Hey guys my 800 fan always kicked in at 204 degrees and would drop quick back down to 188 now it kicks on at 205 but keeps climbing to 208 before dropping I have just changed water pump seal and definitely no air in the system is this normal

Yes I have . And I also just unhooked it and hooked up directly with no change . If I'm riding along the fan cycles fine comes on at 205 and goes back down to 194 but it goes to 206 for a little while before dropping . And when I first stop the fan will come on at 205 but the temp keeps creeping to 208 210 before coming down to 194 . It always came on at 204 and would never go past that at all and would drop to 188 I'm lost

i have this weird thing happening to. cruising and normal driving, regardless of whether I'm in high range or low, are fine. when I'm cruising in high and then come to a stop, the temp spikes up until i start moving again again regardless of whether or not i take off in high or low. on long rides, after i stop to get out for a minute, I've noticed when i turn the buggy back on that my gauge reads much higher. up to around 215 and as soon as i start the buggy back up it drops right back down to 190's. its very weird and not consistent. I kind of wish the cooling systems were better.

I never worry about the engine temp as long as it's between 180-220° this is the operating range of a pressurized cooling system most thermostats do not open until 190° releasing the coolant to circulate thru the radiator
Water boils at 212° pressurized water boils at 220-230° depending on the system pressure (radiator cap psi)
One or two degrees various isn't a concern as long as the fan comes on and cools it down to thermostat dregees
PS: you don't want your coolant boiling in the engine that's the reason for pressurizing the system to raise the boiling point
