In this video I show you how to replace the thermostat in your Ford, Mercury, or Lincoln 4.6L or 5.4L V8 2V engine vehicle. I believe the process is identical for the 6.8L Triton V10 engine and probably some other Ford and other manufacturer engines.

If you find your engine is not getting up to temperature soon enough (slow warmup) or you are having issues not getting enough heat in the cab of your truck, you might need a new thermostat. This is one of the easier DIY repairs that you can do. In my case, I changed the thermostat for preventative maintenance, mine had not yet failed.
In this case I am showing the procedure on a 2003 Ford F-150 but it should apply to 1997-2003 F150s plus other models and 2004 newer F150s with the 4.6L V8 engine. You will need 10mm and 8mm sockets and ratchet to remove the housing and trims under the hood. You will also need a 19mm wrench to loosen the rad drain screw to drain some of the antifreeze or you will have a mess.
Check out my other videos on this 2003 Ford F150, other videos include steering wheel replacement, King Ranch leather seat cleaning, starter battery cable replacement, and more.
The products shown in the video include the Ford Motorcraft RT-1234 thermostat, RG-571 O-ring gasket, VC-1 cooling system flush chemical, VC-7-B gold coolant, and the U-View 550000 Airlift cooling system tool. Thanks for watching. As an Amazon Associate I earn from qualifying purchases.

What is the original thermostat rating. I bought a car quest one today and it never opened, Truck over heated and not sure why, It was rated at 195

@InternetDude 2 жыл бұрын

192. I think you got a bad thermostat, or you have a different problem like a blocked radiator. The thermostat is a critical item so I prefer to stick with OEM parts for critical things like this.

@@InternetDude Kool! Still a beautiful car. Recently saw the door handle module and how it worked. Amazing isn't it that something most drivers never think about, Tesla turns door handles into design fiasco. I'm in the first week with my long range and am still blown away by the car itself and my reaction to it. I can't seem to stay away from it. Got FSD for a 3 month trial and I'm using it fully. Definitely not worth 10 grand considering I have standard autopilot pretty much doing the same thing but nice to try. I'm trying to stay open-minded about it and think of its future usefulness to me and essentially just follow its development directly by buying. I can afford it but would like to know what you think about it, price and usefulness. Yourself along with a few other reviewers had a lot to do with my not buying for a full year. I'm kinda glad I waited cause I believe I got a better car for the wait. So, thx again! Driving position, although comfortable, is not perfect. My long legs have made contact with the screen corner. Would love to move that screen about an 1 inch further right.

The problem with waiting to buy a Tesla is there will always be a better one out in a year. For example by the end of 2021 we will have the new 4680 battery cells.

Any increase in MPG by chance? I’ve just recently seen bad thermostats, Aftermarket can cause horrible MPG and that’s what I’m experiencing will be getting motorcraft thermostat for my 4.6 I just recently put OEM plugs and Coils in mine still getting bad mileage definitely believe it’s the Duralast thermostat I put in

@InternetDude Жыл бұрын

My old thermostat wasn't bad so MPG didn't change. I did it more for maintenance reasons. Scan for diagnostic codes to see if there is some other reason that might be causing low MPG.

I've had three thermostats go bad in The last 5 years. Go bad as in did not reach the correct operating temperature i e they leaked / stuck open a little bit or something. 2 were motorcraft and one was Stant. One of the motorcraft was bad from new it never got above 165F when brand new. After a thousand to 1500 miles I actually got a code for engine not reaching 170 f to complete the emissions drive cycle. The others ended up never getting above about 180 to 185 in normal operation after a year or two instead of the 192 they did originally. And I checked the operation with the scanner after I first put them in. The bottom line is check your thermostats frequently by monitoring the ECT with a scanner. They are ALL junk today. Even the premium ones.

Never introduced tapwater to the cooling system. Contaminants in the tapwater will contaminate the cooling system. Only introduced distilled water and recommended coolant to the coolant system to avoid contamination. If you introduced tapwater or anything other than distilled water and recommended coolant do you wanna introduce contaminants into the system that you will never be able to remove. So don’t do it lol

Distilled water pulls electrons from the aluminum to ionize itself doing just as much if not more damage. You should actually be using softened water.

@@Meanbirds Softened water is not purified water. Softened water will still have contaminants in it they can clog up small offices in the system. Distilled water will not Harm the aluminum once it is mixed and saturated with the coolant. Once saturated it loses his ability to pull anything as it is saturated.
