this hose is composed of rubber and metal and weird compression fittings, its leaking where the hose comes out of the water pump then to a large peice of pipe, i beleive called a restrictor, its leaking from one of those fittings, what can i do? can i just replace the rubber part of the hose?

 

no if the heater hose is leaking on a performed manufactured part like on our cars you will have to completely replace the whole hose assembly.

 

i took a dremel tool and cut off those crimp on fittings that connected the rubber hose in the heater core valve and replaced the rubber hose and used 2 hose clamps to put it back on, works good so far, no leaks @ all
