alexideways Posted November 14, 2006 Share Posted November 14, 2006 ...but I think my Master Handbook or 1001 circuits has a design for that. Where did you buy these books, especially the second one? 1001 circuits, look's exiting. Quote Link to comment Share on other sites More sharing options...
naviathan Posted November 14, 2006 Share Posted November 14, 2006 "The Master Handbook of 1001 Functional Circuits" is the full title IIRC. It was given to me by an old friend when I was in the Army. I believe you can still get the on amazon used, but not new anymore. Quote Link to comment Share on other sites More sharing options...
naviathan Posted November 14, 2006 Share Posted November 14, 2006 Not sure if that was meant to be sarcastic or not, but I just noticed an error in my wording. Connect the controller to a constant hot so it stays running until the engine cools down. Quote Link to comment Share on other sites More sharing options...
alexideways Posted November 14, 2006 Share Posted November 14, 2006 Not sure if that was meant to be sarcastic or not... If what, was meant to be sarcastic? Anyways, no srcasme on my parts, sorry if I made you feel that way. Quote Link to comment Share on other sites More sharing options...
Zmanco Posted November 14, 2006 Share Posted November 14, 2006 Keep in mind that if you use a controller with the sensor that installs in the radiator (whether in the coolant or in between the fins), wiring it to run the fan after turning the engine off will only keep the fan running until the radiator goes below the turn-off temp. It will have very little impact on cooling the rest of the engine. I don't think you will harm anything with this approach, but I don't think it will make much of a difference either. If the sensor is mounted somewhere on the heads, then I think there is much more benefit, but without an electric coolant pump to keep the coolant circulating, the flow due to convection could take a long time to get things cooled down so the fan shuts off. I'm not saying this will always happen, but on a hot day after driving in stop/go traffic, I could see this taking 15+ minutes. If your battery is in good shape, probably no harm. If it's marginal, might not be a good idea. 1 Quote Link to comment Share on other sites More sharing options...

Guest Mike Posted November 14, 2006 Share Posted November 14, 2006 Zmanco... My thoughts exactly. An elect H2O pump AND elect. fan(s) connected to full-time hot will cool the car after shut-down... probably the BEST benefit of going all elect. Keep in mind that if you use a controller with the sensor that installs in the radiator (whether in the coolant or in between the fins), wiring it to run the fan after turning the engine off will only keep the fan running until the radiator goes below the turn-off temp.

naviathan Posted November 14, 2006 Share Posted November 14, 2006 Oh sorry about that, I thought hit the quote in reply. I meant mikes comment on keeping the water pump running as well. Probably not, but I wasn't sure. No offense taken either way. Just wanted to clarify that I didn't mean the fan should run constantly, only until it cools off the engine.

Guest Mike Posted November 14, 2006 Share Posted November 14, 2006 naviathan... Nope, no sarcasm intended. I agree with you and only meant that an electric H2O pump, combined with an electric fan is the ulitimate cooling package when consideration is given to continued cooling after engine shut-off. I'm sorry if my post seemed sarcastic... completely unintentional... though I am sarcastic from time-to-time:-D Quote Link to comment Share on other sites More sharing options...

rztmartini Posted November 14, 2006 Share Posted November 14, 2006 guys, they already have a timer to cool things down. just get a turbo timer and have the fan run whilst the timer is counting down. i think it would be cheaper than an electric h2o pump and would work the same way?

Zmanco Posted November 14, 2006 Share Posted November 14, 2006 i think it would be cheaper than an electric h2o pump and would work the same way?No, with an electric water pump the coolant continues to circulate through the engine and carry heat to the radiator to be cooled by the fan. Without the electric pump, there is very little coolant flow (just a little due to convection) and so you don't get as much benefit. Quote Link to comment Share on other sites More sharing options...
rztmartini Posted November 15, 2006 Share Posted November 15, 2006 with the turbo timer the engine is still running so the water pump is still moving water so it will work the same way. Quote Link to comment Share on other sites More sharing options...
naviathan Posted November 15, 2006 Share Posted November 15, 2006 Ummm, you're not understanding, we don't want to engine to stay running, just the cooling system. Quote Link to comment Share on other sites More sharing options...
Guest Mike Posted November 15, 2006 Share Posted November 15, 2006 What he said... EDIT: BTW, I just ordered electric fans and pump. These will be set up to run as long as it takes to cool the engine to 160 degrees after shut-down. Quote Link to comment Share on other sites More sharing options...

JSM Posted November 16, 2006 Author Share Posted November 16, 2006 Picked up a Hayden Adjustable Controler from Pep Boys good from 160 - 210 @ 30AMPs. $44.99. Couldn't find a Flexalite, even though Napa suppossedly sells them. Looked all over Orlando. Quote Link to comment Share on other sites More sharing options...
