Maples71240Z

I have a extra one from my 71, sent you a PM Dave

I just saw this and know nothing about it or who owned the stuff Craigslist in Portland Oregon, http://portland.craigslist.org/clc/pts/3369530703.html

It's quiet and about $6.50 a foot I have used it for years on the shop equipment. But the stuff is fractional HP belt and has a different pitch than automotive belt. If you are going to try it get the 3L (3/8") Dave.

I have about 6 of the Ford inertia switches with wire pig tail. If you wnnt one for $8.00 shipped just PM me Dave..

Moved to the correct forum

The 280Z radiator will bolt right in, but it is taller and the lower tank hangs below the radiator core support. It would be easy to damage/puncture the radiator lower tank. Be safe and use the 240Z radiator. Dave.

I have made up a bunch of the Z battery cables using welding cable and crimped ends with a clear shrink tubing so I could tell the condition of the crimp connections. I use a coating on the crimped end called Ox- Gard that is a anti-oxidant compound (not dielectric compound/grease) The best place to buy the ends that are as close to correct as one can find is Genuinedealz.com or their Ebay user name: Genuinedealz. These guys have free shipping and the quality is great. Dave.

Called a residual pressure check valve, Nissan does call it a proportioning valve in everything I have seen. But it as you said is not a proportioning valve. Dave.

Chevette? I think a Vega would be better 8^) Dave.

I bought a Blazer new in 1978 and used WD40 as a cleaner and protectant from day-1. To this day the dash is still perfect and this vehicle has never been parked inside. I have never seen a un-cracked dash in one of these old Blazer/GMC trucks or pickups. It's too late for my 240Z because the dash cracked years before I got it. Dave.

That is true with my JIMMI since it has been a while since it had a coolant change and now the reading is .14 Volts. But the Z was changed a couple months ago and it reads .57 Volts and that reading drops when the battery is disconnected.

I am not really new to working on cars since I have over 45 years of working on cars under my belt. Many years ago I used a volt meter to test antifreeze but for some reason I stopped and never used the test again. Below is some info I grabbed off Google about it. What I am looking for are some test results from you guys on your Z's and whatever else you have to test. I tested a S15 JIMMI I have and it was high as was my 71Z. I think my Z has a ground issue that is causing the high reading. The JIMMI was dead antifreeze but the high reading is what I think caused a freeze plug to leak and the steel back plate of the water pump to leak. This weekend I will tackle the Z to see what is causing the high reading. Checking antifreeze with a volt meter Googled this and found its a great test procedure. Bad grounds can cause the readings below, as well as dead anti rust/corrosion inhibitors. once the readings go high all kinds of nasty things happen. Electrolysis of the radiator. soft plugs to name a few. What is Electrolysis? As the additives in your coolant that keep it neutralized become depleted the coolant actually develops an electric charge from passing over dissimilar metals. You can even measure this voltage with a voltmeter! This small electric current removes metal from engine surfaces leaving large pits or holes and can eventually eat entirely through a component. It can also weld bolts and fittings to the engine and components. The American Society for Testing and Materials (ASTM) did testing with hydrometers and deemed that the majority of hydrometers are inaccurate. as a result of this, they removed hydrometers from the approved methods list for testing coolant. stray current testing is a good indicator Then there is PH testing with the`test strips. Just Google antifreeze PH testing and see for yourself. It does look interesting These are the common readings off the web Negative digital volt meter lead to battery negative, positive in radiator cap touching only coolant. 0.2 V to 0.5 V - antifreeze is still good 0.5 V to 0.7 V - antifreeze is borderline 0.7 V or greater - antifreeze is unacceptable.

I have the piece here that your looking for but the nut is frozen in the wheel cylinder. I am just across the river from ya and you can have the backing plate complete if you want it. just PM me. Dave

Just go to your local parts store and get a BLJ-320 brake line and bend it to fit. That is going to be the correct tube and nut size for your Z. Only thing needed to bend it is a pair of gloves. Gloves help a lot when bending brake lines. This is all I did to replace them on my 71 that happens to be the same as yours. Easy job to do. Dave...
