Mopar 5184651AH Thermostat Housing Review:


The OEM replacement is flawless. Had an engine code P0128 appear, indicating that the thermostat hadn't closed properly and that the engine temperature was too low. Around 11:00, the needle typically runs just off center. The standard range for coolant temperature is between 190 and 200F. Uncertain about what occurred that morning. Perhaps it was a fluke. I just changed it because I didn't want to take a chance. super simple task You only need a 10mm socket and a flat-blade screwdriver. I believe that this part works with any 3.6L Pentastar engine from 2011 to 2015. Simply peel the decorative engine heat shield off by pulling it straight up. It simply snaps off.Unscrew the two hose clamps on the air intake, one at the intake manifold and the other close to the air box/filter. Take out and place aside. Because a quart or more of coolant will leak when the thermostat is removed, I used a small garbage can (or bucket) to catch it. To allow the coolant to flow into your bucket, loosen the hose clamp on the radiator hose that connects to the thermostat and wiggle it loose. The two bolts on the thermostat can be removed using the 10mm socket. It really started to pour here. Keep it from spreading everywhere. Reassembling is simply the opposite. Unsure about the bolts' torque. Just snug enough, I did. You don't want to lose your mind because it's only plastic. I refilled the system with fresh coolant by about a quarter and bled the line using the tiny bleeder valve located above the thermostat. You should be good to go if you just start the engine and loosen this small cap until it starts to leak. Just to be sure all the air was out, I repeated this procedure a couple more times. Since then, everything has been working perfectly, and it has been more than a month since I last noticed the code. Definitely recommend this stuff.



Dorman OE Solutions 902-852 Engine Coolant Thermostat Housing Review:


Exactly what I needed to replace my wife's 2012 Jeep Cherokee. After installation, the engine code was removed. The pieces might be changed out with ease. It only took a few seconds to find the instructions on YouTube. You will lose some coolant, so it's a good idea to have a fresh container on hand to top out your fluids. Additionally, you should bleed the line of air following the installation. Again, a simple process with an online guide. The animal has been there for around 6 months, and it still appears to be functioning perfectly. It cost me between $150 and $250 to complete the project, so doing it yourself was definitely worth the money and effort. Definitely a wise purchase.

Dorman OE Solutions 902-2009 Engine Coolant Thermostat Housing Review:


The finish is a little bit smoother than pictured, but else it looks exactly as I anticipated. The gasket in the picture was finally discovered to be loose within the box. This housing has two sensor ports, the smaller of which is 3/8 in diameter ". the 3/8" wrench's threads "I'm having some difficulty threading the fitting I purchased into the housing, and the port seems to be defective. With a little WD40 and a longer wrench, I believe those threads will function. Chinese made



Dorman OE Solutions 902-3036 Engine Coolant Thermostat Housing Review:


I was a little intimidated at first because this is a little different from the thermostats I'm used to. It becomes a whole lot simpler after seeing a video. Use a 10mm deep well with a 1/4" drive ratchet. The fasteners became loose enough to remove with fingers quite quickly. The hose should then be pulled out so you can release the clamp by moving it down the pipe from a better angle. Pull the hose apart by wrapping a small screwdriver around the area where it connects to the thermostat. Put in a new thermostat, swap out the clamp, and tighten the bolt. Don't forget to replace any lost fluids and look for the original seal. I test drove the 3.6 Caravan and was pleasantly surprised at how quickly it heated up.



Thermostat Assembly for GM Chevy Cruze Sonic Thermostat Housing with Sensor Gasket, 25192228 Review:


I thought a new thermostat would erase the check engine light's P0597 "CRUISE CONTROL CONTROL CIRCUIT/OPEN" code and turn on the heat after some study on the code and the fact that my heater had stopped working. I purchased this unit because it only cost an additional $10 to include a new housing and the Chevy Sonic thermostat replacement videos I had viewed had claimed it was simple to break the top hose fitting on the plastic housing. I turned out not to need the housing because I didn't damage my old one.However, replacing my old thermostat unit with this one cleared my check engine light and made my heat function once more (which I was glad for as we were experiencing freezing temperatures). When my tag expired a month later, I was also able to pass emissions because of this.Really hard to top this one's price. Even local part stores demanded between $80-$100 for the thermostat alone, while dealerships wanted to charge me hundreds of dollars for this fix.

Works well and is of high quality. This was quickly put on my wife's 2012 Chevrolet Cruze! Just so you know, before you start this job, make sure you can remove the throttle body heating line without damaging it. I did, however, run into a difficulty (not with the product). So just save yourself the time and hassle and purchase the replacement line before you change the thermostat casing. Mine had never been removed and was very brittle and broke.
