Okei, hyvä tietää tämä.JAMANT kirjoitti: No ei, jos termarin lämpötila on merkitty 80°, se tarkoittaa että se on täysin auki tuossa asteessa (+- 2 - ?°, toleranssiheitto), aukeaminen alkaa joa aikaisemmin!!
Huoltomanuaalista luin seuraavaa:
Eli tämän kuvauksen mukainen termostaatti olisi siis merkitty 89°C(1) To determine if the thermostat is defective, it must be removed from the vehicle. Refer to Thermostats for removal and installation procedures.
(2) After the thermostat has been removed, examine the thermostat and inside of thermostat housing for contaminants. If contaminants are found, the thermostat may already be in a “stuck open” position. Flush the cooling system before replacing thermostat. Refer to Cooling System Cleaning/Reverse Flushing in this group for additional information.
(3) Place the thermostat into a container filled with water.
(4) Place the container on a hot plate or other suitable heating device.
(5) Place a commercially available radiator thermometer into the water.
(6) Apply heat to the water while observing the thermostat and thermometer.
(7) When the water temperature reaches 80°C (176°F) the thermostat should start to open (valve will start to move). If the valve starts to move before this temperature is reached, it is opening too early. Replace thermostat. The thermostat should be fully open (valve will stop moving) at approximately 89°C (192°F). If the valve is still moving after the water temperature reaches this temperature, it is opening too late. Replace thermostat.
(8) If the valve refuses to move at any time, replace thermostat.
