The warm heat of mallorca is getting the best of my mini I'm afraid, the old owner neglected the coolant in the system and it's a little gunked up, I already gave it some acid treatment and changed to 10% antifreeze and cooling is much better, but I'm still waiting on my thermostat gasket so I can take it in to the radiator shop for a proper de-gunking.
Anyway, long story short I'm trying to optimize my cooling for the warm summer ahead of us, I'm currently considering the following:
- High capacity water pump
- New Radiator
- Electric fan
- 72ªc thermostat
What radiator is best for road aplication, I've read that 2 core are better than 4 core since so many blades and cores stuffed into so little space just didn't have enough dissipation, are fletcher ratiators good? What radiator would you recommend.
I've fitted a 8 inch sucker turbine under the wheel well to help with hot air extraction from the ratiator, it's wired to an arduino that detects speed using GPS and when the speed is under 5Km/h it activates the turbine, I'm not really sure the difference was measurable since temps seem the same with or without.
I'm contemplating adding a intake fan on the front grille and removing my current install, or should I remove the mechanical fan and add a thermostatically controlled electro fan as my only cooling source? seems like most heating issues arise when minis are simply sitting in traffic, I've also heard of people altering the fan bearing diameter to make it spin faster, or changing from a 8 blade plastic fan to a metal 6 blade, there's so many options I don't know where to start.
Any insight or recomendations are highly apreciated!
