Water pump failure, water pump on these run off the timing chain and the timing chain runs in oil, so they could not just put a weep hole on the pump because it would go strait to the oil pan, instead they redirected the coolant from the leaking pump to just below the thermostat housing. And good luck, it's at least a 6 hour job on these. Brandon-MO

How do I change the thermostat?


Follow the large hose coming out of the top of the radiator. That should take you to the thermostat housing. You need to place a container under the drain spigot on the radiator and drain a gallon or so of coolant from the radiator so that coolant doesn't run out when you remove the housing. Remove the housing (usually don't need to remove hose) and scrap clean both surfaces of the housing and the block. Take not of the position of the gasket and thermostat you are removing. Replace thermostat, put a small amount of gasket sealing material on both surfaces, put new gasket on and tighten the housing back down. Some engines have a small plug in the housing. You have to remove the plug as you replace coolant back into the motor until you see coolant running out of the hole and then put the plug back in.

Here is a video that show the gist of changing one.

How do you replace a thermostat on a 2002 toyota celica

The thermostat is located in the water inlet housing that is connected to the lower radiator hose.
The thermostat is equipped with a by-pass valve. If the engine tends to overheat, removal of the thermostat would cause a decrease in cooling system efficiency.

CAUTION NEVER drain coolant directly onto the ground! NEVER open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

Fig. The oil filter must be removed to access the thermostat on the 5S-FE engine
  1. Position a suitable drain pan under the radiator drain **** and drain the cooling system.
  2. On the 7A-FE engine disconnect the engine coolant temperature switch harness from the water inlet housing.

  6. Remove the thermostat.
To install:
  1. Install a new gasket onto the thermostat.
  2. Install the thermostat with the jiggle valve upward. It can be set within 10 degrees on either side of the prescribed position.
  3. Install the water inlet via the two nuts. Torque to 8 ft. lbs. (11 Nm).
  4. Install the generator assembly.
  5. Add engine coolant.

Need to replace a Thermostat on a 2001 PT Cruiser. Have the new Thermostat need insturctions on how to do the replacement.


Most thermostats are located in the upper radiator hose housing mounted to engine block. Make sure engine is cold put a catch pan under your car to catch any antifreeze that comes out. Remove the two bolts holding the housing on the engine and remove thermostat and gasket. Clean engine block where gasket goes very good and also the housing, have to remove all gasket material so when installing new one it will seal and wont cause a leak. Make sure when you put the thermostat back in it goes in spring side down towards engine. Replace housing and bolts. replace lost coolant with a 50/50 mixture in your recovery tank. Start engine let heat to temp and check for leaks.
