I am installing a puller fan, with a shroud on my truck. Where is the best placement of the fan, top, center or bottom of the radiator, or does it make a difference. Lynn

MOST FANS ARE PLACED AT THE TOP ONLY BECAUSE THEY WILL NOT CLEAR THE PULLEYS DOWN LOWER.

Gene Riffe [ View ] [ Email ] [ Blogs ] [ Car Ads ] Saint Petersburg, Florida   Posted by ronhotrod  -  03/06/2008 08:21 PM hotrodgene is correct in that ALL the hot water from the engine enters the radiator at the upper hose. Therefore you need to begin the cooling as soon as posible . as the air is pulled thru your radiator is cools the hottest water first, progressively getting cooler as it travels downward in the radiator. Finally the lowed temp water goes back into the block to absorb more heat and the process starts all over again. So put the fan as close to the top as posible ronhotrod [ View ] [ Email ] [ Blogs ] [ Car Ads ] Mount washington, Kentucky Charter Member since July 2001   Posted by Rodrunner  -  03/06/2008 08:37 PM I agree with Dixie....Center and get as large as one will fit....16 or 17 inch fan, try to cover as much area as possible...Looks like you have plenty of room ... Rodrunner [ View ] [ Email ] [ Blogs ] [ Car Ads ] na, Tennessee   Posted by JAWS  -  03/06/2008 09:57 PM Ideally the fan shroud should cover the entire core so the fan can move air across it when sitting. As you know when moving this is happening anyway and then the entire radiator is working as it was intended. As was stated previously, the hot water passes the Thermostat and into the radiator through the upper hose on most applications. So it makes sense to start cooling there as soon as you can. If the fan only covers part of the core, then that is the only part that is cooling efficiently.

APLUS [ View ] [ Email ] [ Blogs ] [ Car Ads ] Austin, Texas   Posted by 30 A pickup  -  03/07/2008 05:29 AM I was thinking top also, just wanted to confirm sure. It will have a shroud 5/8" from the fins, so air SHOULD be moving over the entire radiator anyway. It is a 16" fan also.

How many cfm? 2300 or more I hope ? 16" ?. Controlled by ? Check the load on directions...how many amps at max? Use correct wire size thru out. #14 AWG minimum. DO NOT ground to radiator or sheet metal. Take ground back to grounding block. Anchor on radiator metal sides only..left and right verticles. I use a 5 blade when it will fit. Congrats on picking a puller and NOT a pusher.

Cools great. I have had 3 cooling componet fans over the years and all mounted at the top. Why let the hot water go back into the block.
