Get the Best performance from your Trailblazer SS LS1 Efan conversion

[@husseinfshikat9818]

Is it possible to install an electric radiator fan instead of the clutch of a 2004 Chevrolet Blazer 4.2 L, and what are the numbers on the BCM? Many thanks and appreciation to you.

[@scottwilliams2968]

Where do you find the info on where to place the pins in the ECM for the fan? Going electric in my 03 trailblazer and can't find the pin info anywhere...

Hey Ralph nice video thanks for sharing your ideas, I still haven't had my fins installed yet but did help a friend with some ideas on his installation and added rubber door mounding weather seal around the edge of the fan purchased from Ebay this also took up the gap and insulated the fan shroud from the radiator but I will also add this for a better seal Thanks!!!!

[@codybeauchamp5734]

Did adding the foam tape to fill the gap make a big difference for you? I just put ls1 fans on mine and they arent xooling quite as much as i would like.

[@RalphsGarage]

Yes the foam made a massive difference.

[@codybeauchamp5734]

@@RalphsGarage awesome man thanks, I'll pull them back off and add the foam maybe next week

Love the videos bud!!!

What about the wiring how you wire up the fans

[@RalphsGarage]

I did an indepth video that covers all that. kzbin.info/www/bejne/jp3HYq2Ho7p3pM0

Hey man, Im thinking of doing the LS1 fan conversion. Would you think using 2 in weather stripping would be too much? It would definitely touch the radiator but would the radiator eat it up in time? Let me know what you think? Thanx

[@RalphsGarage]

It depends on the gap you have. I have. Pretty large gap on mine and I'm willing to bet you'll have almost he same gap.

Thank you!!!!

[@nickscull6482]

I'm gonna check that out Ihave some e fans and I'm having the same issue

[@papabear8908]

I have been on the fence about this so I have an honest question. Did you really gain any hp or great gains (benefits) from this besides just keeping your engine cooler?

[@RalphsGarage]

Yes ditching the engine driven fan and going to electric definitely frees up horse power.

[@sanosuke2999]

Is the TrailBlazer SS staying cool in stop and go traffic now?

[@RalphsGarage]

Yes but I was only have problems last summer on very hot days. It's not hot enough to know for sure yet but with how large the gap was between the shroud and the radiator it will definitely be much better now.

@@RalphsGarage Thanks for the update!

Hi Ralph been watching you videos and I just purchased a 2008 TBSS and I’m from New Jersey as well if there is someway I could reach you for some personal questions that’d be awesome

[@mjflit]

Did this end up working? I've been debating on using ls1 efans or one of the pricey spal setups.

[@1964rmcc]

Ralph keep us posted on the Temps or any changes pleas

[@RalphsGarage]

Temps have been solid no problems when it was over 90 and I got stuck in traffic for 45 minutes, even had the AC blowing ice cold.

[@1964rmcc]
