Ford Focus coolant leak heater core pipe leaks coolant on carpet orings tips

G'day guys with only a revised heater core with fixed pipes available in Australia for $575 and all the associated labour to replace the entire unit located in centre of dashboard we have repaired this particular car with orings. The lower hose is a lot firmer in position and after making this video had to replace the orings several times to arrest the leaks. The car has run for hours been road tested carpet dried and returned to customer. Make sure to lubricate orings and use narrow orings. Make sure to confidently install the pipes in one firm action as they are exactly lined up. Refill with water to test. Do not dought yourself and jiggle hoses. Of print pinched or misinstalled simply repeat the procedure until you get it right. O. This vehicle the upper pipe o-ring was disintegrated whilst lower was actually ok. So it it's top one leaking do yourself a favour and replace only the top one. As it seems bottom one is under less stress and heat.
