I suggest replacing the thermostat, that might work.
The heater cor was replaced but it is still not getting warm
== ==
it's leaking coolant. Needs to be replaced.
The engine coolant level is low or needs to be flushed, and replaced.
It connects to a heater hose behind the engine.
Your 1992 Lincoln Town Car takes 2.5 pounds of R-12 refrigerant or 2.75 pounds R-134 (if system converted)
There is a resistor/ circuit board near the heater motor that need to be replaced. You can get one from almost any auto parts store.
How do you bleed the heater after changing coolant in a 1992 4runner
There is no such thing as a 1992 Lincoln LS
Per the owner's manual, the 1992 Lincoln Town Car's coolant capacity is 14.1 U.S. quarts (just over 3.5 U.S. gallons), including heater capacity. That is for the standard 190HP 4.6L V-8 equipped on most models.
I need to know how to replace a heater core in a 1992 GMC Jimmy?
$52- $208 roughly. depends on if the heater core is bad.
