  Q: How to replace a thermostat in a cooling system on Acura Legend?

  A: To counter-check, check the coolant level, drive belt tension and the temperature gauge. In case the engine takes a long time to warm up, then its thermostat is probably stuck open. Put in a new thermostat. If your engine seems to run hot, reach over and touch the upper radiator hose with your hand. In case it does not feel hot but your engine is overheating, then most likely your thermostat is stuck closed so that no coolant inside goes to the radiator. Change the thermostat. Warning: Do not drive a vehicle without a thermostat because the computer may stay in open loop and this will result in emissions and fuel economy degradation. If the upper radiator hose feels hot it means there is flow of coolant through it as well as that the thermostat is open. Check troubleshooting section for cooling system diagnostic procedure.
