Does anyone know the inside diameter of the coolant hose going from the bottle to the engine on my IQ600 Shift? I want to install a temp gauge and I want to make sure I get the right size adapter. Which would be best 16mm or 19mm?
Did you get rid of your gauges. That function is already present or are you trying to see what return temps are?
I have these adapters feeding my turbo in the thermostat line and line feeding the water pump (biggest hoses in cooling system) and they are for 1" ID hose
