Just rebuilt my engine (1584cc, Engle 100, twin 34ICT's, electric fuel pump) and when I put the fan housing back on, I dabbed a bit of Tippex onto the end of the shaft that rotates when the flaps open (too much mention of shaft and flaps there ). This can be seen bottom right of the fan housing. The idea being I would be able to tell when the flaps were open or closed if the Tippex had rotated.
Anyway, took it out for a spin for around 10 miles tonight. Country roads then back through town. The mark hadn't seemed to have rotated as dramatically as I thought it would (there was a reference point on the fan housing so I could check where it started). I'm now worried that the flaps won't open enough and I'll run into over-heating issues.
How do others measure if the flaps/thermostat are working or not?
