Your van's thermostat allows coolant to circulate when the engine is warmed up and should be closed when the engine is crisp so that the vehivle can mild up faster. It's a quite inexpensive effects that's replaced easily, on the other hand when it fails, your van can overheat, causing costly engine damage.
Instructions
1. Clement up the vehivle nevertheless don't let it overheat--don't let the temperature gauge push into the cerise.
2. Turn off the engine.
3. Frank the hood.
Touch each hose very carefully (they can be extremely hot). If the temperature gauge is indicating that the engine is warmed up but one hose is hot and the other is cold, the thermostat is probably stuck closed, and the coolant isn't circulating through the radiator.7. Have the thermostat replaced if this is the case.
5. Locate the lower radiator hose. It looks similar to the upper hose except that it attaches to the bottom part of the radiator.
6.4. Treasure the upper radiator hose. It's black, is made of rubber and is about 2 inches in diameter, with metal clamps on either end. The upper hose goes into the top of the radiator.
