im thinking the troll is feeling the affects of the 220 roolites mounted on bullbar in front of grill, went for a hour n half drive in 30+ heat country driving today and clutch fan was working 98% of the time with aircon on... i remember last summer it didnt work that hard coming on for a few minutes n so on... factory temp gauge so its always sitting on half.. troll totally stock apart from electric usual goodies

yer thanks not going to check much since i did the coolant few months ago thermostat is in a ***** of a spot and clearing air out of the system is a job of itself , it was very hot conditions tho and the temp gauge didnt budge from usual spot, did the research and thats how i got my conclusion leave it drive it until i here some alarm bells what ive learned is get a after market temp gauge

Hey I have a 99 2.8 and have only had it for a short while and have had the clutch fan redone at the local radiator shop and i also noticed its on a lot even when the enging is only just starting its on. Have you noticed any other things to make it do it?

yep, every time you start 4b clutch fan is on,then drive it down the road it will disengage by the time your in third gear,,, but mine been staying on 90% when outside temp is 30+ deg outside temp... i wasnt sure how other 2.8gu's clutch fans are operating when its 30+ deg outside...

i never hear my fan operating so you guys are doing well.
If you are looking at fitting a aftermarket gauge i would suggest you purchase a ECU talk as this is a lot better than another gauge which you need to keep an eye on. You can set a alarm in the ECU Talk to beep when your engine reaches a set temp.
Just a bit of advise in regards to your clutch fan. if you suspect for a minute that your engine is running hot get your cooling system looked at (get radiator cleaned) as i have just had to replace my head head this year due to a blocked radiator. If you are waiting for the facotry gauge to move you are asking for troubles as nw i have the ecu talk installed i can see the factory gauge seems to stay at it normal level up to 95 (highest i have had the temp since the repairs).
There are plenty of Patrols driving around with winches and spot lights fitted that dont suffer cooling troubles so i dont know if the lights are causing you and hassles.

how do i check for radiator flow without pulling anything apart??? eg: top hose cold, bottom hose hot = radiator blocked???

The top hose should be slightly hotter than the bottom hose. If the bottom hose is alot cooler than the top hose you have a restriction.

if in any doubt and for the cost (around $200) just take it in to a aradiator place and have it cleaned.
You never said how many Km's you have done or how long you have owned the vehicle

purchased the ecutalk cpl weeks ago,,, on way home yesterday coming down the f3 i was getting 99c going up the big dipper (mooney mooney bridge)...checked clutch fan this morning 2.8gu there's only little bit of resistance, 4b hasnt been started since yesterday....

So the question is 99c is getting bit to hot, how much resistance should there be on clutch fan when its stone cold???

Ill go with camo on this one
Get the rad rodded (cost depends IF you remove and refit or they do it)

If the car is constantly running hot , your putting to much pressure on other components

A blocked rad is a common issue towards heating probs

when i had my radiator done the guy said that it is common for the top tank to be blistered inside too, if it had been overheated.. mine was 70% blocked and the top tank was rooted. cost about $220 off memory. new head cost me about $1600, 99 degrees would bother me.

if its any help we went to Melbourne on new years eve and i was waiting to see how much hotter the old girl would run with the outside temp sitting on 40.
To my surprise going along the hwy with the cruise on sitting on 100 the CU talk never went any higher than 90 degress (hilly). Most of the way though it sat on 86-88 which is what it normally does. i really thought that the hotter weather would have made it run a little hotter but it was not the case.
The hotest i have ever had mine to is 94 when i was pushing it up a hill near home. I'm not sure how long yours was running at 99 for but it sounds a little warm to me.

Hey camp road I know the F3 well and yes Smokey gets hot on the mooney bridge too mainly when heading south on a hot 35c+ day nearing the top of the climb. Hot as in I haven't got the ECU talk yet (coming) but can rise to 3/4 on the crap temp guage.

Also the is another chit hill heafing south before mooney bridge, its a slow gradual hill just south of the westfeilds a tuggerah - it has a slight bend in it halfway up....this one kills Smokey near the top on hot days..
I know Smokey gets hot cause I can hear the aux fan come on when the a/c is off when in deep sand etc as this is set to come on at 98c by the ECU.

Let us know how you go.
