Car Forum / Chevrolet / Chevrolet Trucks / December 2004leaking heater core.
the last few weeks I have been smelling antifreeze when I have the heater on. Yesterday I checked, and the radiator was low on fluid. I've never seen a puddle under the truck, so I'm thinking that it is the heater core that has a leak (most likely a pressure leak). How difficult is this to change? '93 GMC 1500 w/ 4.3 I've never even looked to see where the heater core is located or how hard it will be to get to. > the last few weeks I have been smelling antifreeze when I have the heater > on.

VERY easy job. Shouldn't take you more than an hour. The HC is located just above the passenger's feet. The bottom part of the large plastic housing is held on by several small bolts; when removed the HC literally falls out. Doc |
