Jim Grant's Tech Tips
Q: I'm changing the heater core in
my Ford Aerostar. What tools do I need? Can't get the hoses off! It's
cold outside and the temperature is dropping. I blocked the hoses just
so I could use the vehicle. I would like to install the heater core before
it gets any colder here in BC, Canada. Any ideas?...Jed
to the world of specialized tools. It requires a special coupler release
tool to disengage the heater hose fittings that lock onto the heater core.
There is virtually no other method, short of destroying parts to remove
the heater hoses without this special tool. The tool you need is often
found at part stores, specialty suppliers (Snap-On or Mac tools) or can
be ordered through a Ford dealer.
