I dont want my mog to over heat, any tips?

Off the top of my head I'd say fit a temperature gauge is you don't already have one so you can monitor temp.
I assume if everything (rad, pump, fan belt, thermostat, timing, carb setting etc) is OK then it should be alright.
At the absolute worse if you find temp is just too high then I suppose a radiator specialist over there should be able to rebuild with an uprated core.

BTW Rain almost every day for weeks - missing it yet ?

I have to say it has been hot as hell here. No rain for atleast 2 weeks. I have been to a Watermelon Festival, and on August 3rd, I am going to a Possum Festival.

In addition to the above, make sure you continue to use anti freeze, as this increases the boiling point of water.
Glad to see you are getting the use out of it across there - my mate's minor (same as yours) is due to land shortly prior to transfer to Grand Junction Colorado.

luck you ben with the hot weather how are you

What about fitting an oil cooler? that would take some of the work of the cooling system. I believe it's fairly easy to find the necessary parts. I know of one 1275 traveller with the bits.

4 blades on the fan, a standard thermostat not a high rated one and that's about all you'll need.
The Minor radiator is good enough, as long as the water gets to it.

In my limited experience, an oil cooler is more likely to give you trouble than save you from it. If you've tuned it up and fitted a turbo, that's a different matter!

It can be warm here too, in NZ, but not at the moment. Everything in the cooling dept on mine is in good shape and is suitable to keep things as they should be. One time that is a problem, especially in warmer weather, is sitting in stationary traffic. The std Minor fan does not work too well at idle and the car can get quite hot quickly. A temp gauge is essential. Since fitting a thermostat controlled electric fan this slow traffic overheating problem has gone away. Interestingly, even in the height of summer, this is the only time the fan will turn on.

Not seen rain for months here.....

Just got back from a 1700 mile tour on my bike round Yosemite & lake tahoe with some forum members... about a dozen 30 year old bikes. The only one anything broke on was the brand new Honda Interceptor one of the guys hired..

There's hope for you lot flooded out in Blighty yet.... I heard on the grapevine that help was on the way

I have moved this to General Discussion as its more relevant.

presumably in stationary traffic one can simply turn off the engine?

Thank god for The Hoff, what did we ever do without him

I think I warned you before you went there to fit 4 blade fan. You can (instead) fit the multi blade Spridget/Marina fan - that will shift a load more air. Also - 74 degree stat - or fit a thermostat blanking sleeve instead of a stat - but DO NOT run without a stat or sleeve in there!

presumably in stationary traffic one can simply turn off the engine?

That often doesnt help Juliet as the engine temperature continues to rise for a little time and you then may find you cant restart due to fuel evaporation this is what can happen over here in a traffic jam when the pump starts to tick madly if you cant keep it going you will find it can take 15mins before things have cooled enough to re-start.

Pouring cold water over the fuel pipe where it rises to the pump can help. Unlikely, but true

electric fan is going to be a very good idea, it is most likely to overheat while stationary, and as other people have said, the mechanical fan does not provide enough air speed through the radiator to cool it in hot weather.

It easily DOES if it's the Spridget/Marina multi-blade fan!

yes but an electric fan wont sap power in the way a mechanical one does, having an electric fan is a much better solution to the problem, in my opinion. A large mechanical fan will help keep it cool at low revs, bit will absorb power from the engine at higher speeds, when the fan is not needed. How many modern cars have mechanical fans bolted onto the water pump?

But this is not a modern car - and may not be going fast enough for good 'ram air' cooling. Nor is the rad a modern high efficiency alumin(i)um unit!

I find with mine, a thermostat controlled electric fan, that almost any foward movement is sufficient to move air over the radiator and drop the temp enough to turn the fan off and keep the car cooled. This means crawling in 2nd gear in traffic upwards. It is only when stationary with the engine idling that the fan will turn on, and even then not continuosly. In this circumstance the 4 bladed fan could not move enough air and the car would overheat. (It did more than once)There is also the benefit of a quieter engine bay and no fan running to absorb power at higher speeds when it isn't needed. This is from experience of being stuck for over 20 minutes in stationary, or nearly so, traffic with outside temps over 30°C.
It may not be the original set up but it works and I find it essential for the car to cope with todays "free flowing" traffic.
