  • Works great
Color: Black Size: 34MM
Exactly what I needed good quality only thing I didn’t use were the worm clamps that come with it those aren’t the best quality but the part itself is perfect.

  • Quoted OD is for the bulb at end of pipe not pipe.
Color: Black Size: 32MM
The quality of part is excellent. Note quoted OD is for the bulb at the end of the pipe not the pipe itself. despite what Amazon says a 32mm does not fit my 4L Jeep TJ, I require a 34mm. Also, to use this part I need to find a 1/4 NPT temp sensor compatible with my Jeep. Wish it was offered with a 3/8 NPT or 1/2 NPT or another size that fits more common temp sensors. ... show more

  • Manufacturer needs to make a 42mm option with a 3/8 NPT sensor bung.
Color: Red Size: 40MM
Made of good quality aluminum with a nice paint job. But the sensor bung is too small for most common applications. I drilled mine out and retapped the hole for a 3/8 sensor. It worked for a couple days but the bolt hole for the ground wire was too close to the sensor hole and developed a leak. I am purchasing another one to attempt again. This time I'll shift the hole away from the grounding bolt hole. It would be nice if they offered a 42mm option since it was a little small for my LS project. ... show more

  • A note on selecting size
Color: Black Size: 34MM
My opinion and experience with size selection (review at the end): You want a snug fit (a little resistance when attaching the hose). Measure the inside diameter of the section of the hose you will be splicing it into. If that isn't an option because you'd have to cut the hose and you can't have your car down for a couple of days, then measure the outside diameter and subtract the thickness of the hose wall X2. Based on the measured inside diameter of the hose, select the adapter that is the next size up (+2mm). You may be able to get away without going slightly up in size, but the clamps will really have to bring it down and while it might not leak, the seal wouldn't be the best. USE YOUR OWN DISCRETION this is my personal recommendation based on my experience: The ID of my radiator hose was approximately 31.7mm and at the very least you should round that number up, so I ordered a 32mm adapter. Upon fitting it, it was appropriately sized, but it wasn't a snug fit and without clamps it would easily fall out. I was concerned about the seal because of how much you would have to tighten the clamps. I decided to order a 34mm and it worked out great. I could have easily used 36mm as well, but since my radiator hose was not new I left room to take into account that my old hose was probably expanded slightly. Great time to just replace the whole hose! Even though you may have to cut it depending on your application. Installation Review: Installation was easy. You will need to make a small grounding wire to attach from the small screw on the adapter to somewhere on the car frame or engine. If you have them, you may want to use hose clamps that are a little beefier than the clamps provided. I used this with an aftermarket Bosch water temp sensor and gauge, using Teflon tape on the sensor threads before installing it into the adapter. I cut out a small section of the upper radiator hose (hot side, using razor blade) to install the adapter. I would install it as close to the engine water outlet as you can. After installation be sure that none of the modified hose sits above the top of the radiator in order to help keep air from getting trapped in the system. One month after install: Everything is perfect. Great product. ... show more

  • Fit my 5.3 upper radiator hose pretty good.
Color: Red Size: 32MM
I definitely could've gone up to the 42mm but this one worked fine. Replace the hose clamps immediately for piece of mind. I also had to drill and tap one side for 3/8npt as thats what my temp sender was threaded in. Used the 1/8th npt port as a bleeder for the cooling system.

  • You get what I pay for
Color: Blue Size: 38MM
I have an 1 1/2" radiator hose and should've gotten a 40mm instead of a 38mm. My fault entirely. Only gripe I had was the sensor hole is tiny. Not a big deal, just drilled and tapped a bigger sizes hole and voila. It's aluminum so it was easy to do. Just sucked to have to do it in the first place ya know ... show more
