ok i have the 4.0 out of an explorer. i keep getting rocks, sticks and other things going through my radiator when i go desert riding with friends. so in the case i want to move it to the rear.now i have done some research and found copper tubing the way to go and that i need an bleeder valve in he system. but my questions are should the fans push or pull the air through the radiator and will the stock pump do all the work or do i need to get another pump. now i read copper tubing was the way to go but dont know the size could not find the answer.

 

Who do you have to put a gun up to get help from this form. This place sucks

 

Sometimes it takes more then 23 hours for people to respond. Look that stuff up on a baja or prerunner truck site. Not to many of those guys on here. Hense the "long" delay in respond time

 

Dude I have post that are months old and no help so 23 hr or a month nothing happens.

 

It depends on the section also.

As mentioned, there is only 3/4 prerunner guys on this site. Check out deserrangersdotcom. The site is full of these threads.

 

Let me get this straight. You come on here to ask us about a problem that you cant figure out, and we are the ones who suck? Man all your doing is putting a radiator in a bed, its not rocket science.

Give it some thought, im sure you can figure it out. Then YOU can tell us how to do it and earn the right to say we suck.

Oh btw, i have the answers you need. Good Luck

 

lol

And that folks is a good example of why you never want to burn bridges!

The size tubing you will need is based on the size hoses you use to get to the tubing.

Where are you going to buy copper that size? I ran boat exhaust tubing the my radiator in the rear.

Also make the fans pull, it always works better as a pull than a push.

 

The better question is, can you afford it? New pipe is going to run you $300-$400. And people don't sell used copper for cheap.

**hint** whether you go push or pull, when driving forward what way is the air flowing? Make the fan flow the same direction

 

no air flow behind the truck... lol

I agree, no way im buying copper tubing. Ill use something else.

 

Yes there is. Ever gone down the highway and have something fly out of the bed? Air flow..

As your driving a little vaccum is somewhat created that pulls air towards the tailgate. If you have your fan pulling/pushing towards the cab, your actually fighting against it, and will not flow as well.

He's driving fast out in the desert, on the rocks i can see it not making a difference. Even in mud you want it near the cab pulling to the rear. Less mud and dirt will get sucked in.

 

There isnt enough air moving to cool the radiator on its own. So in my opinion its not much air.

 

I agree. But it matters which way the fan is directing the air. That little bit makes a huge difference. I didn't want to tell this to the OP because he was being a doucher.
