Thread: Series 2a cooling

My understanding is its predominately the holden conversions, that run hot..?

There's a thread in the Series Three section on pusher fans.

I've never had cooling issues with any of my series trucks - my diesel Gromit barely ever gets hot; even in these Sydney temps - it sits in the middle of the N on even the warmest of days, even when toiling up the Kurrajong slopes.

I think a nice clean, well maintained radiator should be more than adequate with the existing belt driven fan.

Maybe you'll only need the Kenlowe if you're going to cross the Sahara?

Pick up the optional 8 blade fan, as fitted to the military landies. Should move plenty of air.

Grommit can I ask though have you hauled heavy loads in the heat?

this little car when built will likely be doing wood runs from the state forest and jobs such as this..the car will not be used much but when it is it will be doing the heavy load hauling..

so i guess I also want the thoughts from people that use their cars not just drive around in them on hots days...

I'm taking into consideration that we are currently hitting the 40's in Sydney and are often in the high 30's in the summer

The standard cooling system is fine for a 2.25.

I previously had a 2.25P and now have a 2.25D - both tweaked slightly. Both of these engines ran the same 3-core aftermarket rad (a 5-core replacement of the OEM one was to $$$ back when I was a poor student). I also run the original military 8-blade fan. I have never had a shroud fitted. I have never had an issue with cooling.

I have hauled 1.5T of wood from down near Landy Andy's place to Perth - about 150 km - though mainly in winter.
I also drove Brisbane-Perth in summer while fairly heavily loaded.

Not to mention plenty of difficult 4x4ing - not much airflow when moving slowly.

Thanks Ben

if that's the case I wont bother

I guess i can always fit one at a later date if we find its not coping

Thinking back, I did lose a small amount of water from the rad once when playing silly buggers on a salt lake in 2WD, but that is the only time, and obviously only because the engine was working quite hard and the car was essentially stationary. I haven't had any problems in soft beach sand in summer.

I have operated both petrol and diesel 2.25s in the Simpson Desert in summer without overheating, and have never had an overheating problem on any 2.25 unless there was a defect. My current 2.25 I had no problems with it hauling a trailer with a tonne and a half of rock this January (mid thirties!). And I have removed the military fan to try and get some small improvement in economy! Note that I have always retained the shroud, and have always fitted cylinder head temperature gauges to my 2as.
