sam Posted February 27, 2012 Share Posted February 27, 2012 hello there I was wondering if someone may be able to help with a few things. As off last weekend I discovered that my heater hose pipe has a hole in it at the very end where the hose goes on it. The end that is under the intake manifold. Coolant leaks out and the engine starts to over heat. its a 5m-e 2.8l in my mx73. I want to try bypass the heater core but i am unsure how i would go by doing so . The heater hose pipe is also connected to the water pump. I Would need to bypass the whole beginning of the heater hose, theres also another hose that comes onto the beginning of the heater pipe i would need to bypass aswell. Could i just run some T joints and a hose to where the pipe comes out of the fire wall and splice into the hose and a T joint there? Any help is appreciated !

Shandangles Posted February 27, 2012 Share Posted February 27, 2012 there will be a hose from the engine to the heater core (hot side), and 1 from the heater core to the engine (cold side) you need to loop from where the hot side leaves the enhine to where the cold side returns to the engine. in saying that, its an "M" series so is prob overheating cuz the head gasket is fucked Quote Link to comment Share on other sites More sharing options...

durty Posted February 27, 2012 Share Posted February 27, 2012 if you know where its leaking why would you bypass it? either replace the hose or if its near enough the end then chop it off where the hole is and stretch it to the connection Quote Link to comment Share on other sites More sharing options...

fulloc Posted February 28, 2012 Share Posted February 28, 2012 is it the rubber or metal pipe thats got a whole in it? you could easily jimmy up a rubber hose to replace the original or bybass the heater in/out hoses see page 24, avail at any part place http://www.partsland.com.au/Catologue_P ... oseWeb.pdf Quote Link to comment Share on other sites More sharing options...
sam Posted February 28, 2012 Author Share Posted February 28, 2012 is it the rubber or metal pipe thats got a whole in it? Its the actual metal pipe the on the end where the rubber hose goes on it is where the hole is located Quote Link to comment Share on other sites More sharing options...
KKtrips Posted February 28, 2012 Share Posted February 28, 2012 Take the metal pipe off and get someone to braze it up - shouldn't cost more than a box of piss. Quote Link to comment Share on other sites More sharing options...
Spencer Posted February 28, 2012 Share Posted February 28, 2012 YEa man up take it appart and fix the problem, even if it is to coroded to braze someone could make one for a fraction of that Japan price. You are asking for trouble if you have driven this thing around in this condition and got it hot Quote Link to comment Share on other sites More sharing options...
sam Posted February 29, 2012 Author Share Posted February 29, 2012 Its a real bitch to take off its right under the intake manifold and loops behind the block, might have to though probly my easilest option cheers for the replys Quote Link to comment Share on other sites More sharing options...
