My intent is to add in a coolant pump for more even heating, just wanted to confirm that it's 19mm hoses that run to it. Thanks!

There's an OEM version that goes for about $350 CAD... but i can get the pump for $80CAD and don't mind bodging a little.

Any input folks? Just hoping someone could measure the diameter of the coolant heater inlet/outlet during an oil change and let me know. If not I’ll measure it next time I can and post here. Thanks
