with a new thermostate our 306 now sits at 80 degrees for normal flat road useage.
your has thermostate out and sits at 85 ish.....and looses coolant.
I presume it normal state of tune or has engine power been increased.
engine has good power so probably not a blocked exhaust, does the exhaust "fizz" when an assistant presses the throttle pedal and you look/see/hear the tail exhaust??
with no thermostate in, and exp tank cap off ( can you post a pic of the underneath of the exp tank cap please ) and full, rev engine, does the coolant level go down?? so has circulation and its probably not the coolant pump, stay the same, or even go up ( goes up, blocked rad?? ) .
when hot are there cold patches on the rad core ( blocked rad core ) and does the heater work.
how much bubbles comes up in the expansion tank?? when revved??
do you fill exp tank, then drive, and then see coolant level when cold? is it below the max coolanl level "bridge" inside the exp tank, which makes you think it looses coolant??
does the low coolant level indicator work when the tank is low on coolant.
