More common reason: you have an old-style coolant-level controller as found in roughly pre-'85 vans, and it has triggered. Could be a bad controller (and anyway you'd rather have the newer, cube-shaped one which will cause the light to blink without visibly affecting the needle), but more likely it's an open in the wiring of the level sender (the plug comes to mind) or the sender itself which is just two s/s pins sticking down into the pressure bottle. Scrub the pins with ScotchBrite, check/clean the connector, make sure the ground is good. If you're running a very weak coolant mix that could conceivably cause this as well. Sight unseen my bet is on the connector at the pressure bottle. Yrs, d |
