Hi, 

 

 

One year ago I installed an high lift rocker set . I'm very happy about this but in summer here (south of France) the engine slightly overheat when I climb big hills so I go easy (4000rpm max) and this is fine but I would prefer to push a bit more... 

 

I'm considering to install an aluminium radiator instead of my 3yrs old standard one. 

 

Do you have experience with aluminium radiator ? 

 

92' Mini cooper 1275cc with carburetor, full stock except the rockers. I already have an electric fan thermostatically controlled. 

 

Thanks,

aluminium does not transfer heat as well as copper. make sure you only have as much anti freeze in as needed. make sure the fan is fitted correctly. is your fuelling correct with the changes.

Change the coolant and flush the hoses. Also keep the heater and fan wired in too, it's effective at removing heat
