Muzzys HEATER CORE BYPASS KIT, Universal, Fits MOST Vehicles and ALL 5/8" and 3/4" ID Heater Hoses. Easily Stop Flow to Your Heater Core With This Premium Hi Temp Hi Pressure By-Pass Kit. Made In USA!

This mad a huge improvement in the cooling of my AC on my Ram. Well worth the investment

It fits a 5/8 hose just fine. Anyone spliting hoses installing has old hoses that need to be replaced.

I literally installed this in 3 minutes one morning as I was rushing off for an appointment. It did exactly what I needed it to do 1.) Restore air conditioning effectiveness. 2.) Perform with an absolute minimum of effort and bother. 3.) Hold the promise of continued service into the indefinite future. Score!

Very good selection of parts. As if you would have gone to the hardware store and picked em yourself. Daves you time and gas of getting these, may be worth most added expense.

nice looking, but doesn't fit a 5/8" heater hose. Mechanic said it could be forced on with some lubricant but this weakens a heater hose. With car running such high temperatures that is a risky proposition. Seller should amend description that it's for a 3/4" . I should have wondered about the 'universal nature of this- my mechanic said a smaller OD could be wrapped with correct tape to fit into the 3/4 hose ID, but not vice versa!

it does not fit 5/8" heater hose it rips apart the inside of the hose when you try to install it

The handle and valve are really loose. Can actually turn on its own from vibration.

fit and finish was nice. clamps were decent quality

I installed this on my ram 1500 5th gen and finally I have ice cold air conditioning. This is the fix you need for the ac in summer. No idea why these trucks pump heat in to the heater core all the time when set on cold with the ac on. This shuts off the heat to the heater core and my ac is finally cold. Working out in the heat everyday in construction and this thing Is a God send when you can get in your truck and the ac is ice cold

جيد جدآ ونافع بس سعره شوي غالي
