The heater core under the right side of the dashboard may leak engine coolant which can puddle on the passenger front floor. The loss of coolant may cause an engine overheating condition. Our technicians tell us that removal of the dash board is necessary to replace the heater on these vehicles.

1991 Bravada heater core one of the easier ones I've replaced - no n eed to remove the dashboard' just some stuff above the floor on the inside right.
Air Flow coming through vent is Great but blows out cold air only and i do also smell that sweet maple smell and my windows constantly fog up floor is not soaked but wet (honestly thought it was due to all the snow melting from shoes)But nope it smells like syrup- most likely need a new heating core..Correct?? any thoughts would rock thanks
replaced heater core still wont blow hot air
Turn defroster or heat on, truck leeks coolant and stairs out
Smell of radiator fluid when running heat. Took dashboard out, opened heat box and put in new heater core.
LOVE THIS CAR HAS BEEN A FAITHFUL COMPANION. HAVE FLUID FROM HEATER CORE A SWEET SMELL AND NO REAL HEAT IN WINTER
This has went out three times now. What is going on. It will heat and be fine then we end up with coolent leaking on the floor and a mess. Replace the core and it is fine again for a while. Then hear we go again. I am getting ready to replace it for the third time
