Mods to cooling system pending shipping down under

[DDubya]

Markiebabes and I visited Raterace last week and started to discuss doing some mods to my cooling system in preparation for shipping the car to Australia, given the higher ambient temperatures.

 

Car is an unmodded Superlight 1.6 (K series). I have been looking at the various options for rads but am totally confused. Will also fit a lower temp stat and an additional cooling fan.

 

Over to the power of BC to produce lots of useful advice and help please.

Larger capacity rad

Larger diameter fan

Fan manual overide switch

lower temp fan switch

 

These would seem sensible to me to help get the temp down quickly once the temp starts to rise in traffic etc. Not sure about a lower temp thermostat though as you don't want the engine to run too cool.

 

I'm no expert so could be talking complete Horlicks here 😳

I would agree with Ric. It's not the temperature you want to change it is the cooling capacity/temperature management.

Your optimum/prefered temperature should be the same irrespective of the country in which you are located.

Last consideration would be a remote thermostat (i.e. one between block and rad rather than one at the entry of the cool return to the block)

hmmm. if standard car I'm not sure you need anything extra over current UK spec. On the USA tour we ran in 100F+ temps for hours at a time and cars didn't seem to particulary struggle with the heat (unlike the occupants). Some cars did have coolant issues during the tour, but these didn't seem to have any particular relation to the hot ambient temperatures..... one heat related incident was an Emerald ECU packing up where it had been mounted straight to the chassis. When everything cooled back down it was fine...

Caterhams are exported to OZ and sold through their distributor in Melbourne; you could ask CC what specification they export

As Neil says on a standard car I'd be suprised if you'd need to do anything, my 260bhp Duratec was fine in the USA 100F temperatures, a lower powered car will cope even more easily I suspect.

 

The only mod I have is a Radtec radiator rather than a standard Caterham one.

Yup - just keep moving forwards to make sure there is a bit of a draft!

Thanks

 

So the overall opinion is that it may help having a lower temp stat and a larger rad. I have had a look at the Radtec unit at £200.00.

I thought we agreed not to have a lower temp stat?

OK, but Mark and the guys at Rat Race reckon that my normal hot weather, in traffic temeratures of mid 90's to 100 is too high, Mark has fitted an stat that is around 85-87 degrees, plus the fan and manual switch.
