Oiwa Garage Tech Note

"This is the radiator water inlet hose. Bleed the cooling system after the hose job so no air pocket sits at the thermostat and cooks the engine."

Frequently Asked Questions

Can a collapsing hose cause overheating?

Yes - a hose that sucks flat under suction chokes coolant flow and overheats the engine, so replace a soft hose promptly.

Do I need to bleed the system after?

Yes. Refill and bleed the air out so the cooling system works and the engine does not overheat.
