If the level in the expansion tank falls, the two electrical contacts in the cap no longer conduct through the coolant. When this happens, the temperature light starts flashing. Interestingly, if the coolant mixture is wrong enough that it no longer conducts sufficiently, this too can cause the light to flash. And of course, if the temperature soars, the light flashes ... but who of us will admit to having ever seen the engine overheat to this extent.Larry '86 Syncro Westfalia |
