do you know what year, make and models of thermostat fit in this housing?
also what is the lowest temp thermostat there is for chevys?
thanks

For a pusher fan you're going to want a fan without a shroud. As for fitting two pullers, there's no way. The biggest you could go with dual fans is 12". Well, MAYBE 14" if you staggered them, but when I had staggered 12s there was little extra room.

As for thermostat, I went with a 180. My truck has been idling in the yard for about half an hour and she is sitting dead at 180 right now. There's a lot of controversy as to where these trucks enter closed loop. Personally, I wouldn't go below a 170 thermostat. I haven't decided yet if I'm going to stick with the 180 or go to a 170 just because of how much I tow.

have a look at the inline thermo mod and associated write-ups. lots of good info in them.

lowest temp may not be best, resulting in poor performance and bad gas mileage. I think most folks go with a 180. these engines / ECM's are a little finnicky- not too bad, but a bit.

Here are some pictures of my current setup. You can see I've also got a temp gauge added which is where I have been bleeding, but its a bad spot. Instead of adding another piece in line, I'm going to drill and tap the actual thermostat housing and put a little bolt or something so I can bleed it there.

Make sure you use a brass impeller water pump. For whatever reason, they are the best for this truck.

funny you said that, I was thinking today if someone has any recommendations about the pumps...
I know they come with a lifetime warranty but that is not the main concern here: PERFORMANCE!!!
If We are sending all this money, I will make sure we get the best we can afford!

I'm trying to find the specs on our radiator's hoses ( don't know our ID) and really will like to order the housing asap.
Do you remember size? or by any chance have the parts numbers handy?
thanks

Check back in and let us know how the fan works for you. My Flex-a-lite 180 has proven inadequate in traffic with A/C on. I am on the fence between trying the ford or going back to the clutch fan.
