Update: Block heater is installed. The PO had one of those expandable plugs in there, so taking it out was actually relatively easy. Just a couple turns and a needle nose pliers, without having to remove the manifold or anything. The heater went in a little tight, but overall it was a fairly easy install. I'll throw some pictures and a part number up later.

Well, 40mm is what it says it should be!

I will take a look a little later today.

Did you get around to it?

Does anyone have a Z24 out of their truck and could measure the diameter of the left rear freeze plug? I'm looking at this block heater. Amazon says it fits, but obviously doesn't tell me which freeze plug it would fit in. I say the left rear because that is the one on my truck that is having some leaking issues, and if I can replace that one with a block heater, it would kill two birds with one stone. If you happen to have the freeze plug off, I would also like to know the depth from the edge of the hole to the cylinder wall, because it would suck if the element was too long.

I think the 2nd one is the easier install but you bring up a good point of the radiator.... I would think the one in the freeze plug would be better since it heats the coolant in the block first before the heat eventually gets out to the radiator...

My thoughts exactly. What's the point of heating coolant outside if the thermostat would be closed and not preventing flow? I do not think it would help with cold starts either.

Just a fun update: It was -15 degrees fahrenheit in Minnesota this morning, and I had to get home from a friends house. I do not think this truck has ever seen temperatures this cold in it's life (Cali truck), and it sure was not happy about it, but it did start without too much issue. Couple of pumps, turned the key and after a few wubs it started up. My biggest concern was actually the transmission oil because the transmission lever was very stiff as well as the clutch. After letting the oil warm up I took it very gently and just kept it in fourth gear the whole way home. The variety of conditions that this truck can handle considering its age amazes me. A question for the Canadians on the forum: Do any of you run those stick on oil pan heaters to keep the engine oil warm? I've been thinking about picking one up because as fun as it is to drive in these conditions, I know it's hard on engine components when the oil is that cold.

I made a valve lash video for the 720s and put it on the You Tube.


Hope I did it right.  :rofl:



Watched the video; Nice job! See you keep that FSM on your phone!  :thumbup:

Nice! Jealous of the studded tires. MNDOT doesn't allow them on public roads, but my Arctics are studdable in case I want to drive up a mountain. Oh wait... I have no mountains.  :crying:

Now all you need is some snow tires and your truck will get through everything. I got new General Arctics last winter and I never had to engage the 4x4. It's amazing what a *relatively* light truck will go through that a heavier truck will struggle with.

Nope, I have literally driven it about 1/8 mile with new radiator and it is around 19°F out there. No overheating issues whatsoever. I was just thinking about when it will be 100°F this summer. I was just doing some research and the internet told me they were an absololute necessity. :)

If you sit in traffic on a humid 90 degree day with the AC on, then you might run into a heat issue, but I did not have that issue with mine.

Ok so I guess fan shrouds aren't just there to keep our fingers safe? I have been considering making one out of fiberglass, maybe make it easy to remove. Has anyone here tried this?

I had the same issue when I put a new radiator in; not having the radiator shroud in there as been better for me personally, but I agree that it helps with airflow across the radiator. Are you having overheating issues?

#1535492 1985 720 4x4 blue relay ticking question

Posted by MaxChlan on 19 December 2017 - 02:50 PM

I tried to do some digging on when the clutch safety switch was mandated, and I could not seem to find a solid answer. I even tried to go through the Federal Register and nothing was popping up except for an amendment in 2005, but I can not trace back to the original document it was amending. My theory is that there is no such law mandating them, but every automaker installs them to prevent such a ruling. My 86 doesn't have one, but I would like to place small wager that when Nissan went to the D21 in 1986.5, they installed a clutch safety switch. I wasn't alive then so I couldn't tell ya  :rofl:

So much great stuff in here. Here's what I am thinking: When I get home, I will adjust the pedal play, take a second look at the master cylinder level and make sure we have enough fluid; this should hopefully fix my reverse issue (based on what Mike and Wayno have said, it seems to be that the clutch just isn't quite disengaging all the way).The transmission doesn't make any of the stated growling or whining noises, but when it does, it will most likely be the front countershaft bearing, which in my B series is 62 mm because it is a later one. Does anyone have a source for bearings for the B transmission? It seems as though every transmission rebuild website I go to thinks that my truck has a 71C transmission.

The clutch was changed at around... ah, I don't have my book of records on me but I want to say that it was changed at 135,000, and there are a little over 141,000 miles on the truck. When we changed the clutch we changed the transmission oil, and I believe we used Redline 50305 MT-90 75W90 GL-4 (according to my Amazon account). After we changed the clutch we put a new master and slave in, bleed it properly, ect... I may have to adjust the pedal play because I like the clutch to operate right at the bottom of the pedal actuation so I do not have to move my foot so much; maybe that is what is causing the issue. When I get back to the US I will double check all of the fluids (even though I do it every time I fill up for gas).
