How do you bleed coolant on bongo?

To bleed the coolant on a Bongo vehicle, start by ensuring the engine is cool. Locate the bleed valve, usually found on the highest point of the cooling system, and open it. Then, fill the coolant reservoir to the appropriate level and run the engine until it reaches operating temperature, allowing air to escape through the valve. Once coolant flows steadily from the bleed valve without bubbles, close the valve and check the coolant level again, topping off if necessary.
