Review: Works good on my 2001 4.0L explorer - One thing I ran into on the explorer 4.0 is that there's a couple different manifolds. Mine is a 2001 XLT 4.0 built on 9/2001. Everything seemed to line up perfectly. I had to fight the three bolts to get my old one off. One big problem. I did have that I kind of set myself up for. I put the OEM thermostat in. Trust me, spend the extra 15 bucks and get a good quality thermostat. I also tried to put an OEM o-ring on the thermostat. THIS UNIT USES A BIGGER O-RING than the OEM thermostat one. The OEM one will just leak on you. Asked me how I know. So I put the o-ring it came with back in and it works. Also keep in mind to smaller hoses that connect to this but most likely have to be replaced as well. In my case I also had to split the top half of the manifold so you'll need gaskets for the manifold. You can see in the pictures I have the long tube runner manifold style. I've seen the other 4.0 with the skinnier manifold. Sometimes you can slip this thing right out. Unfortunately mine I could not. And I had to take off my top half of the manifold. I was left in a pinch because I did not have the lower hose and my old one was about to blow out. I didn't realize how bad it was till after I got it off. Do not buy the POS dorman replacement hose only lasts about 6 months from all the reviews. The gates one wasn't really for this. It was a 16th smaller id but the outer diameter was larger. It fits extremely close, maybe just a credit cards distance away from that bolt. It's been working for the last 2 weeks in my car. When I find that number I kept it somewhere. The guy at O'Reilly's just looked up for similar items on his computer and when I saw a gates one that was about the right shape asked for that . I just can't find it at the moment. I'll put it up on this review when I do. That way if you're in a pinch like me you're able to get to around. Lastly, I was only able to find one YouTube video on how to take my style manifold apart. It's from like 13 years ago and it wasn't the best quality but it got me through. The only last issue I had was I had to split the lower manifold because those gaskets were leaking on my car. When I split it I realized somehow the insulation on the knock sensor went bad so I had to replace that too. I also found the PCV valve hose to be rotten so keep an eye out for that on yours. Hope this helps. Best of luck to you! It's May 31 2025. I use this car as my daily driver and it's still holding up good.
Review: Well built part - Very well built part. Came with new sensors as well as a new thermostat Comes with bottom rubber o ring too. I put black rv silicone on the bottom around o ring and around top cap for thermostat but hey, that’s just me. No leaks finally. My old part was corroded bad. Puddles of coolant may form directly behind thermostat housing. Soak them up with a small towel before installing new metal housing.
