Does anyone know what the inside diameter is of the small coolant hoses on the FD? These are the hoses that come off the main outlet to the radiator of the thermostat housing.
Cheers,
Nik
I think they are 13mm, but I\'m going on memory!!
Cheers - anyone else know? 13mm sounds a bit big to me, but i\'m unsure.
I think from memory the inside diameter is approx 9mm, I took the old pipe to Pirtek to match!
