What precautions should be taken when removing and installing the thermostat to avoid burns and ensure safety on Honda Prelude?

While removing and installing the thermostat avoid exposure to high temperature steam and hot coolant, never work on the radiator or the cooling system with the engine running. Note that ethylene glycol used in antifreeze solution is poisonous to pets because of which it is advisable to store the coolant in a sealed container , and reuse it if not contaminated and /or expired. First, get acquainted with the radio security code and stations presets then remove the negative cable. To do so, wrap a sealable container with sufficient capacity to hold the engine coolant below the thermostat level and remove the tension from the clamp using the pliers then, remove the hose from the thermostat housing. In this step, the fasteners have to be unscrewed, as well as the thermostat housing, after which one has to take out a thermostat. For installation tighten thermostat housing with retaining bolts, while using new seal of thermostat, make sure that any small bleed is in the top position, and apply anti-seize compound on the thread of the fasteners. Connect the hose, tighten it with the clamp, turn on the heater to full hot and if the car has a 2.2L or 2.3L engine the bleed the coolant from the overflow hose at the bottom of the thermostat housing. The performance checks include a 50/50 blend of antifreeze and distilled water to avoid mineral buildup, fill the cooling system and the overflow, recover to remove air in the system while applying pressure to the radiator hoses. Check all the hoses and the fittings if they are properly connected and in proper position, shut the bleed valve if it is open, reconnect the negative terminal of the battery, and just fit the radiator cap loosely. Leave the engine to idle for approximately 10 to 12 minutes after which you get to hear the cooling fan to turn twice; shut off the engine and check on the level of the cooling system as required. Last, replace the radiator cap and check for some extra leaks if any before going further to input the radio security code.
