A couple of months ago i replaced the rear heater matrix,re plumbed it in and got my air-con fixed and regassed.
Since all this was done i seem to have a more varying temperature reading on the secondary gauge which is fitted to my van.The mazda gauge always sits at 11 o`clock.
The sensor is tapped into the small bore hose that goes into the expansion tank.
The temp seems to sit around 76-78 degrees when moving and the bottom hose to the radiator can often be "just warm" and not "hot".
The heaters always blow hot when turned up and to be fair the van runs fine.
I have never seen the gauge drop below the 76ish mark when moving.
If the stat was at fault it would either be cold or overhating??
Can this fluctuation be caused by me always using the air-con as the fans cut in and out?
When the rear heater was bypassed and the air-con did not work the secondary temp gauge always sat at around 82 when moving,only rising when stationary.
Hopefully its nothing to be of concern and it deffinately would not have been noticed if the secondary gauge was not fitted as the Mazda gauge always sits at 11o`clock.
Thanks in advance for any replies.....
