Hi, my van don't have the thermostat installed with radiator fan. Some mechanic removed it earlier to solve the heating issues. Now fan is direct (become "ON" when engine starts). Due to this, at night, when head lamps are 'ON' battery bear more load at start-up and vehicle don't accelerate until battery gain some power. Same is repeated when it come to halt on traffic signals or speed breakers. Now I decided to re-install the thermostat. Please let me know the specifications and installation procedure of radiator thermostat. As always, I will be thankful for your precious time. ______________________________________________ 2003 Sambar Van , EFI without Supercharger ______________________________________________
