If frequ ent antifreeze/ coolant additions are requ ired ,
or if the level in the recovery bottle does not drop
when the engine cools, the cooling system shou ld be
pressu re tested for leaks.
Hoses and Vacuum/Vapor Harnesses
Insp ect surfaces of hoses and nylon tubing for evid ence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling ind icate deterioration of the rubber.
Maintain antifreeze/ coolant concentration at 50%
HOAT antifreeze/ coolant (minim um) and distilled
water for prop er corrosion protection of you r engine
which contains aluminu m components.
Pay particu lar attention to the hoses nearest to high heat
sou rces such as the exhau st manifold . Insp ect hose rou t-
ing to be sure hoses do not tou ch any heat sou rce or
moving component that may cause heat damage or
mechanical wear.
