If frequ ent coolant additions are requ ired , 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 coolant concentration at 50% ethylene glycol
antifreeze (minim um) in water for prop er corrosion
protection of you r engine which contains aluminu m
components.
Pay particu lar attention to those hoses nearest to high
heat sou rces such as the exhau st manifold . Insp ect hose
rou ting to be sure hoses do not come in contact with any
heat sou rce or moving component which may cause heat
damage or mechanical wear.

Make sure that the rad iator and coolant bottle hoses
are not kinked or obstru cted .
Keep the front of the rad iator and the front of the A/ C
cond enser clean.
Insu re nylon tubing in these areas has not melted or
collap sed .
Do not change the therm ostat for summer or winter
operation. If rep lacem ent is ever necessary, install
ONLY the correct typ e therm ostat. Other designs may
resu lt in unsatisfactory cooling perform ance.

Insp ect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
•
Increasing engine speed at idle does not red uce cool-
ant tem peratu re! Put transm ission in NEUTRAL and
let engine idle at norm al engine idle speed .
Com ponents shou ld be rep laced immediately if there is
any evid ence of wear or damage that could cause failu re.
