Motorcraft RT1201 Thermostat Review:


This is the thermostat you need for your 1999–2003 Ford 7.3. I've been using a defective thermostat for three years, and after a particularly chilly journey, I determined it needed to be replaced as soon as possible. It doesn't need any additional seals and is simple to replace. In addition to this, I would advise purchasing a new housing (Motorcraft RH63). Additionally, now would be a good time to replace any upper radiator hoses that pass through serpentine belts with those that go around (Motorcraft KM4351).Channel locks, tools8mm and 1/2" socket wrenches, I believe.Sticky knifeScrewdriver, flat1) Drain around a gallon or two of coolant, and then squeeze the higher hose to determine when it is at the point where you won't cause a mess.2) Disconnect the top radiator hose.3) Remove the three mounting bolts on the housing.4) Remove the old one by prying it loose if necessary using a screwdriver.5) Remove debris from the sealing platform, being careful not to let it get into the coolant. 6) Install the new one, attach the housing, and tighten the bolts to 20 ft-lb. RTV is not necessary, although you can add a little if you like.7) To make it feasible to attach the upper hose, spray the housing with a little amount of (note the phrase "small") WD40.8) Fill the radiator with coolant, test the vehicle, and look for leaks.



Atwood 91447 Thermostat Assembly Review:


had a quirky hot water heater in a brand-new trailer. Dealer failed to repair it (they tried, said it was fixed but after I got it home it wasnt working properly). After some research on Google, I discovered that these thermostats are usually the cause of problems. Although the kit I got quickly improved things, it still fell short of my expectations in terms of performance.I took the Tstat side off, used Scotchbright pads to clean the heater's surface and the back of the Tstat, and then put it back on. Vola! functioning PERFECTLY.Overall, the kit is effective, but you must ensure that the surface of the tstat and the side of the tank are completely flush. If there is even the slightest amount of grit between them, it will behave strangely (short cycle, not start or not shut off etc).



ACDelco 131-151 GM Original Equipment Engine Coolant Thermostat Review:


My 2003 GMC Sonoma has some coolant system difficulties, which I have been gradually resolving. My temperature sensor just burned out, so I purchased this thermostat as a precaution. My Sonoma's 4.3L V6 engine and this gasket fit together well. The stock gasket is a little tiny, as others have noted. As my previous gasket was still functional, I just switched it out for this one, plopped it in place, and it fit perfectly. As I tested the engine last night after installation, it maintains a steady 200°F and scarcely varies by more than a degree under different loads. I can't speak to its longevity or durability as it was recently installed, but given that it's an ACDelco component, it should last another 100k miles.



Motorad 420-195 Thermostat Review:


I haven't installed it yet, but it seems to be well made. I was unhappy that it didn't come with a gasket because I had assumed that a thermostat always came with one.



Suburban 232229 161154 Wall Thermostat-Heat Only-White Review:


I purchased it for a buddy who does not have Amazon Prime but urgently required it. It replaced his old RV thermostat, which lacked an appropriate on/off mode. He endorses it. Now when the temperature drops below 50F, his heater doesn't turn on! Happy client. You might be, too. (This device, unlike a typical home thermostat, has a positive click-off position on the far left.)

For our leopard geckos, I have a number of thermostats that regulate ZooMed


Can you replace a thermostat with any thermostat?

Most thermostats are designed to be compatible with each other, so you should be able to replace your old thermostat with a new one of the same brand without any issues.
