Driving without a heater connected

[jagnut66]

Hi, 

Whilst my heater matrix is away being recored I was intending to run the car without it, by linking the two pipes at the back of the engine that normally connect into it, creating a loop.

Which considering that the heater must have been pretty much bunged up with crud anyway, might be an improvement (temporarily).

I think this should be okay but just wanted to test the water (no pun intended) and see what others thought.

My main reason of course is a desire to attend the joint MG / triumph weekend, this Saturday.

I doubt the matrix will have been done by then.

Best wishes,

Mike.

Yes, sure, no problem at all with bypassing the heater like that. My GT6 was so configured for some time before I bought it (and a little while after - I didn't need the heater any more than the PO did!)

or just block the 2 heater pipes which is basically the same as having the valve closed

I did this on my 13/60 and noticed the gauge read noticeably warmer, presumably because too much water was bypassing the radiator.  Ended up shoving a suitably sized bolt into the pipe to reduce the flow down and it was fine again.  On the other hand, my first Vitesse was plumbed in without the heater when I got it and that didn't run any warmer than when i reconnected the matrix.

Same here when I bypassed it for a while

Optional extra, for good reason, on a GT6 Mk1 so should be no problem.
