Intercooler helping hand

A intercooler gives approx 10% power increase to a diesel so i don't think the gains you might get a low speed pulling air through the intercooler to make it more efficient would warrant the expense & extra stuff you need to fit to the engine

The more stuff you add to a vehicle (unless needed) the less reliable it will be

My thoughts but others may disagree

Wayne-O,

Is that Wayno from near Safety Bay?? If so I have a spare intercooler, with fan, off a 2.8 motor that you can have for a play around. If someone doesn't take it out of my shed soon I'm gonna throw it out. I'm in Shoalwater. PM me.

I assume your thinking of a fan that will pull external air through the fins and not a fan that will blow air through the intercooler body - that's what the turbo does!!

I have fitted a fan to the top of my intercooler. It is a 9" thermo and sits well inside the bonnet air intake. The fan is bolted on top of the plastic engine shroud. Had to reverse the fan blades to make them push the air through the intercooler.

The fan cost $30 on e-Bay ( or just over a slab of Hann Premium light in real money)

Did it make a difference. I believe it did especially at low speed (1st 2nd gear) and low range stuff. I keep a log on fuel use and the figures appear to more constant since installing the fan. There are so many variants with fuel consumption I would not place much emphasis on the results at this point in time.

It worked for me

Like others have said, yes it should make a differnece. If you check the trader section, it just so happens I currently have 2 thermo fans for sale. The 10" unit would be ideal for your needs I would imagine.

Roachie,

Are we talking about the same thing here? This one that I've got is off a 2.8 Nissan turbo diesel and has the fan and wiring already fitted to the back of it. How come you need to fit a seperate fan to these others? Or is a 4.2 intercooler different?

Bilbo

well thanks everyone, i think i will invest in one on my next trip to the auto store, and no i live in karratha, but thanks for the offers, oh and yes the 4.2 has no fan, just top mount with scoop......thanks folks i will let you's know how it goes!!
