Inspired by the Head cooling on cylinder #5 thread (http://forums.hybridz.org/topic/59029-head-cooling-on-cylinder-5-solutions/), I decided to make my own diagrams of the cooling system for US Z/ZX L6 engines. I had to exaggerate and diminish a few proportions to maintain decent flow while using a flat layout. These charts are as accurate as far as my knowledge and research have shown so far. I will gladly accept any corrections and update accordingly. The year cutoffs are approximate and do not reflect all of the small month-to-month changes of course. On the ZX diagrams, some cars got the throttle body heaters while others didn't. I left them in both diagrams just to cover all the bases. I did spend a fair bit of time on these, so if they do happen to find their way elsewhere on the web, make sure at the very least to cite where they came from. Red = oil passages Blue = water passages and flow direction Yellow = direction of water flow in flexible hoses 1970-1974 240Z / 260Z 1975-1978 280Z 1979-1980 280ZX 1981-1983 280ZX

I spent several days researching ways to improve the air output on my 76 280z and wasn't able to find a really nice walk through, so I thought I'd share what I did. It looks like most of the people who put 1988-1991 Honda Civic blowers in their Z weren't able to feel a big difference. I noticed some people also suggesting using 1993-2004 Kia Sportage blowers. So, off to my junk yard I went. I found both a Civic and Sportage blower. After comparing the two, the Kia blower seemed better built and had a larger cage so I bought it for $30 and proceeded to my Z. The nice thing about this upgrade is that the Kia blower is roughly the same size, it rotates the correct way, it uses the same wire harness, and it uses the same mounting holes. It just so happens that I have taken my dash out to install a dash cap and add LED instrument lights. I don't know if you could do this upgrade with the dash in place because the entire blower housing has to be removed. This is the guide I followed for removing my dash (PITA!) http://www.classiczcars.com/topic/5934-removing-dash-and-interior-for-paint/ Here is the blower housing location The original blower and cage are on the left. The Kia unit is on the right I removed the foam padding from the fan housing since the kia unit doesn't need the extra spacing. Next, I placed the Kia blower cage over the hole, lining up the bolt holes, and marked the area to widen. I highlighted this in red. Using some aviation snips, I cut out the excess metal. I cleaned up the hole with my Dremel later. I then placed the new Kia unit in the blower housing and secured it using the original bolts and washers. The unit spins free and has just enough clearance The original Z wire harness fits right into the new motor. I plugged it in to make sure it works and it really seems to put out some air. I'll post another update once I get the dash back in.

It snowed today in Louisiana and it reminded me that my heat hasn't been working, currently typing with numb fingers. Here's what I know: No heat comes out of any vents no matter what setting. Outside temp air is blowing through the center vents and the side vents no matter the setting. I got the car to operating temp and felt the heater hoses to the firewall, both were hot to the touch. I checked the vacuum lines from the manifold to the heater solenoids and they were connected fine. The line from the solenoids to the firewall is fine too. (Haven't checked inside dash yet.) It's possible that I might've unplugged a vacuum line that runs under the dash to the AC/Heater unit. I've pulled my radio and my center console out plenty of times. Might've snagged something. Since I have hot coolant flowing through the heater core and the hoses I don't think it's a heater core issue. I'm suspecting the climate control panel or something connected to it. It's my understanding that when you switch your climate control to heat/defroster it should immediately pump air through the defrost vents/floor vents. Mine always blows through the center and sides on any setting. Also, My lever that controls the "Hot/Cool" temp of the air coming through feels really bad and not properly set up. Hard to explain but it feels almost spongy and doesn't stay where I put it. I read that it's a cable that controls this and I might have to adjust it. Also possible that the door that controls which air gets blown through the vents is stuck? Could the solenoids that control the heater be seized? I haven't tried checking all of these yet because I'm really not looking forward to pull my dashboard out. I don't have a radio installed right now though so maybe I could access this through that hole? I'm just looking for someone that maybe had issues similar to mine that could provide some insight. I HAVE got my heater to work ONCE before, and I don't know how I did it. It was last winter and it was a seriously cold night and it just worked. I had heat pumping through my defrost vents but nothing since then.

sporadic heater/defrost switch- help
trevormares posted a topic in Trouble Shooting / General Engine
Hey Everyone, My heater blower/defrost switch is working sporadically, and with no rhyme or reason that I can tell. They will work and I can have the car parked, turn it off then immediately on again and then they won't work. Only thought I have is they aren't getting enough power. I think this cuz I've seen the defrost switch light almost go out, but a quick rev brings it back up again. Maybe change the a alternator? Any thoughts? Thanks 71, 240z -
Hi everyone, I'm changing out the heater control valve in my car and possibly the heater core while I'm at it. I want to replace the hoses since there's a good chance that the current ones will crack or break when I remove them. I've been trying to source new ones and I can't seem to find the whole set anywhere. I was going to buy 2 of the 3 at Black Dragon but after checking their diagram and my car's setup, they seem to be different so I'm hesitant on buying from them. Not to mention a lot of them are fairly pricy... I'm not really looking to pay $70 for a few little hoses. Do I need the shaped hose? Or could I use some unshaped hose instead? And if I need the shaped hose, can someone point me to a place that sells them for a reasonable price? EDIT: For clarification, the hoses pictured here are the 3 I'm looking for: Thanks. - Brandon

Got a 78 280z, the air conditioner parts are there, not hooked up together, but all there, however the interior dash control panel does not have an area on the panel to slide to the a/c. I need a different panel for my dash and the guts that go behind it so I can get some a/c in my car, I live in Texas, it's hot. Anybody have one for sale or know where I can purchase? Text me at 325-518-0007. Thanks.

Hi everyone, Recently my uncle has helped me to tackle the issue of my heater not working. Upon taking out the glovebox and center console to get an idea of what's happening (or rather what isn't), we noticed a couple things. - The cable that is actuated by the temperature control seems to be rusty and isn't moving. It's also bent. The one I'm referring to is the one that's behind the passenger side dash, not the one that's connected directly to the switch on the control panel. - The hoses for the inlet and outlet of the heater core should be replaced. I was hoping to replace the heater core while we were at it because i'm almost positive it's original, but the hoses would need to be replaced at the same time. - The heater control valve seems to be pretty worn out and may not be functioning. I'm not entirely sure what this part is actually called or what its specific functions are, but there is some sort of spring mechanism attached to it. My uncle is fairly certain it's some kind of thermostat. It's the part that is shown in this picture: And of course, finding these parts has been nearly impossible. I found hoses for the inlet and outlet of the heater core on ebay, but they're over $20 each. I've only found the heater valve in one place and it's priced at $200 there. As for the temperature linkage, I haven't been able to find anything. I'm not sure if this is because I don't know the proper names or perhaps these parts are just impossible to find. Can anyone help point me in the direction of where to buy these parts? Thanks - Brandon
