Get real close and eyeball the hoses for any wear marks. These hoses rub against
the seat. Too much wear means a hole with coolant leaking out. Without coolant,
there’s no air conditioning. Talk about hot tempers in Southwest Asia!
See any rubs? Use a 6-in tie-down strap, NSN 5975-00-984-6582, to hold the
HVAC hoses in place away from the seat. Place the strap on the hoses about six
