Suprakeith Posted May 20, 2018 Share Posted May 20, 2018 Am some advice please as have fitted ATI crank damper to engine build and was doing finishing touches and was planning on still running stock radiator cooling fan, but when fitted fan noticed it was catching on the 3 bolts still out from crank pulley. Question is does anyone run stock fan with ATI crank damper? Or is it a case of when fit crank damper have to then fit electric cooling fans? If fitting electric fans can anyone recommend good kit too use please and best way to wire in fans please? Quote Link to comment Share on other sites More sharing options...

Suprakeith Posted May 20, 2018 Author Share Posted May 20, 2018 I dont have my car atm so cant take any pics. But i run the ati damper with stock cooling fan Did you have to put and spacers on the stock fan? And it’s an SRD alloy radiator so bigger than stock but that shouldn’t affect fan at all.

Gpro Posted May 20, 2018 Share Posted May 20, 2018 I run the ATI damper with a stock radiator fan and have no issues. Are you using the gates belt? (http://realstreetperformance.com/Products/Gates/Gates-Serpentine-Belt-for-ATI-918562-Harmonic-Dampener-2JZ.html). What 3 bolts is it catching on? sorry didn't quite understand that bit. The only difference between mine and users is that I still have the aircon pump. Quote Link to comment Share on other sites More sharing options...
scotty_1987 Posted May 20, 2018 Share Posted May 20, 2018 Ahh yeah you are right. Shouldnt have an affect on the fan. The only things i can think it is then is either the fan is sitting to close to the engine. Not sure how thatd be possible tho. Or your crank pulley is sat too far out? Is the pulley definatley seated correctly? I had to get mine machined slightly fit right Quote Link to comment Share on other sites More sharing options...

If you look at picture it’s the 3 bolts protruding from the crank damper, catching on my fan blades. The only difference I can think off is, could be because mine is an N/A block and head?? Does anyone know if that would make difference? Quote Link to comment Share on other sites More sharing options...

I had to get mine machined slightly fit right The pulley does look correct but it could be worth taking it off and double checking to be sure, it is a brand new crank aswell so maybe that could be causing it to not sit perfectly right Quote Link to comment Share on other sites More sharing options...

My fan is nowhere near the crank pulley bolts, so something isn't right on yours? Quote Link to comment Share on other sites More sharing options...
scotty_1987 Posted May 20, 2018 Share Posted May 20, 2018 (edited) Yeah im pretty sure mine sits no where near the blades You are right about the n/a being different.

Thank you for taking picture, I now have funny feeling that my crank damper isn’t seated properly which now means trying to take the thing off again, which is going to be nightmare plus have just filled all my fluids today. Been looking online and some sites saying about a tolerance guide with the ATI crank pulley before fitting but just checked my box it came in and have no tolerance settings for crank key way.

Found this on another forum [ATTACH=CONFIG]227219[/ATTACH] You are a star [emoji106][emoji106], I have been searching and worrying that the damper wasn’t fitted right, thinking I would have to remove it all again. Any chance you could send us that link be nice read whole thread if there is anymore. So looks like could just need tt fan then. Quote Link to comment Share on other sites More sharing options...
scotty_1987 Posted May 20, 2018 Share Posted May 20, 2018 Link i have added to above post. Theres a few things about it on supraforums.com some people have trimmed the fan. Some people havent put the 3 bolts in the front of the damper. Surely makes sense to just change the fan lol some strange people. No worries btw. Can be annoying to find the right answers sometimes Quote Link to comment Share on other sites More sharing options...

Can be annoying to find the right answers sometimes Thank you so much, you have been so helpful. I have just been reading that people remove the 3 torx bolts but I will go for the change fan option I think. Just can’t believe that there is so little information about fitting the ATI to an na engine, at lease now I can start engine as planned next weekend and search out new TT fan. Thanks again for helping me out this been bugging me most of day thinking if I had done something wrong Quote Link to comment Share on other sites More sharing options...

Jamie ran the stock viscous fan on the Black Beast when it was 1300hp, therefore I would leave the stock fan with its shroud in place Quote Link to comment Share on other sites More sharing options...
