2009 Defender 110 Puma 2.4 SW Alpine White

Engine Temperature / Winter

This is the first winter I have had my 2.4 D110, and I have a question regarding engine temperature. Normally my engine temperature once warmed up is approximately 95 degree C. This is read out on a Madman EMS2 installed, verified with a GAP Tool diagnostic reading also.

What I have noticed in the really cold days of this winter (-2 to -6 degrees) that my engine does not get up to temperature fully during my short commute to work. Approximately 10 miles / 20 minutes. Usually top out at 82 degrees C. The heater blows out hot air as usual. The problem is when I am idling at lights the temp drops a few degrees or more drastically when I needed to wait for a train to arrive one evening the engine temperature continues to drop all the way down into the mid 40 degree C range. Not sure if this is normal or if there is an issue with the thermostat (which is new) or the fan?

FYI - Allisport upgraded radiator and intercooler installed.

Thanks in advance for the help / advice.

My Defender is the same and I think that the standard cooling system will cope with towing a heavy trailer across the Sahara

Just because you're offended doesn't mean you're right.

Mine runs at pretty much 90C in all weathers. Drops to about 84/86 when stationary in colder weather.

I’d be checking your thermostat, also your upgraded radiator may have more of an impact.

Out of interest is your egr fully operational? Or blanked/mapped out? 2011 Defender DCPU 2.2 - https://www.defender2.net/forum/topic30623.html

There was somebody on here not so long ago with one of the Allisport rads that reported something similar. I think it has a lot more capacity than the regular one. Darren

EGR is fully operational.

How would I go about checking the thermostat?
