HumanoidThe23rd Posted September 16, 2011 Report Share Posted September 16, 2011 Hey guys. So a buddy of mine and I have been rebuilding my 720. We are almost done! But we need some help. We need to know the heater hose routing, vacuum hose routing, and the wiring of the alternator, and wiring for a few other simple things. If someone could get back to me with some information that would be great. But would be even better than that would be a couple of pictures of the things I am talking about. I would be insanely grateful. This project has taken way too long and I've got a few more waiting to get started.. including dropping a four speed in my 70' 510! Please if someone could help that would be great. Thanks Guys. Long Live Ratsun! Quote Link to comment
datzenmike Posted September 16, 2011 Report Share Posted September 16, 2011 If it helps the direction of flow through the heater doesn't matter. There is no left or right heat. Quote Link to comment

HumanoidThe23rd Posted September 17, 2011 Author Report Share Posted September 17, 2011 Thanks for the help so far. But can anyone else help us? Quote Link to comment
poopypants720 Posted September 19, 2011 Report Share Posted September 19, 2011 Ill take some pics of a manual for you.... But you realize absolutely everything is available in a haynes manual that your asking about? Its worth 20-30 bucks to just go get one for future reference and repairs as well...

HumanoidThe23rd Posted September 20, 2011 Author Report Share Posted September 20, 2011 I have one. I guess I should thumb through it a little more. I've looked through it a bit with no success. Quote Link to comment
Sealik Posted September 20, 2011 Report Share Posted September 20, 2011 I have one. I guess I should thumb through it a little more. I've looked through it a bit with no success. Did you try those links I provided for the vacuum line issues? Quote Link to comment
HumanoidThe23rd Posted September 20, 2011 Author Report Share Posted September 20, 2011 Yes those will be very helpful for sure. I've looked in my manual and it was no help. What I need to know or see, is where the two heater hoses come out of the firewall, where they go. There is little to nothing about the heater in my manual. It just talks about removing and installing the heater assembly, as well as the heater core. If someone could please explain where those hoses go or let a picture do the talking that would be great. Thanks Guys Quote Link to comment
datzenmike Posted September 20, 2011 Report Share Posted September 20, 2011 Water comes out of the right hand side of the block at the very back below the rearmost intake runner and above the starter. The return hose from the heater is close to this one, and is connected to a fitting on the underside of the intake directly below the carb. Here it mixes with warming water from the intake runners and is piped forward to the lower rad return hose and back into the pump. How's that? Haynes/Chiltons are crap for stuff like this. Spend $40 and get a Nissan factory service manual FSM for your year. Quote Link to comment
Sealik Posted September 20, 2011 Report Share Posted September 20, 2011 Comes out the side of the block into the heater core (bottom hose at firewall which actually have arrows on them denoting flow), out of the heater core...tees off into the bottom of the IM and proceeds to the TC cover/water pump Quote Link to comment

HumanoidThe23rd Posted September 20, 2011 Author Report Share Posted September 20, 2011 Thank you guys for all the help. This is why I love Ratsun. Everything from fenders to simple questions like this one. But I honestly think that whats going to help us the most are a few pictures of an engine bay, of the heater hose routing etc. If someone could please take a few pictures I would be insanely grateful. Either way though guys. Thanks Quote Link to comment
