What is a tropical fan?

I might take my laser thermometer tomorrow and compare it to another mini, then I will know whether or not it is actually overheating.

The 6 bladed fan that the everyone on the interwebs thinks is the best fan.

I had a motor once in my mini which I could not stop over heating me and Warwick aguston were out of ideas rebuilt the head thought it might of been a valve and still over heated had a 4 core radiator with a 72 deg thermostat and a plastic fan and was boiling it self on a 40 deg day when I stopped then we placed a rubber strip the whole way around the gap between the rad and body and it helped a lot

That rubber strip is original equipment, so you did good...it allows the fan to make better air flow through the radiator

That rubber strip was deleted during the 60's because it did bugger all. It is a last desperate measure to try and disguise the real overheating problems.

Harsh!! I removed my strip once and saw what difference it made? No mush, but I had a good stable cooling system at the time...but you can really feel the air rushing around the rad rather than thru when its removed...

I took it for a run yesterday, I used the laser thermometer on the top radiator hose, it measured 70-74 degrees, the top radiator tank showed around 80 degrees. I don't have another mini to compare it to but I took my bluebird out and it showed a top radiator hose reading of 80-83 degrees. So, given that, maybe it isn't overheating at all?

Those temps are fine, however earlier you mentioned it reaching the mid 90s. This is ok, but mid 90s is on the warm side.

Are you having any side effects such as boiling off the water etc? Is the car running fine?

My money is still on it being the wrong temp sender?

Not only did they delete the rubber on later models they deleted the whole shroud off the inner guard.
It is a totally pointless exercise having it there. You don't get any extra air through the radiator from it.
If the purpose is to force every available bit of air through the radiator you would be much better off making an undertray to stop 90% of the air from going straight past the motor and under the car.

bahahaha!!!! what did I say???!!!!

so it took four pages to cure a non problem.. we should have listened to simon earlier

I always thought that the idea of the rubber strip would be to help direct all the hot air from the radiator out into the guard rather than let it circulate back into the engine bay. I imagine this would only make a difference in traffic.

I've also been told that it sometimes rubbed a hole in the radiator tank.

Certainly carves up the paint on the radiator in short time. I have a perfectly polished radiator underneath the rubber strip. No brass damage evident, but I wouldn't dismiss the chance.
