Hi all.. New here, but I can't seem to find any good suggestions for what to check next or if there is something I'm generally missing anywhere else online.
I've recently noticed that my GT125's temperature gauge creeps up fairly quickly into the red zone on every journey now after as little as 5 minutes.
The interesting thing with this is that the fan doesn't come on as I'd expect at any point, although I have tested the fan independently and it certainly works when connected directly to the battery.
The coolant has been recently changed using what I researched, flushed out and replaced with a recommended brand, and sitting at the max level nicely.
In an attempt to sort the issue too I've also replaced the temperature sensor (the one splitting the hose under the right hand radiator), and I've also changed out the themostat.
I'm assuming the water pump is working as expected, although I haven't fully tested this (as i'm not sure how without having to replace the coolant again), but the radiators are hot, which I'm assuming was a sign that the coolant was being pumped around somehow!
I also replaced the fusebox and all fuses in the glovebox, just to clean the thing up really as I'd noticed they were fairly corroded.
So.... would anybody have any idea as to something I could check next? Is there a relay i'm potentially missing somewhere in the circuit that might be giving me some hidden grief? Is there an easy way to check the water pump is functioning correctly without pulling it apart? or would the fan never coming on suggest it's maybe not overheating at all, and it could just be the gauge on the dashboard giving me the runaround?
Any thoughts, experience or ideas would be very much welcome!
