Hi all, I did an oil and filter change yesterday, took it for a decent ride on the highway to check for any leaks etc. and everything was fine. I went for a ride with a few old mates today up Mt Mee here is QLD and she started to over heat. Now this si where she gets the most work out so I always watch the gauge, but this time it was the coolest day yet this year and i watched as the temp slowly kept rising so I pulled over to find that the overflow was bubbling! and WHITE smoke was coming out off the oil overflow (i think its the oil overflow). I figured this was because I may have out a little too much oil in after forgetting to account for the new filter but this problem quickly solved itself after spewing the excess oil out - sitting at a perfect level now. After playing with it for a while I noticed the radiator fan wasn't turning on at all. Fuses are all OK and wires seem to be fine. Has anyone had this problem before? Could it be the thermostat and if so how do I test it?
