The thermostat may be in backward (it does happen), or your thermostat was bad and stuck shut. Either way, you need to pull the thermostat and take a look. Don't forget to replace the gasket. Hope this helps

Almost sounds like you put thermostat in backwards. Sorry, it happens to the best of us and yes it's possible.

Where is thermstat


Assume you are asking about the thermostat. You can find it by tracing the radiator hose to where it connects on the intake manifold. The piece it connects to is the thermostat housing. The thermostat lives inside that housing.

Want to know whats these codes mean [Engine rpn 704 rpm],[Map sensor 45 kpr], [cool ant temp 141f], [Dtc t caused rreezerrame p1281]. for a 2000 grand cherokee


Hi, the first part is data taken along with the code. The code P1281 indicates the engine is running cold (141 degrees--should be at least 190). Is your temp gage running lower than you are used to? If yes, it may be your thermostat has failed open. I have pasted below instructions for replacing the thermostat. Please let me know if you have any questions, and thanks for using FixYa.

How to replace a thermostat


2.0L Engine
SOHC ENGINE
(see Figure 17)
  1. Disconnect the negative battery cable.
  2. Remove the air cleaner outlet tube.

CAUTION 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.
  1. Drain the cooling system until the level is below the thermostat.
  2. Unplug the coolant temperature sender and coolant temperature sensor electrical connections.
  3. Disconnect the upper radiator hose and heater coolant hose from the thermostat housing.
  4. Unfasten the thermostat housing bolts.
  5. Remove the thermostat housing and the thermostat.
  6. Clean the gasket surfaces thoroughly until all traces of the old gasket residue are removed.

Make sure the tabs on the thermostat engage properly into the slots in the housing.

  5. Attach the coolant temperature sender and coolant temperature sensor electrical connections.
  6. Fill the cooling system.
  7. Install the air cleaner outlet tube.

Where is thermostat on 2000 kia sephia runs hotter as rpm's increase runs a little cooler as rpm's decrease no coolant leaks 1 of the 2 fans is running when hot


Follow the upper radiator hose from the radiator to the engine block. Where it connects to the engine is where you'll find the thermostat. It's under a housing...should be two or three bolts holding the housing down. Don't forget to replace the gasket.

    98 ford wind star running hot


    Warm the engine up to operating temperature. Does the upper radiator hose get warm? If no, then cange the thermostat. If yes, then the thermostat is working fine. On the thermostat housing, there is a sensor. Some engines have 2 sensors. One goes to the computer and the other goes to the temp needle in the dash. Unplug the harness and put a jumper wire in the harness. Turn the key to on, and see if the temp needle goes up. Which ever harness causes the needle to go up, replace that sensor. Hope this helps.
