4. Briefly loosen the expansion tank cap to relieve pressure in the cooling system. Clamp the coolant hose to the air damper housing using a suitable clamp (do not use a vice). Then loosen the clamps and disconnect the hoses from the carburetor (see fig. 10.4). Be prepared for coolant spills - place a container under the hoses and cover the surrounding area with rags.
Note: If you do not have suitable hose clamps, please contact Chapter 1A and before disconnecting the hoses, partially drain the coolant.
