I want to change the clutch fan on my 2005 Duramax diesel Silverado, to two S-blade eletric fans. Would that be a bad th
ing to do. The fans that I found are made by GM for my year in pickup,
Is it bad to change the clutch fan to two eletrics from GM on a deisel?
I drive a diesel pick up as well, albe
it an 05' F-250. I belong to a fantastic online group called %26quot;oilburners.
net%26quot;. They have assisted me with several technical questions related to my pick-up and I believe they'll be happy to help you too. These guys are professional diesel techs, die hard diesel owners and builders and they address performance and daily driving issues all the time. I trust them completely. I would definitely not take advice from anyone who thinks your Duramax is worth 5 grand. How about tripling that amount. If you can't get a good answer from your GM techs at the dealership of your choice, bounce your question off of the oilburners bunch. They'll talk to you like you're an equal...no superiority crap and they'll genuinely want to help. Free, easy...great bunch of folks.
Best wishes and for goodness sake...don't blow that truck up. Get some good answers that you trust.

sould like a plan to me, just be sure to wire them to be thermostatically controlled.
it will be OK as long as you have them hooked into a temperature sensor so they come on when needed most electric fans are computer controlled where it monitors the coolant temp and activates a relay turning the fans on around 200 220 degrees how are you going to accomplish this with your truck
I WOULD NOT DO IT. There is NO WAY those fans will even come CLOSE to the air flow from a Mechanical fan. If you tow ANYTHING, you will get heat up at Approx $5000 engine.
Not to mention the transmission and AIR TO AIR intercooler for the turbo, which the loss of air flow will further add to heat in the engine, causing lugging and more heat,,not to mention loss of HP via no air flow through the intercooler.
DON'T DO THIS!!
yes it can be done but its a pain in the **** to hook up, and then you have to hope it works right
Nothing at all wrong with that. In fact, you may see a little more power as a result. Though in the end both consume the same energy (in theory), the power to drive the electric fans will be derived constantly and evenly (with the charging if the battery). The same cannot be said for the belt driven clutch fans. A back up (redundant) temp gage would be my only suggestion.
you want to change a clutch fane to a elec fan,,i would keep the same clutch is better and safer the a elect fan..
It shouldn't be provided how you set them up. If done correctly the electric should be more efficient than the clutch. Plus the clutch tends to not engage as well with age resulting in hotter engine coolant temps.
Most electric fan configurations are push / pull design where one fan helps the other by pushing the air through the condenser / radiator assisting the fan on the back side of the radiator. You will need to use temperature sensors to cycle the fans as needed, otherwise they will have to run continuously, which voids the efficiency. Typical set ups have a temp sensor (basically a switch that grounds when hot enough) is tied to a relay. When the sensor grounds the relay closes and powers the fan(s) to run until the coolant is cold enough for the sensor to open.
One other thing to keep in mind is the shroud. The current set up has the shroud close to the clutch fan so all air passes through that one hole and pulls over the entire radiator. If you don't use a shroud (hopefully came with electric fans or a trip to the junk yard might help) then the air flow may not cover the entire radiator resulting in hot spots and early wear / failure.
Hope this helps and good luck.
