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.
Please rate and god bless.

SOURCE: what is the quickest way to change a thermostat on

Hello Kalel6877...the "quickest" way is let a shop put it on a hoist and do it...but if you want to tackle this one i'll walk you through it.
Raise your Dodge Intrepid with a jack and lower onto jack stands, or use wheel ramps. Set parking brake and/or chock wheels
Disconnect the negative cable from the battery. Open the drain plug at the bottom of the radiator and drain the coolant into a suitable container.
On Intrepids with 2.7L engines, follow the lower radiator hose to the thermostat housing. Loosen the hose clamp at the end of the radiator hose with a screwdriver and pull the hose off the thermostat housing.
Unbolt the two bolts holding the thermostat housing cover on and pull off the cover. On 2.7L Intrepid engines, it is easier to gain access to the thermostat housing behind the alrernator by working from beneath the engine.
Note the position of the old thermostat and remove. Install the new thermostat with the spring-side facing into the engine. Clean any old gasket residue from inside the thermostat housing cover. Install the new thermostat gasket.
Reinstall the thermostat housing cover and tighten bolts to 105 inch/pounds. Reattach the radiator hose and tighten the hose clamp. Refill the radiator with reserve or new coolant. Reattach the negative battery cable.
Start your Dodge Intrepid and allow it to run with the heater on high until it reaches normal operating temperature. Check radiator hose for leaks and tighten the hose clamp to stop any leaks, if necessary.
Thats about it...jack her down and pat yourself on the back.
Good luck..i hope this helps...please take time to rate me a fixya.

How do i replace the thermostat in a 1999 dodge intrepid?


It depends.If you have a 2.7L engine the housing is on top of the engine. If it's the 3.5L it's buried in the front and you may have to pull off the fan assembly to get to it.

Hi:
Your thermostat is located under the housing where the upper radiator hose connects to the engine. The housing is held to the engine with bolts,and has a gasket that must be replaced when you replace the thermostat. Make sure all surfaces are cleaned before reassembly.

Need to locate Thermostat in a 2001 Intrepid 2.7 L.


Follow the lower radiator hose to the engine. The thermostat is in the hose fitting on the engine. It is very difficult to get to, behind the alternator and above the engine mount. I changed mine about 6 months ago -- give yourself plenty of time if your going to do it yourself.
