    Quick facts

    • Part: Dayco 80400 heater hose
    • Also called: HVAC heater hose
    • Fits: 1999-2013 Chevrolet Silverado 1500 V6 4.3L and other vehicles
    • Condition: New

    A hose that is cracked, swollen or soft, damp coolant at the ends, or a coolant smell in the cabin can mean the hose is wearing out. Weak heat from the vents alone does not prove the hose is at fault, because low coolant can cause it too.

    Fits

    Besides the truck above, the vehicles it fits include the 2005-2015 Toyota Tacoma V6 4.0L and the 2012-2014 Jeep Wrangler, among many others. A 2012-2014 Jeep Wrangler takes one.
