"COOLANT THERMOSTAT" -COOLANT TEMP BELOW THERMOSTAT TEMPERATURE
First check the water level. Low level will not get to the heater core. Change the thermostat. If you recently changed the thermostat, bleed the coolant system.
Check coolant level Water pump not circulating coolant? Radiator plugged or restricted? Cooling system airbound? Thermostat not opening?
Remove the thermostat housing screws and separate the housing, exsposing the thermostat and coolant, remove old thermostat and gasket. Reinstall new thermostat, gasket and coolant.
the thermostat is in the coolant cap
where is the coolant system thermostat on a ford focus 1.4 zetec engine
If the pump is not circulating coolant insure that the thermostat is not stuck closed. If the thermostat is ok then the pump will have to be replaced.
Yes it can. A faulty thermostat can cause overheating which will cause coolant to be pushed out of the system.
Usually this is not the case. It looks like a bad thermostat, because no way the coolant is not getting hot, but a rusted up thermostat would not open for the coolant to circulate. If I were you I will change the thermostat first than check the water pump.
Low coolant? Plugged or restricted radiator? water pump not circulating coolant? Thermostat not opening fully? Defective radiator cap? Hoses collapsing under pressure?
The thermostat in a car regulates the coolant temperature inside the engine. When the engine is cold, the thermostat is closed, allowing the heat from the combustion chamber to heat the fluid (coolant) in the coolant galleys in the engine block. Once the engine reaches an optimal temperature, the thermostat opens, allowing coolant to flow through the radiator. The thermostat then controls the flow of coolant to hold the engine at its optimum operating temperature, irrespective of engine load and operating condtions.
When changing the thermostat on a Nissan 300zx first drain the coolant from the engine. Then find the lower coolant hose on the radiator. Trace the hose to the thermostat housing. Remove the housing to uncover the thermostat and replace the unit with a new thermostat.
When you start the engine, the thermostat is closed. After the coolant warms up the thermostat begins to open up allowing coolant to flow thru the raditor. When first started the temp will go a little past what the thermostat is set to open at. After the water begins to flow thru the radiator, the temp will fall to whatever the thermostat is set at. The thermostat holds the coolant in the engine until it warms up. As soon as the engine is warm, the thermostat opens allowing cold coolant outside the engine to mix with warm coolant. The temp drops, the thermostat closes again, until all the coolant is warm.
No thermostat, no coolant, no waterpump. Basically you have no coolant circulating.
You need to first drain the coolant, to lessen the mess of spilt coolant. Next you have to unbolt the coolant neck at the block to access the thermostat. After replacing, you have to refill/bleed the coolant system.
No, you will not have to drain all the coolant to change the thermostat on a 1999 Dodge Grand Caravan. Only the hose that is connected to the thermostat needs to be drained.
The temperature of the coolant entering the heater core is controlled by the engine thermostat. The engine coolant thermostat is generally located at the engine end of the upper radiator hose.
A sticking thermostat is caused by wear. The only option is to replace the thermostat.
Trouble code P0128 means: Coolant Thermostat (Coolant Temp Below Thermostat Regulating Temperature)
When the car is cold the thermostat is closed. When the thermostat is closed the coolant does not circulate or get in to the engine block.
The normal direction of circulation in the coolant system would push the coolant out the thermostat opening.
Tools a new thermostat and gasket and coolant
A faulty thermostat in a 2001 BMW 325CI can cause a coolant leak. The coolant may be leaking out a crack in the thermostat or through a warped edge. In some cases the problem may be just a bad gasket and not actually a problem with the thermostat at all.
