Eastry - what do u mean by back? Sorry if thats a stupid question but its me that is asking

IOM - sooty carb?

I have been using the Chief all this week on B roads for up to 90 mins continuously in the mid day sun and not a problem so its 100% a motorway problem

Bulldog67 · « **Reply #126 on:** June 11, 2014, 08:19:49 PM »

One extra that may have an influence is that once its been running for 30 mins or so and I floor it from crawling or standstill it has cut out a couple of times

Further thoughts would be to make sure you include a sort of overpressure relief flaps in the surround between the rad and fan shroud so all the air pushed through from the front, as you belt down the motorway, has somewhere to go but is prevented from recirculating round to the front of the rad again.

rad caps with a temp guage...bottom of page

Now that is cool

By the way, got the flowkooler parts direct and they only charged $12.45 shipping

Bulldog67 · « **Reply #130 on:** September 04, 2014, 07:03:30 PM »

New thermostat, water pump, sender unit ..... and ......... fuck all difference

More cash wasted

So winch off 2mrw and buying some hardboard to make a tray to channel the air.

Was gonna tow the Chief to CF on a trailer using the XC90 (2.9 petrol) but dunno if that would be legit

Anyone know where I can buy a fancy aluminium rad in the UK before next Weds?

Bloody hell mate. Not good and not much time. How heavy is the chief

What's the xc90 tow weight limit?

With. Trailer....... Your going to be perilously close to 3.5 tonnes.......

Because I am.......to give you an idea of weight........

Daft question but if you drive 55 does that not help....

Bulldog67 · « **Reply #135 on:** September 04, 2014, 07:49:18 PM »

2250 according to the owner manual

I have tried Jez, don't matter what speed - even tried tailgating lorries to use their slipstream but no good

wildwood · « **Reply #136 on:** September 04, 2014, 07:58:01 PM »

So it's down to the tricks of carpentry to funnel air to the rad.

I know its too late for CF but on Pirate they keep on about matching the cubic inches of the engine
to the square inches of rad....... And that's core size not overall size....... The bigger the better

( she gagged expectantly)

JamesH · « **Reply #137 on:** September 04, 2014, 07:58:03 PM »

I'd guess at 2500kg for the chief and 700kg for a trailer so 3200kg, acceptable for a 3500kg rated tow car if you are sensible but doesn't sound like a good idea for the Volvo.

Odd that slower speeds don't help, have you tried blasting hot air out the heater to see if it drops temps at all, even a bit?

Very puzzling! Could be a weird air flow thing.

slipstream is still air / air being pulled so may not help
Air ducting is you best bet imho

Might as well go triple core if you're going to the bother of custom.

When the ZJ was over heating, having the hot air on And the bonnet popped did make a huge difference.

Volvo should tow 3.5t ok just take it easy.

Volvo XC90 max 2250Kg towing cap

Dave69 · « **Reply #142 on:** September 04, 2014, 10:03:38 PM »

old skool was to have heater on full heat and fan on high and windows open as a help to taking heat out of the system.

as said previous, no point throwing money at something where you don't know the root cause.

thermostat is only for engine start up (kettle and hot water will confirm operation)

water pump, water is still pumping round.

radiator is it sufficient to cool engine? O.E then it should be.

fan shroud if no shroud and a single fan then this is where you really need to look. seal the engine side of the rad to the shroud so all the air will be sucked through by the fan from across the rad. (No COST use cardboard to start with)

if this improves then put an under tray on the jeep and see if that has an effect. (Use cardboard but be mind full not to put the card by hot exhaust)

Just bring the XC90 its 4wd isnt it?

Bulldog67 · « **Reply #144 on:** September 04, 2014, 10:43:55 PM »

Cheers gents - freeby tricks first and then rad but wont be able to do that before CF

Its a shit

Reckon the xc will be used at this rate anyway but not round the site lol - will be making it a shorter weekend tho if I cant drive around

Bulldog67 · « **Reply #145 on:** September 04, 2014, 10:55:53 PM »

Sods law that usually there are some off road ZJs for under £1k but none about so I cant even go that route for the weekend

All I can find is this but its way up north anyway: http://www.ebay.co.uk/itm/Isuzu-Trooper-3-2-V6-taxed-and-tested-4x4-off-road-/191310550881?pt=Automobiles_UK&hash=item2c8aff5761

Lost the thread of this, no pun intended, did you ever fit the extra trans cooler??

I was going to try one of these, self regulating....

Bulldog67 · « **Reply #147 on:** September 04, 2014, 11:29:54 PM »

have got a transmission cooler but not fitted yet - the transmission currently uses the rad and im not convinced it will help the air flow so its a last resort job

5536paulj · « **Reply #148 on:** September 04, 2014, 11:40:07 PM »

OK, It'll be my first resort, I'm convinced mine is related to big tyres and not low enough gearing generating loads of heat in the transmission at speed, I'll arrive at Cheapfest spewing ATF as per normal after a long drive....

Personally I think airflow becomes a non-issue when driving a brick, but what do I know, when i eventually get around to fitting the cooler i'll let you know the results

Bulldog67 · « **Reply #149 on:** September 05, 2014, 07:13:47 AM »

It's also a skills issue
