4runner 3.0 heater hose kit
Bought a silicone heater hose kit for my 92 4runner with a 3.0. Two of the hoses supplied were not the right length. The main connecting the valve, passenger heating, and coolant from engine was too long and overshot the engine fitting, trimming it down and adding a 45 degree fitting. Also the line coming from the heater core to the engine return is much to tall, still worked but looks dorky. Rest fit fine.
I'm sorry you had trouble with your kit. Did you have a chance to reach out to our or HPS, the manufacturer's, customer service to diagnose the problem? There's a good chance you car is the one that's listed as NOT fitting in the product description.
