    Thanks, I have a bad heat overall, especially during winter time and when I drive like 50 m/h. When RPM is high or whenI drive D1/D2/D3 shifts or when car is inside garage temeprature picks up to about both on engine gauge (160F) and fan. But, when I drive like 50m/h temeprature on both engine gauge and fan goes down. On engine is like 140F and on winter time gauge is down completly.

Use a termo laser to check temp of coolant at filler cap ,with cap off run vehicle till you have hot heat coming out of your heater then check with laser. if it reads above 140 then you know 2 things . either the therm sensor is going bad or the temp gauge is bad , make sure the radiator fans come on ,if they do and you have good heat then you have bad gauge.

check engine means you have to check your engine and open your trunk first and then check the engine. Once you open and check the engine and check if the engine lights still on. it should disappear in no time. Thanks for the time

the temp sensor just tells you the temp of the coolant and it controlls the coolant fan to turn on and off at a certain temperature........have you check for coolant leeaks???

It does sound like the thermostat. The sensor does not control the thermostat in any way, it only reads the temperature of the coolant. Your symptoms are classic of a thermostat that is stuck open or partially open. Take it back and tell them what is going on and have them show you that the thermostat is fine.

PO172 means that an oxygen sensor in bank 1 detected a rich condition (too little oxygen in the exhaust). I would replace the thermostat first. The computer could be injecting too much fuel because it thinks it never gets to operating temperature. That may keep the light off.

Whenever i get this code i like to clear it and see if it returns. Sometimes in extreme cold weather conditions it will set this code and there may not be anything wrong. What motor is in your celica?

2004 honda pilot how to replace the thermostat

You can test to see if it is the thermostat by running the vehicle allowing the coolant in the engine to become hot. Then squeeze the top radiator hose. You may want to use gloves to protect your hands. If you feel a lot of resistance in the hose in the direction of the engine then it is likely that the thermostat is stuck. To replace the thermostat remove the two bolts that secure the thermostat cover. They are located where the top radiator hose connects to the engine block. You can also verify if it is defective after removal by dropping it in boiling water and seeing if it opens. The correct temperature for it to open is usually written on it. They are not that expensive so it is best to use one from the dealer. Regardless, make sure it is designed to open at the same temperature. The assembly (thermostat/gasket) is number 5 in the image below. Just google part#19301-P8E-A10

Honda Pilot 2003 temperature gauge gets only quarter way hot, and on highway it gets very low. Cabin fan temp is low too. Thermostat and was replaced several times. Cooling liquid was replaced too.

Sounds like you have either low coolant, due to not properly bleeding air from it when the coolant was changed, or the thermostat is not working, or possibly not right for the vehicle. (Honda's typically don't like aftermarket t-stats because they don't work as efficiently as the factory ones. And most are missing a bubble bleeder for air to pass through. (the little ball valve in most t-stats) You should also see if the cooling fans are stuck on all the time. They should cycle on and off fairly quickly as the switch calls for them. Air bleeding is critical as you have a large system with an aux. rear heater unit too. Even a relatively small air pocket trapped inside can wreak havoc on the operation of all related systems.

Caravan does't reach operating temperature

No one ever said new means good. Try another thermostat. Make sure it is the recommended temp for the vehicle. I would spend the extra money to buy a dealer thermostat. What controls temp is restriction of flow thru the system until a set temperature is reached and the thermostat opens. Has to be a thermostat.

2003 chevy cavalier with no heat and temperature doesn't rise past 40 degrees engine code P0128 comes up when checked and the thermostat and radiator have been replaced still isn't fixed what do i do?

A code P0128 may mean that one or more of the following has happened:
  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty cooling fan (running too much)
  • Faulty coolant temperature (ECT) sensor
  • Faulty intake air temperature (IAT) sensor

Check engine light, and engine temp gauge drops. Otherwise car is running well.

If the thermostat is stuck open, the engine temperature will drop and set a fault code indicating that the engine is not reaching operating temperature. This will cause your check engine light to come on. Have someone scan your engine computer. Most large parts chains will scan for codes at no cost to you. If there is a "Thermostat" or "Engine temp low in closed loop" or a similar code indicating low engine temperature, replace the thermostat.

Honda didn't make the Pilot until 2003. Check th year. On the 2003 model you can find it on the driver's side of the engine where the lower radiator hose connects at the engine. Hope this helps,...ZMANRACING

2003 CR-V; Hot temperature gauge

Kind of, it's over heating, probably do to a stuck thermostat in the closed position, have it replaced, and if you keep driving it with it hot like that, you can end up with serious engine problems.

1997 Honda Odyssey thermostat

Honda recommends that the cooling system be topped up with coolant four times as part of the refill process. When the engine is fully cold open the radiator cap and add coolant until full. Run the car until fully warm with heater at maximum. Let it completely cool down. Remove radiator cap and top up with coolant. Repeat this process two more times. This helps purge the air out of the nooks and crannies in the cooling system.
