Tiny coolant leak.

[Glynn123]

Sounds like where my overflow hose goes to from the expansion bottle, is expansion bottle full? If not are hoses running to it loose?

@glynn123 I'll have a check of the hoses. i've been topping it up so that it doesn't run low on coolant.

[Glynn123]

@sgt-robuck-5 likely just spitting it out since its overfilled, fill the radiator up but have the expansion bottle with just a bit in the bottom, one it's hot the level will rise and should sit between the markings

@glynn123 oh really? so me putting to much in could be the problem! makes sense i'll leave it for a little while and see how it goes

@sgt-robuck-5 mine used to leak under the seat and that would easily run down the frame to the kickstand

[Sgt Robuck 5]

Found out for sure that it was the coolant overflow. Used a cooling system pressure tester and the overflow pipe on the expansion tank sends it through the frame and out the bottom towards the kickstand and further underneath the frame. Didn’t realise the coolant was dumped through the frame.

@sgt-robuck-5 someone has forgot to bleed the cooling system I see

[Sgt Robuck 5]

@irongamer727 wouldn’t all the trapped air go out The expansion tank when the engine has been left running and then it would suck the coolant from the expansion tank in?

[Glynn123]

Mine seems to overflow out the left of the frame along side carb, as when the headgasket went a couple weeks ago it sprayed hot coolant all down my leg

[Irongamer727]

@sgt-robuck-5 doesn't work like that. Air pushes coolant up in the expansion tank filling it and then spits out on the road. Then returns to normal once cool. Just open the radiator cap and bleed it, problem solved.
