This one is supposed to be easy, it is not, you may have to do more hose cutting than you want...

mine is a molded hose. This will not work on my truck. Seller wants me to ship it back, shipping cost the same as device. Now useless to me. Sitting on shelf in garage since last summer.

Very simple to use for flushing the coolant from your vehicle’s system. It can be left in place for possible future use.

I use 2 sets to isolate heater for flushing. I don't lose all my coolant just to flush a 20 year old heater core.
