Triumph Repair/Heater Assembly


Can you please provide detail information on removing the heater assembly a 74 Triumph TR-6?
Thanks, Michael

Hi Michael,

No small job. You should have a service manual to do the job but roughly you have to remove the dash, the tunnel trim pads, vent hoses, heater hoses, control cable, wires from the switch including the ground wire and the glove box then you can remove the heater box by the one nut securing it to the bulkhead and the three bolts securing it to the plenum.

I am guessing you have a heater core problem? I would be sure it is not just a connection of a heater hose as this is a lot of work.
