Still with problems in high temps :cry:
Hi there!

Despite the change of the intercooler for a larger one and the new BAS remap I suffered again the problem of high temperatures and the safety management strategy. Crying or Very sad Crying or Very sad Crying or Very sad

The problem happened during this weekend with temps near 30癈 with no more than 250 kg load (just 2 persons, 2 childs and the empty roof rack).

We were in a uphill of approximately 12 km with an slope of 3 mt every 100 mt at speed between 110-120 kph.
At the end of the slope the temp gauge goes up to the red zone very fast and the management strategy started. After few seconds we stop the car and the temperature come down very fast too (taking 5-10 second to goes up and goes down).

Im concern now about what happens during the vacation period with the car fully loaded at high altitudes and towing our folding camper (1.5 ton). Confused Confused

Any thougths about what can I check?

Cheers Eduardo

I would personally start from scratch and put everything back to standard and repeat the drive (test).

You need to reduce the number of variables and start a known base line.

Ian,

Thanks for your prompt answer.

This is an old history.

The problem started time ago when I dont have installed the remap and the intercooler and the situation was the same:
High temps at 110-120 km/hr under load (uphill or loaded) produce the cut off,

So a 3% incline, ie gentle slope.

Do these cooling systems have a thermostat?

What have you got in the way of diagnostic equipment - that can do live data?

Really for problems like this in the past I've thermocoupled vehicles up to trace what's the route cause.... I'd be very keen to look at actual water temps before and after radiator, themostat operation, oil temp, oil cooler in and out, air intake etc... and a couple of other things. I'd also look at coolant temp sensor.

Changing the intercooler wouldn't change anything in my opinion as not an intake air temp problem. IRB

Porny,

Thanks again.

I have the typical Bluetooth ODBII reader with an android app that can store live data from the ECU (Torque pro).
It is enough or I need something better to do the job?

Thermocoupled the car can be more difficult but not impossible from here if I can get the rigth equipment and the cost is not prohivitive

I can confirm that something isn't right. I have been in same situations, higher temps/ altitude and had no problems and have a winch/ lights blocking 50-60% of the front grill too.

-Thermostat could be a bad one- check that the radiator is getting hot when temp goes 'high'- be careful- might be cold... or might be very hot (and watch out for spinning fan Wink ).

-Is there air in the coolant system? Had cooling problem on partners car- all it was in the end that the little hole in the thermostat was at the bottom instead of top which resulted in a pocket of air- would overheat on long hills as flow was restricted.

-Does turning the interior heater up to full temp and putting the fan on full help?

-When hot, can you hear the viscous fan whiring- when mine has kicked in I can hear it over the engine/ stereo noise (should get louder as radiator gets hotter).

- Blocked radiator- some gunk might have got in there preventing flow?

Other possible question (I am unsure of these parts of the system):

How many coolant sensors does the engine have? If it is faulty the element could be breaking down at a certain temperature resulting in the sudden raise and fall in temp (and cut-out). I have read before that the dash temp gauge is very unreliable- will sit in the middle for about 20 degrees C variation but then goes to full with another 5 degrees C.......... Don't know how true this is though Confused

Just been looking and the thermostat on these are VERY easy to change, part number PEM100990 and is used on the Td5 too.

Don't know how legit it is- just going off what I have found on Microcat and haven't checked on my truck.

Do you keep your foot flat in 6th gear? Or do you change down to 5th on these climbs?

I've found that keeping the car in 6th on a long climb will increase the coolant temps to more than 96degC very quickly. Changing down to 5th then drops these coolant temps very rapidly.

Aren't you pushing it to much in a "overdrive"/high gear?

Thanks to all for the answers I have at least something to start.

In fact I use to drive in 6th all the way and probably that could be one of the reasons. On the other hand I made the same route several times before without any trouble.

The problem appears 3 years ago in the Patagonia and from there appears randomly 4-5 times in a year (but always when is hot, at high speeds and with the car forced)

What is this "radiator protection net" you mention in another thread?? Pov.spec,ftw. 2006, 110,TD5.

Jimbo,

I dont think so.
This net is very open (thin wires with a separation of 3/4" and probably do not restrict the airflow more than 5%.

6th should only be used to cruise on level ground (and downhill). As soon as you hit an incline and the revs drop below 2000, you should gear down to 5th.

Do you also monitor your EGT? That's one of the best ways to know when to hear down IMHO - whenever I tackle a hill, I keep one eye on the EGT and as soon as it shoots up I gear down and the EGT goes down as well. --

So basically the OP labours the engine in 6th, up an incline for circa 12 kilometers, and then wonders why it's hot!

I do this road several times in the past in almost the same conditions without this problem, for this reason I'm asking for help.
