I have a 96 Honda Accord that had the timing belt and waterpump replaced by a local mechanic back in August due to the Timing belt tearing up. I changed the Thermostat 1 month ago after having an occurance with the vehicle overheating. Then it still would overheat. I took it to a different mechanic who replaced the (blown) lower radiator hose. The problem is I still have excessive Coolant loss (minimal under the car). Please help. P.S. My fan does not kick on when my car is running with a high indicator on the Temp gauge on the dash, but as soon as I turn the vehicle off the fan kicks on.
