Hi my temp gauge goes to half way then just after the fan kicks in have these got a 2 stage fan if so then this is deff stage 2. But today the red light came on I tapped the box next to the fan and it kicked in again fast and loud??
Heating issue

#1

#2Sticking relay perhaps? and you tap it and it starts working again?
You've got other problems if it needs full speed to keep it cool. maybe air lock or a sensor going bad? -
#3Cleaned relay. The fan kicks in just after half way but still as fast as it can go
-
#4Drain refill & bleed the cooling system,if that doesn`t work try another fan motor.
