Outer Limits 4x4 Board

G'Day mate,

I have a GQ Patrol and it kept starting to overheat when low range 4x4ing.

I found out it was the fan clutch by running the engine as per normal driving and waiting until the heat built up and then turned the engine off and turned the fan and it was fairly loose while hot.

To fix it ...

was told the best way to check fan is to get the truck up to running temp then pull over, open bonnet and watch the fan when you turn engine off. if the fan is ok it should stop almost instantly with the eng. it should also be harder to turn by hand.
also is it idling at different temps with air ...

yes same when cold as well.

is this when cold? ie many hours after the vehicle has been driven

Well from cold, and driving around 20-30 mintues, and the coolant temp reaching 2nd line on the dash.

Well I tried hand spinning the fan, but as others have said that it should not spin freely, nor should it be unmovable. And hence my doubt it is the clutch.

The fan moves with resistence, around 2-3 blades move with flicking the fan.

No not yet, what is the best way to check the Thermostat?

The temperature here in Dubai has started to rise, today's high is 38 degree, and in a couple of months, we will be seeing 45s on average, with night time temps of 35s. My coolant temperature never would go past 1/3 mark, the 2nd white line from the bottom, it used to stay at the 1st line in these ...

Is the axle housing definantly bent? When you say there is a leak from Knuckles, is it gear oil or grease? MAYBE the seal is not centered on the knuckle housing--check same amount of shims are under both bearing caps. When i had a bent axle housing on my GQ, it was almost impossible to remove the ...

To straighten the axle would be ideal, but there is no one here who I know would be able to do this from experience.

Well my GQ LWB's front axle housing is bent. Have replaced the seals twice, the leak was visible around the bottom of the knuckles within 5 weeks of new seals.

Anyhow the dealer has given me a quote for the replacement axle housing, which is AUD 2000.00. Now for that price I can do the following ...

I have a tb42E with less than 150,000 kms. Around a month ago when the weather was cooler, around 7-10 degrees C, I started using the heater at night. And I am not sure if this is related to it or not, but now on coldstart, and revving to around 2000-3000rpm there is a strange sound. Best I can ...

I am about to install a VHF/UHF radio, and want to use the best ground plane possible, that would mean just one location the centre of the roof. What I can't seem to figure out is getting access between the headliner and roof sheet metal safely without causing any damage. It's for a LWB GQ. The dome ...

Thanks for the feedback, I think I will drop this idea.

If I do add the tank and max air, as it is the cheapest option, would I see a good difference in times to inflate the tyres?


Also I heard that there was an article in one the magazines for modding a max air with a fire extinguisher, anybody know where I can get to read that article online?

I have TB42E LWB GQ, and have a portable Max air compressor. As we deflate to about 10-12 psi for sand driving, and lower for recovery situations, the max air takes a little time to fill the 33" tyres back to 35 psi.

So I am not sure whether to get a scrapped A/C compressor and install that, or ...

I have a 2" OME lift with 33" tyres, might not be worth it then. Dont want to go any higher as keeping the COG low is important in the dunes out here.

I have LWB GQ without a stabiliser disconnect, I was wondering whether if one can fit a stabilser disconnect to this GQ from a scrapped japanese safari?

Took the TB42E LWB GQ in to the dealer to sort out the front leak around the hub/swivel hubs. The rig has a 2" OME lift with 33" tyres. Not been jumped, just loads of dune driving. I had taken the GQ to another mechanic before in Jan 07, to repack the hubs for leak on the RHS only, and asked that ...

*bump*

for the number 2 one, that is a Mainshaft bearing. mine does the same and thats what i have been told the prob is by gearbox specialist.

You say that your's does the same, I take it you have not bothered getting it fixed, if not any reason? And how big of a job is it to replace the main shaft ...

Need some help with diagnosing 2 separate clutch sounds. I have a GQ 4.2 EFI with aboud 140,000 KM on the clock. It has a custom extractor and flow through exhaust.

1) When the engine is at normal operating temperature, i.e. first marker on the coolant gauge, the clutch pedal returning from ...

multi meter with a spike sensor on the +ve and earth the -ve on the car. Get the G/W wire spike the insulator with the multi meter sensor and get a mate to engage and dis-engage reverse. You will see the reading jump on and off. Once finished just tape up the small pin prick hole to stop water etc ...

Also, you can get to the wire where it runs under the bonnet in the big bunch of connectors next to the battery.

This may be a dumb question, but how does one check whether the wire is the correct one if it is insulated. E.G. I engage the reverse gear and want to find the live wire from the ...

I am trying to wire up a rear auxiliary light. I want to be able to have it on continuos from battery, will wire off the cab fusebox, as I have a spare fuse socket.

Also the light should switch on when reverse gear. I have found the diagrams for this ...and to have the reverse engage one has to ...

Hi Exhaustfix,
thanks for all the help you have provided us thus far. I live in Dubai, UAE and I have a GQ LWB with a TB42E engine. We are left hand drive here. Most of the extractors and exhaust systems we get are US makes, as seen here http://www.goldencaruae.com/Products-Exhaust%20System.htm I ...

GQ4 thanks for the reply, have a look at this website mostly patrols from Dubai. http://www.toprpm.com/eng/4x4Features/mainFeatures.htm

Does anyone know of a software and hardware kit that allows to reprogramme the Patrol TB48E ECU. Initially just to reset the software, copy from other models etc etc.

Also what are the main ECU upgrade companies out there, Motec, Unichip etc. This is for a mechanic buddy of mine who does ...

I just installed 305/70/R16 (33"X12.5"x16") with 16x8.5 (stock offset) rims on a LWB GQ. The GQ had a 2" OME lift already. I was flexing the new tyres, and it seems to rub a little in the rear at full compression.

Also my front rear coils are clanging due to worn spacers, which are stock. So maybe ...

I have downloaded both the files from phatg20 and installed successfully for Y60 (GQ) but need to know or find any files for Y61 TB48E engine, the files only the TD30 and TD28 engines for the Y61?
