temp gauge

[nismo-400R]

hi,
i was driving the r on the motorway yesterday and noticed that my temp gauge would keep movin between c and to the middle and then sometimes it would just read cold but on normal driving it seems fine,anyone else had this?or any ideas what it could be?thanks

Thermostat not closing, you need a new one

could also be a dodgy temp sender on back of engine, single black and yellow wire with metal push on connector. 12mm socket/spanner to remove.

its after i put new rad hoses on like the samco's i noticed it wasnt doing it before though,

probably not bled the system properly

but its blowing hot air and fan is working

Well its the only thing that could have changed since you replaced the hoses. The temp sensor isnt near the front hoses so dont think you would have disturbed that.

i deffo didnt disturb that,its a strange one
