hi all i have just rebuilt my engine after having the cylinder plated went for my second ride since rebuild after about two hours noticed fan not working i was just about to pack up for the day when the water pipe from the top of the radiator to the cylinder blew out. almost shat meself any ideas on what would cause this cheers

er ,the fan not working

Sounds like the fan module has gone - are you sure you hooked everything up right after the rebuild?

as above , the sender is favourite. join the conectors to check the wiring and motor

Replace the pipe and refill the coolant and see if it still starts. If it won't go, you may have damaged the O ring between the barrel and the head.

Once you've got it running, simply connect the two wires fromthe sender together and see if the fan still works. If it does, you will need a new sender. Then check the coolant again to make sure there's enough in there.

Good luck.

fixed it needs a new temp sender seems to run okay now

thanks all
