4.6l. Why does it keep overheating?

SOURCE: Overheating

Hi. I have put together a guide to help you with this replacement of the thermostat.


Step1 Raise your DodgeIntrepid with a jack and lower onto jack stands, or use wheel ramps.Disconnect the negative cable from the battery. Open the drain plug atthe bottom of the radiator and drain the coolant into a suitablecontainer. Reuse the coolant if relatively new and clean. Step2Follow the upper radiator hose to the thermostat housing in all enginetypes except the 2.7L. In Intrepids with 2.7L engines, follow the lowerradiator hose to the thermostat housing. Loosen the hose clamp at theend of the radiator hose with a screwdriver and pull the hose off thethermostat housing. Step3Unbolt the two bolts holding the thermostat housing cover on and pulloff the cover. In 2.7L Intrepid engines, it is easier to gain access tothe thermostat housing behind the alternator by working from beneath the engine. Step4Note the position of the old thermostat and remove. Install the newthermostat with the spring-side facing into the engine. Clean any oldgasket residue from inside the thermostat housing cover. Install thenew thermostat gasket. Step5Reinstall the thermostat housing cover and tighten bolts to 105inch/pounds. Reattach the radiator hose and tighten the hose clamp.Refill the radiator with reserve or new coolant. Reattach the negativebattery cable. Step6 Start your DodgeIntrepid and allow it to run with the heater on high until it reachesnormal operating temperature. Check radiator hose for leaks and tightenthe hose clamp to stop any leaks, if necessary.

• Removethe alternator drive belt and bolts holding the alternator in place andset the alternator aside for easiest access to the thermostat in DodgeIntrepid 2.7L engines, if desired.
• Don't drain the coolant from your Dodge Intrepid while the engine is hot.

SOURCE: cooling system and thermostat location. having

first look to see if anything is blocking the radiator on both sides that may be causing limited airflow. if nothing is blocking the radiator make sure the fan works. let the car warm up and wait to see if the fan turns on when it starts getting hot, but dont let it overheat. if the fan does work then it might be a stuck thermostat. the thermostat is located on the back side of the engine below the exhaust manifold. there is a downpipe for the radiator and there should be two bolts the you have to take off and the thermostat is between those two pipes. if the thermostat is replaced and you still have a problem with overheating it could be internal and i would suggest having it looked at as soon as possible. hope this helps and good luck! i had the same problem and mine was the thermostat. oh and one more thing, if you are going to change the thermostat yourself i would recommend putting the car on ramps at the very least due to the location of the thermostat. i had a lift which makes things a lot easier, but i think that ramps would do.

SOURCE: 1993 Lexus ES300 keeps overheating. I was told by a mechanic that I need to locate and replace the thermostat. I've purchased a new thermostat. Can anyone help me locate the existing thermostat?

What LexusBuilder says is true, except that it's Possible to remove the Thermostat housing without removing any belts or anything else, if you take it easy...
