Thread: TD5 Temps, when to worry?

Towing 2.5T???? I would have expected maybe a bit more than that. Don't forget though that as the cooling system is pressurized, boiling point is raised and is also controlled by coolant additive too.
Anytime you put it under extra load it's going to rise.
Sounds like a pretty normal scenario.
Get an EGT gauge, this will tell you more about how much load your putting on the engine.

I would say your temps are OK,but watch them close.Use lower gears when under load.
The sister we just purchased is turning very low temp readings,less than 1/2 on the temp gauge,80 to 90 deg on Nannocom.
BlackBetty registers 88 to 101 in the same hills,but is chipped.
5teve was getting the same temp readings as my D2 before ECU upgrade on his Deefer.Nanocom gets the real temp,from steering this Deefer of ours I believe the Deefer has a real temp temp display,the D2 stays in the middle despite the real temp.
May be better cruising a tad harder in 4th than using 5th???

Thanks,
Thought that maybe the case, but as I have not seen the temp go above 95 before thought I would pick some brains.
Thinking about getting a 3" exhaust to help the exhaust gases flow better and control EGT so will get the shop to fit a port for a lambda sensor and fit a gauge.
What is the best location for it?
Amazed me that it was all uphill for 500kms from Cue to Newman. Truck drivers and other travellers confirmed this and from a park bay nth of meeka elevation rose from 430m to over 600m. Wind was a real drama but still managed to cruise at around 80kmph most of the way.
Around 2.5 tonne and the Fender actually towed it great but it is also a really good trailer, enclosed canvas about 1.8m from deck, deck 5m long x 2.5m wide. Trailer 900kg, Torana 1200kg plus DRZ400, TTR110 and some other stuff.

On the plus side I should be able to roll all the way from Newman to Perth.

Hey Andy, yeah Shrek usually runs 80s to maybe 90 not towing and up to 93 towing the van on hot days, just first time I had seen it hit 100. But as said did not seem hot at all to touch or smell.
In Newman tonight, so here to a new life.

I wouldn't bother with 3" exhaust. Your better off getting a highflow muffler or a straight pipe replacement for the centre.
Going too large in the pipe can cause the turbo to overspool and the nest way to do this is use a too large exhaust.
A exhaust with a nominal I.D of 10% larger than the turbo pipe is ideal and this is the size of the turbo pipe.

As for the EGT, you need to drill and tap a hole in the exhaust manifold right at the turbo mount as it's the hottest part. Post turbo won't give you a true reading.

I am not being a cynic nor do I write this with any malice whatsover.......It's just that I flew fixed wing and helicopters for years before settling down to a 'real job'

One of the benefits of aviation is that most aircraft have a gauge or a 'tell-tale' to tell you the temp or measure metal fragments of just about every moving part or liquid on the aircraft.....whether you want to know or not!

Aviation is quite safe....it's just very unforgiving if you suffer a component failure at height so it pays to know what is going to fail and when.

With that mind set, a fellow TD5 owner and former aircraft engineer I knew when we worked in WA decided to fit temp gauges to both front and rear diffs, his gearbox, engine oil and fuel tank as well as an EGT so he could continually monitor the condition of his running gear.

All of a sudden, this amiable guy became obsessed with every single temp change or thermal spike (As he called them) and would even pull over regularly and peer under the bonnet or climb under the car to check nothing was amiss. It was worse on a long boring trip when he would regularly call me on radio and give a running commentary on - a 3 degree change in the rear diff!

Dare I suggest that may be we are starting a trend of doing the same with the ever availability of instruments that supply a lot of real-time 'nice-to-have' data, but not necessarily useful information. ????

I can see this same 'obsession' emerging with many other 4WD owners who in the past, would drive in 40+C ambient temps, aircon at 17C and towing over loaded trailers blissfully unaware that they were doing no damage whatsoever to their vehicles apart from minimal (Less than 10%)thermal overload that would stabilise once the temp or load decreased.

Keep an open mind - I mean no offence, just putting a point out there!

Could not agree more.I have met,and there is quite a few on this forum who start carrying on about oil testing and the results and how this is wrong blah blah.The worst thing about it is people will spend money on things like overtemp warning alarms instead of proper maintenance to stop the thing overheating in the first place.Craig,as long as it stays under 110degree's I wouldn't worry,you are towing a heavy load.

Do you know how many times I have contemplated doing this very thing?

Don't worry Craig I have seen spikes to 104* in mine when towing at 7t GCVM.
