Recently I got a code for my Thermostat Heater Control Circuit Low & Open, so I purchased a new thermostat w/housing and I realized that theres no how-to write up for the swap. Anyhow, here's my write up, with a couple pics from my Note 4.
- Torx socket (I believe T20-T25, I'll double check monday)
- Hose Pliers
- Needle Nose Pliers
Now, first off you need to drain your coolant (of course), thankfully all I had to do is remove my bumper and drain it without jacking my car up, even though I'm lowered. The drain nozzle is located underneath the passenger headlight on the bottom of the radiator, as seen in the pictures below. Be careful when un-screwing, as there is a bleeder nipple pointing towards the rear of the car, and some coolant will pour out of the nipple while you're getting unscrewing the last half of the threads.
Next step, is to remove the upper radiator hose from the thermostat housing. Use your pliers to move the spring clamp and pull the hose off:
After that, un-do the two Torx bolts holding the hard pipe feed from the thermostat housing:
With the hard pipe undone, unscrew the 4 main bolts that attach the thermostat housing to the engine block followed by the two clip on sensors:
Last of all is this pesky temperature sensor on top. In order to get this thing off you need to unscrew it, while giving a slight pull until it comes out. once its out, simply reverse the steps and install your shiny, brand new thermostat housing & thermostat:
Sorry for the lack of pictures, if you have any questions or want more pictures post below and I'll update the thread Monday night. Have a good one, and I hope this helps someone out further on down the road!
