharing options...

kc8oye Posted December 2, 2010 Share Posted December 2, 2010 my chevy book says the vettes have their own unique water pump that's stort of a 'medium' Â 68 and earlier small blocks had the short water pump (alternator on the driver's side) Quote Link to comment Share on other sites More sharing options...
allchevy Posted December 2, 2010 Share Posted December 2, 2010 HEY! I got a Vette! Quote Link to comment Share on other sites More sharing options...
maddmann313 Posted December 5, 2010 Share Posted December 5, 2010 ummm I'm having some trouble getting my water pump off... Can someone tell me the process you go thru to take it off... It's a 72 with factory a/c! Thanks Quote Link to comment Share on other sites More sharing options...
72-CLASSIC_RIDE Posted December 5, 2010 Share Posted December 5, 2010 Here is a couple shots of the water pump exposed. Not sure what engine your running but this ia a Big Block 402 CI. Make sure all WP bolts have been removed along with Fan blade, Pulley, Belts, Hoses. May need to tap WP with rubber mallet to break loose from engine. Make sure Alternator bracket is clear & that should be it! Â Â If I missed anything, someone will chime in to correct me. Hope this does it for you. Â Have a GREAT day......

kc8oye Posted December 5, 2010 Share Posted December 5, 2010 pull the four bolts and lean down on it.. it will pop off. Quote Link to comment Share on other sites More sharing options...
maddmann313 Posted December 5, 2010 Share Posted December 5, 2010 YEa Kenny that's what I said I thought it was just four bolts the hoses and come right off but there are so many brackets holding this thing on it unbeliveable Quote Link to comment Share on other sites More sharing options...
Blake350 Posted December 6, 2010 Share Posted December 6, 2010 Yes,it is just for bolts and two hoses-once you get everything else out of the way!!-just like with anything else,proceed slowly,note how everything came apart so you can reverse it later without making yourself crazy,and keep track of all the nuts and bolts. Just 'crack' the pump bolts loose carefully in case they are weak(a sheared bolt here could be a horror show),and (if I remember correctly)two pump bolts are into coolant-make sure they bare cleaned and resealed before reassembly-have fun!!

maddmann313 Posted December 6, 2010 Share Posted December 6, 2010 I had only 3 of the blots out I thought all 4 were out!! But I just got done replacing it! Thanks Quote Link to comment Share on other sites More sharing options...
wallaby Posted December 6, 2010 Share Posted December 6, 2010 Well at least you found the problem before you started adding bionic force. I had a friend in high school that forgot to remove the series of head bolts that are hidden under the exhaust manifold...he used a big bar inserted into an intake port to pry that head off the engine. He actualy broke the cylinder head into two pieces lengthwise! Quote Link to comment Share on other sites More sharing options...
