I have an 84 GL 1.9 and the temp guage continues to flash..? I just bought the van it has 90k on it .The previous owner just had the water pump and radiator replaced. Ok now when i first start it in the morning it starts flashing and goes right to hot any ideas? It also seems to be using coolant but i dont see any dripping or pooling under the van. I replaced the temp sensors in the back to no avail.... Any help or input will be greatly appreciated.....
