[Shotimes] Heater Core ?s.

[van Oss]

Heikki,

Paul's advice about refurbishing the heater hoses was good.

To replace the core, you have to at least dismount the heater box, if not
remove it entirely from the car.  This is not rocket science but it will
take a lot of time --- figure a weekend.  In my case, two.  You have to
dismount the steering column and dash, and pull the dash rearward about a
foot.  Lots of bolts and screws --- make sure you have a system for keeping
them organized with information about where they came from.  The heater box
is mounted to the firewall with three studs, so you have to remove three
nuts on the engine side (two up, one from underneath).  If your car still
has a living AC system, it will  need to be evacuated, dis/reconnected, and
refilled.  Make sure you have a Helms shop manual.

If all this makes you think about taking the car into some shop, be prepared
for a big bill, because there are a lot of labor hours in this job.
Something like $800.

While you are doing the heater core, I would suggest you consider a new
blend-door motor.  Motor failure occurs regularly among older Tauri, and
like the heater core, it requires pulling the dash.

----- Original Message -----
The time has come for me to replace the heater core in my SHO ('93 MTX).  It
started blowing huge amounts of steam into my car yesterday morning so I was
forced to pull over and cut the hoses off the firewall and connect them to
each other.  This steam situation was all taking place with the heat off,
and only grew exponentially worse when I turned the heat on (I was just
curious).  I am wondering if this is the same core as the non-SHO Taurii,
and also if anyone has any suggestions or comments of experience.  Stay away
from these brands, don't be stupid and do this while installing it, etc...
CCing replies to my email would be appreciated.  Thanks again for the
expertise.
