Depending on which "coolant level control unit" you have, IT can cause the temp needle to rise all the way if it is trying to signal that it has detected a low coolant level in the main tank. Normally it would also cause the led to flash if the led is working. Does it flash when the needle reads very high? Does it always flash for a few seconds when you first start the engine as it should? Sometime during 1985 model year Vanagons a new version of the coolant level low warning control unit was fitted. The 2 types behave differently but can be used interchangeably. The newer type does not peg the needle when it detects a low coolant level. It only flashes the led. The old type stops flashing as soon as the level goes up but the new type keeps flashing until the engine is turned off, even if you fill the tank. Mark
