Don't want to overload you with info too soon, but an upgraded intercooler is also a good idea. Maybe not quite as important on the 90 as the engine isn't working as hard, but still a good long term preventative maintenance measure i.e. cooler cylinders and head and slight fuel economy improvement.
Yeah I can imagine it would. Just put a Turner performance head in my 300tdi and a bigger intercooler. I need to get the sucker tuned properly now..Quote:

It.never.ends.
Yes they keep our spare money and time taken care of!Quote:

Even though you've still got the same cooling capacity with the radiator, its keeping the head at a nicer temp for the 99.9% of the time when you're not exceeding the radiator's cooling capacity.
The oil also stays a bit cooler and keeps the oil pressure up a tad.
Interesting, first I've heard of the thermostat change Beery. Any more info?Quote:

Yeah that thermo would make a difference for mean operating temps for sure. Will be moving down to SA soon so will be agreeable with that heat.
I will do the Alli-cooler upgrade once the engine has wore in down the track. She will be a daily carting arb bull bar and nothing else. Keep my 1994 for the nasty work business. Going to try and preserve the 90 best I can and stretch it's legs off road every now and again.
New Defenders are exciting!
An added bonus is the much better drivability with a BAS autobiography tune. And back to standard tune for a Warrenty Service, takes 5 minutes,
Am a bit hesitant to do the I/C upgrade in case something catastrophic happens to the engine, even if it is innocent.
Its mainly an effort to protect the head and head gasket for puma's working in hot climates.Quote:

The engine bay is noticeably cooler when I lift the bonnet now, reducing heat stress on all components living in there.
The original thermostat isn't fully open til 96 degrees where the replacement one is full open at about 88 degrees.
It means when the going gets heavy, the cooling system is being fully utilised earlier, giving it more chance to pump the heat out rather than waiting til things are stinking hot.
This also brings the fan in earlier, boosting airflow (depends on road speed and revs obviously) over the intercooler, radiator and engine bay.
The standard radiator seems to have enough capacity for most situations...those where it doesn't just need a bit of driver common sense. Increasing the intercooler performance and closing the EGR will reduce demand on the cooling system a bit.
Again, all long term preventative measures
G'Day Beery,
I'm also interested in this thermostat change for my 08' 110. Do you have a part number?
Cheers,
Lachlan.
Gents,
You need to be careful with putting in colder thermostats on diesels, as they need to be run hot. Compared to a petrol engine that is....
Dropping down to a 82? thermostat is fine in warmer areas. Not recommended for cold hilly areas, as the engine can loose to much heat in a long down hill....
I put a colder one (82?C) in my 200tdi, and it was fine, except for going down Greenmount on cold mornings. Temp would drop a tad more than I liked....
Before the remap, but with the Alisport fitted, my engine used to sit at 92 - 93?C for most driving on the flats. With the BAS 170 remap, it sits at 88 - 89?C. But it will go up to 92/93?C if you start doing some work in a warm/hot environment.
My remap has the EGR turned off. :) So perhaps it is that making a difference.
I would certainly like to know the part number of the 82?C thermostat. :D
Coventries sells the 82?C thermostat for the 200Tdi, for those who are interested.
Cheers,
Phill. :)
I was amazed at the temperature variation of my 2.2 with 170 BAS remap and Allisport intercooler as reported by the ultragauge. Working up hill towing the new camper trailer it wasn't uncommon for the temp to go up to 96 to 99C, while coasting downhill can see it drop to 82C. On the flat it sits nicely around 89 or 90C.
On the run into Toowoomba going up the mountains the temp peaked at 104C which was a bit of a worry but there isn't a damn thing you can do on that road other than keep grinding along.
