Outer Limits 4x4 Board

Well summer has arrived and engine temps are going up, I need to get the hot air out from under the bonnet and have just bought some vents from whitworths marine they are a 3 louvre engine set and was just after some advice on where is the best place to fit them on top or side of the bonnet. any advice would be appreciated
TIA
Dixie

ps it's a 2 door with a 308
and i have pictures just don't know how to post them

sides of the scuttle panel (spelling) is a good spot

Have a look at mine.

I have the whitworths 3 louvre vents on each side of the bonnet to let hot air out and a nissan patrol bonnet scoop to let cool air in...

Makes a big difference on long trips...

I would say that would depend on when it is that you are having problems.

Hot air rises, so if the problem is when you are going rear slow the best place would be on top of the bonnet. (have seen a reversed wrx scoop work very well in this instance).

If it is more at cruising speed then the air flowing through the engine bay is more likely to be forced out through scuttle panel vents.

Have a search in this section also for information about cooling and the negative effect that vents have on forcing cool air through the radiator.

They look good I'll think put mine in the same position, did you paint yours black or did they come that colour as mine are polished stainless (the bling effect)
Thanks again
Dixie

Mine are a bit further back

I just spray painted them with engine enamel and are attached with rivets...they get pretty hot!

Hey maggott, are those vents on your scuttle panel the same as the vents on the rear vinyl covered panel? How did you attach them?

Andrew, is that a P6B next to your Rangie? Is it yours?

Hi,

On this topic you could have a look at the discoveryauto site from WA. They do louvred bonnets etc.

I'm running a 350 Chev with a standard RR 3.5 radiator and have recently put twin thermos behind the rad, one fan running all the time and one on temp. Cost 195 for the themos with surround, 50 for the temp switch and 5 for the relays. Works incredibly well. Never gets over half on the temp gauge now. When you see the twin thermo shroud you'll see why it works so well.
Also water pump will last longer because it doesn't have an out of balance fan hanging off it. Only 100 bucks for a Chev anyway.

just another option, DL.

Not mine...but it was in great nic. The photo was taken at a "All British car display" which is held in Brisbane once a year. There were quite a few P6B's there.

My old man use to have a P6B for many years. It was "tan" in colour (not sure of the official colour) I was always fascinated by the front suspension set up. Very comfortable car to drive.

So when will we see it?

Hi 6.5,

Have images, but can't figure out how to post. Will send to your email. Feel free to post. The thermos are an EL Ford copy and come with the shroud which just needs about 10 mins trimming to fit RR radiator. The fans cover a huge area of the radiator. One runs all the time ignition is on, the other is governed by an adjustable temp switch, with the sender in the top rad hose.

Made up aluminium brackets from shroud to the two RR radiator mounting bolts to take the weight, as I had probs in the past with cracked tanked seams.

cheers, DL

I had a set of these fans but was no way they would fit (mine runs an MQ Patrol radiator) as they were to wide. Now i run two 12" Davies Craig, but they sit about 15mm off the radiator so i will need to make some sort of shroud and the vents that i have either side of the scuttle are now blocked by duel snorkels so will have to do some sort off bonnet scoop arrangement.
It runs cool until i shut the bonnet

Sorry I dont have a real photos of the car any more but I did manage to find this. This was A rangie I built a while ago. As you can see i put a huge bonet vent on. The side werem ade of alluminum and bought one of those aluminum door vents from bunnings. It was a reasnably cheep thing to build but the car never ran hot as all the hot air was directed up.

It looks like the illegitimate child of a Rangi and a Hummer!

that was the idia!!
