Coolant system redo/upgrade options?
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.

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.


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!
Do you remember size? or by any chance have the parts numbers handy?
thanks
