Post subject:  Replacing Parts on the Cooling System
Hi All,

I'm running an 1100 and looking at replacing the water pump as well as the radiator.

Is it worth getting a 'high flow' pump similar to this http://www.minisport.com.au/prod135.htm or just use the standard http://www.minisport.com.au/prod134.htm.

Also looking to replace the radiator. Is it worth upgrading to a unit with better flow such as http://www.minisport.com.au/prod63.htm or http://www.minisport.com.au/prod49.htm or better to stick with standard http://www.minisport.com.au/prod48.htm.

Will any of this make a difference or is the standard types OK? Any thoughts??

pulled existing radiator out tonight. It looks pretty good however it does show a tiny patch of corrosion in a small (less than the size of a 5c piece) spot on the guard side of the radiator as well as a little corrosion beneath the top tank where the filler sits (looking at it upside down.......if this makes sense).

Is this repairable or just get a new one?

The radiator (if yours is an original mini one and not one of the new ally ones) is made out of copper. As such it is generally completely repairable if the condition of the fins are still good. Small holes can be soldered easily.

Show it to a radiator reconditioner and they will let you know in a second.

I showed how to do it in 'Part 2' of my thermo fan how to located here: http://www.ausmini.com/forums/viewtopic.php?t=67382. That is the Matt Reid way of getting radiators out.

I've been told the a 71degree thermostat is too cold for the engine and too cold for the heater - any truth in the rumour?

Tested it on the stove and it was fully opened at around 74degree.

I reckon that's too cold unless you're in a hot climate. The standard thermostat is 82º, and in Melbourne I run either 88º or 92º with a hi-flow pump and standard Oz copper radiator. No hint of an overheating problem here, and the heater works well 8)

stick with that one for now if your doing lots of short runs and if you don't know the current cooling temps of the car. thats a summer thermostat tho and if she is running too cool in winter temps change it to a 84 degree one. if running hot ( with that thermostat 74 in winter) mabz check timing and tuning.
