vindats1 Posted January 6, 2017 Report Share Posted January 6, 2017 hi folks, many years ago I drove to Wallingford, just north of downtown Seattle and repaired (by myself) this older guy's split fuel filler hose on his Datsun, either a 710 or 810 wagon. He was the nicest guy, retired, not much money at all however. Now he says his heater is not working and the mechanic wants loads of money to fix it, not actually knowing the situation. Possibly stuck valve? Or heater core needs taken out and rebuilt? He can pay a bit but not alot. I can give his name and number if anyone might be willing to put on Datsun angel wings and go and give him a call and a visit. His mechanic told him to give up the Datsun but he "really loves" his Datsun wagon and I would hope he could keep it at least a few more years to bring him some happiness. Please write me at: vindats@yahoo.com if you might be able to help him out. I would, but my health as most of you have heard is not so good these days. I still love to play with car parts and sell some parts and take care of my pets, but can't do what I used to be able to do. Feel free to send me an email and just say hello too! Thanks, Tana Bryan home phone: 360 469 4187, living south of Auburn, Wa. 4 Quote Link to comment
banzai510(hainz) Posted January 6, 2017 Report Share Posted January 6, 2017 TELL HIM TO OPEN THE VALVE MANUALY . ITS FREE.. BET A ROD IS LOOSE OR cable NOT OPENING THE VALVE. Had this happen on my 2nd 510. open then heat cam out. On my Z car it was a vacume hose that popped off something. Was weird didnt understand how it worked but that was on the Fuel Injuected 280Z. SELL TO ME FOR 400$ IF NO RUST 1 Quote Link to comment
datzenmike Posted January 6, 2017 Report Share Posted January 6, 2017 Reverse flush with garden hose to remove bar's leak or sediment. Replace thermostat that is stuck open. Car will run better when warm too. Make sure cold air mixing gate is working 2 Quote Link to comment

vindats1 Posted January 13, 2017 Author Report Share Posted January 13, 2017 hi folks, this old guy is not mechanical at all, so he won't be able to figure these possible solutions out. 1 Quote Link to comment
banzai510(hainz) Posted January 13, 2017 Report Share Posted January 13, 2017 Bus ticket if he lived closer I would least look at it. But the newer models are abit more intense on how to get at the valve or vaccum assited valves Arches Father Scott (oldJapanese guy)could maybe look at it if he drives it to his shop Close to GeorgeTown. You know Archie he works at Autosport Seattle. He know you from the NWDE meetings. Now heres the info and if hes motivated to get it fixed he will use this info. Otherwise he better learn ofr take the bus. and sell that wagon Scott(Kato) did my Kingpins cheap. 60$ a side 2 Quote Link to comment
Trophy24 Posted January 15, 2017 Report Share Posted January 15, 2017 Herb came by today so I could pull out his heater box. Looks like the valve is leaking at least. Will see what I can do this coming week 12 Quote Link to comment

KoHeartsGPA Posted January 16, 2017 Report Share Posted January 16, 2017 I purchased a heater valve on ebay last month for $12 new....problem...i haven't received it yet....4 weeks and counting...maybe one of the local guys has one, start with #FuckingTed (tdaaj) he's usually got what you might need. 1 Quote Link to comment
Trophy24 Posted January 16, 2017 Report Share Posted January 16, 2017 I pulled the heater box out so he can still drive it. will pressure test the core and valve tonight and see what is up 4 Quote Link to comment
Trophy24 Posted January 17, 2017 Report Share Posted January 17, 2017 So he had the heater bypassed on a road trip so he could make it home. I had to come up with a way to leak test the heater assembly. Here is what I pulled out Looking it over, I think I see a problem at the heater valve. A pretty common failure point from what I read. I scrounged around in the garage and came up with a tool to pressurize the system. Not the pretty example you would buy on the tool truck, but it should work. The hoses are pretty long, but I didn't want to cut them just for this adventure. Have to be super careful with this sort of thing. Twist the regulator valve too far and there will be some serious damage here. I practiced to get a feel for the regulator before connecting Looks like one of the hoses is leaking. Aaand the valve too. Good news is the core appears solid I'm going to try the NAPA o ring rebuild method I found searching ratsun. Will stop on the way home tomorrow 4 Quote Link to comment
KoHeartsGPA Posted January 17, 2017 Report Share Posted January 17, 2017 I tried the o ring thing, mine was so worn it didnt work, thats why i ordered a new one....still waiting for it.... Quote Link to comment
Laecaon Posted January 17, 2017 Report Share Posted January 17, 2017 O ring worked great on my 510. While you have it out, Pour some CLR into the core and let it sit. Then (with valve out of circuit) connect a garden hose to the core, switch back and forth on the inlet/outlet. I blasted out tons of corrosion from my core doing this. Made my heater work awesome when it didnt before. 2 Quote Link to comment
banzai510(hainz) Posted January 17, 2017 Report Share Posted January 17, 2017 looked like a MOFO to get out 1 Quote Link to comment
]2eDeYe Posted January 17, 2017 Report Share Posted January 17, 2017 It's getting harder and harder to get those valves. Maybe something from another vehicle would work? Quote Link to comment
carterb Posted January 17, 2017 Report Share Posted January 17, 2017 You are a very kind man Paul! Thanks for helping the ol' guy out. --carter 2 Quote Link to comment
Trophy24 Posted January 18, 2017 Report Share Posted January 18, 2017 Hey thanks guys. Seemed like the thing to do to help him out. The heater box came right out pretty easily. The heater hoses were already disconnected. 3 bolts, 2 cables. Pull out the ashtray, shift into 4th and out it came. Looks like a new valve is needed. The 4 prongs were pretty rotten. Very careful hose removal broke the retaining tabs. Boo! Quote Link to comment
q-tip Posted January 18, 2017 Report Share Posted January 18, 2017 Yeah, that valve has had it. Quote Link to comment
Trophy24 Posted January 18, 2017 Report Share Posted January 18, 2017 Think I found a solution. It will require some modification. Looks remarkably similar. I think I can figure out the mounting bracket pretty easily 6 Quote Link to comment
