I can't be certain that my '70 car never had this part, but I have owned it since 1978 and I did not remove it. To me it seems strange that the manifold heat control thermostat is not mentioned in the 1970 FSM. Also in looking at the parts manual I noticed the pipe manifold that wraps around the back of the engine connected to the hose that connects to the thermostat did change in 09/71 (item 26 on the attached parts book page). On my car the thermostat would not physically fit unless I bent or modified that pipe manifold. I could be wrong but I think the fact that there was no start date in the parts book for the thermostat might indicate it could be backwards compatible if you also change to the newer pipe manifold (p/n 14053-E8800). Just some food for thought. Mike Edit> I missed answering your question about "no-thermostat solution and blocking off the circuit etc." Your logic does seem to make sense, all I can add is that over 38 years of driving my car and not having this thermostat with the coolant path open I have not had any issues. Maybe others with original series one cars will jump in and offer opinions or confirm if this part was in fact originally included on their car. I wonder if anyone has an old parts book from 1970, mine is from 1978. To me it looks a little ambiguous that the item 38 thermostat is offset and parallel to the pipe string and why would item 20 (connector-water) be required when the thermostat case cover can thread directly into the intake manifold? Just curious.

Lot's of good info here, thanks for sharing this. Was the manifold thermostat first installed on the 1972 model year as that's what it seems to state on page EC-12 of the 1972 FSM. I don't have one on my 1970, and I don't believe there ever was one, also I can't find any mention of it in the 1970 FSM. I see the benefit of having this thermostat, I'm just curious about when it was introduced.

I remember seeing this TSB a while back and I thought it was relevant to this thread: Does anyone have these clips? The dealer was supposed to install them during PDI. Mike

Interesting that you mention using Solid Edge, that's the main cad modeling program I use. It was motorman7 that was working on the engine model, in Solidworks I believe. He did some very nice work. The main problem with the free cad models available on the web is that they are generally surface models with no inner detail, and they can be quite difficult to convert to solids. It would be great to see a collaborative effort on our site to create and share both 2D & 3D cad work related to the S30, maybe we should add a section in the downloads area for this. Mike

Here's a link to a surface model of a 240Z that I found on GrabCad, It's a little rough but not a bad first effort for a student. The person that created it used an educational version of Solidworks, but I was able to open it with the full version. https://grabcad.com/library/240z-model-1

I think this is what you are referring to: http://www.classiczcars.com/topic/43715-s30-in-3d/ Good luck Mike

I'm pretty sure "op" does mean optional, here's another example of "op" in the parts book for wheel selection.

Here's a parts book page showing an optional one called "KNOB-CONTROL LEVER SKIN" PN C2885-E4600, the others shown say wood.

I agree that setting the gap to be loosely touching is best. I noticed that if the gap between the bumper and the cross member was set to 4mm on my car then it would not help in the unlikely chance that the rack rotated. On my car the gap between the pinion gear housing, at the face where the pinion shaft exits, and the cross member is less than 3mm, so that would hit before the bumper did. See the area pointed to by the red arrow in this picture.

Mine almost touches the cross member, I can just get a .010" feeler gauge in between

I just found this TSB regarding the cowl top panel support issue, it was implemented in Mar. '71. The complete 1969 to 1972 TSB document can be found in our downloads section. Strangely it's in the manuals folder, not the service bulletin folder. Mike

Here is a good discussion regarding the steering rack bumper/bracket clamp, likely was not factory installed on your early car. My 7/70 car does have one, no idea if it was factory or dealer installed. Strangely I couldn't find any mention of it in either my 1970 or 1972 FSM. http://www.classiczcars.com/topic/48076-rack-and-pinion-u-bolt-clamp-71z/?hl=%2Bsteering+%2Brack+%2Bbumper#entry437353

This thread has been an interesting read, here's one from the dash of my 12/70 parts car.

I am, and have been, using IE11 as my browser and have also noticed the loss of the expandable side menu on the left as you mentioned. It was definitely better with that feature IMO. There was a good Microfiche page for S30's on xenonzcar.com but it is still not working, here's the link to the ref page, it's part way down after the FSM's: http://www.xenonzcar.com/s30/reference.html Maybe they will get the microfiche page working soon, most of the other links are working. I'm not seeing the "?" mark problem.

I suspected that it was not exactly what you were looking for, but there is a lot of good info there. I think that L20A/L24 engine manual was for 1970 as the 240Z FSM for the first year was only available as a two volume set with neither the engine or body/chassis book having the year on the front cover. The early FSM books did have an issue date on the back cover. Good luck on your search.

Not a C211, but here is a link to a site that has a C210 FSM: http://datsun510.com/manuals/ My Skyline knowledge is very limited so I don't know if this will be of any help. Mike

You got me looking at the seals in this area on my car and I noticed one other small seal, on the lower forward corner of the quarter windows. When the door is closed it will virtually mate with the small seal on the door just mentioned above. I'm missing the one on the LH side, here's a couple of pictures and a parts book image: MSA has these: http://www.thezstore.com/page/TZS/PROD/classic03a09/34-1014 http://www.thezstore.com/page/TZS/PROD/classic03a09/34-1015 HTH Mike

I think this is the other seal Jim is referring to: http://www.classiczcars.com/topic/46661-upper-corner-door-seal-picture-please/ I believe it's items 9 & 10 here:

These two links should answer your question: http://www.carpartsmanual.com/datsun/Z-1969-1978/body-240z/door-moulding-finish-arm-rest http://www.carpartsmanual.com/datsun/Z-1969-1978/body-240z/body-side-trim-side-window HTH Mike

I guess it's presented as a model evolution, plus anniversary cars. Hard to include all of our great cars in a 24" x 36" format and still have a high level of detail. I like the quality of the artwork which was done by well known automotive artist Gavin Macleod, who passed away in 2003. He is remembered for his Formula 1 and other motorsport works. http://www.gavinmacleodcollection.com/artist-biography/index.html Mike

Under dash to the right of the steering wheel. See item 17 on this picture from the owners manual. This is from a 1970 but I think the '72 is in the same place. HTH Mike

Hey Dan, my decal is still the original, my car is unrestored under the hood. I checked out your thread on this subject http://www.classiczcars.com/topic/19815-interest-in-master-vac-decal-reproduction/ and I noticed that my label is actually a little different, it doesn't include the patent number and the format is a little different, otherwise very similar. Here's mine: Mike ps: Sorry to Ken for the hi-jack

While looking thru some old drawings for a project I am working on I found this cool poster. I don't even remember where it came from.

Dan, I think your description of the "grill cowl top" support is correct. Here are a couple of pics showing this (I did an inspection of this area earlier this year). The foam pads on mine are about 3/16" to 1/4" thick and the material is relatively soft. Mike

Looks you are still missing a digit in the SN, are you sure it's not 400249? I think 40249 would put you in the range of a '71 240Z. All the same very nice car.
