I seem to remember that unleaded fuel needs to run hotter to burn with maximum efficiency, so that may be why it runs so much hotter than seems sensible. The extra efficiency of the front mounted radiator may also play into that.

The MPI's do seem setup to run hotter than you would expect.
I've had to trouble shoot a couple and discovered that the boil over point is only around 5 degrees higher than 105c when fan is supposed to kick in.
Settings seem way too close to disaster for my liking but that's how they made them. I guess higher temp to reduce emissions was the goal.

Good grief, thanks MPlayle, should have known it would be in a manual somewhere. That seems awfully hot, but I suppose rover probably knew what they were doing.. I know I haven't let it idle long enough to see that sort of heat. May pull the sensor and try heating it up another way to verify its all working.

According to the Haynes manual (1969 to 2001), the front mounted MPI fan comes on at 105C (221F) and off again at 98C (208F).
(See the "Specifications" section at the start of chapter 3.)

805 Minis.. I had some trouble in the past.. I just hot wired the fan to runs all the time.. you can buy after market fans from Rimmer Bros in the UK.. or on ebay.com for about $50.... PHD>.

Tuning up a nice little MPi but unsure if the electric cooling fan is working properly. Runs great and stays cool while driving, but at idle without any airflow Im not sure how hot I want to let it get. If I unplug the temp sensor in the thermostat housing, the fan kicks on, I assume due to a safety limp mode thing in case the sensor or wiring were to fail. I've let it sit and idle until I got a reading of a little over 200F using an ifrared thermometer and the fan has yet to come on on its own. Normal? How hot should I expect it to get before the electric fan kicks on? The sensor itself is a new OE unit.
