  • Works great.
Color: Red Size: 38MM
Sizing was a bit snug. Seems well made. Does what it's supposed to. No leaks. Fans turn on and off like they're supposed to. Don't forget that it needs to be grounded separately.

  • 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

  • Manual gauge was needed
Color: Black Size: 40MM
Splice was easy to install. Good quality build lightweight and worth the price. No issues of any kind other than a very vage set of installation instructions. The instructions need to be a little more informative then what they are. The description of the product needs to be revalued and better described. The description needs to point blank state weather it uses a electronic sensor or a manual sensor. Overall a great product ... show more

  • Great product
Color: Black Size: 36MM
I used this to convert my son's 2011 Nissan Frontier from mechanical to electric cooling. It couldn't have been easier to install, and is still working leak free months later. Great product, especially at this price point.

  • Purchased with the intent to modify. worked 100%
Color: Blue Size: 38MM
This worked great although I agree that the millimeter sizing is a little funky when you're trying to go to radiator hose I was able to get it in there and the clamps are tight and it doesn't leak. Additionally I knew that the tapped hole was too small for my sensor so I was banking on there being enough material up top to drill it out for a 3/8 inch pipe tap. Everything worked out nicely and I'm very happy with the quality of the product. I'm considering getting one for the lower radiator hose and putting a drain petcock in it ... show more

  • Be careful turning your fitting into it.
Color: Black Size: 36MM
It is made of softer aluminum and you can strip threads if you aren't careful. Other than that it works great. I used it as a coolant drain and a 2nd one as a distribution for a coolant pressure sensor (never know when a head gasket is going to go) for my turbo BMW E46 325ci. This thing works great, doesn't leak so long as you use coolant-compatible sealant on the threads and properly torque them, and comes with 2 hose clamps. Make sure to tighten the hose clamps with a ratchet and not just a screwdriver- screwdrivers slip and don't put enough torque to hold a coolant hose together under the pressure a cooling system is at while operating. ... show more
