late 80's series thermostat (90916-03094)?

[landcruiser3DP]

i'm trying to find a 97 lx 450 thermostat in the fiche. there is another thread that calls out 90916-03117 for this part but i think it must be for an earlier model.

i am finding 90916-03094 in the parts list but but when i go to the fiche it is listing as 16331A.

i guess this is correct but everything else i find in the fiche - well the heater hoses which were a real bitch - had at least some numbers in common.

is this the right part i guess?

is there any reason why this part and the hoses don't have a correspondence between the number on the part in the fiche and the part number in the list of parts?

ALSO - may as well go ahead and ask now (even though it may be in the FSM in the intro somewhere) - but is there some /meaning/ to the prefixes and the suffixes in a part listing?

90916-03094

i did notice that the gaskets seemed to all have the same suffix? or the hoses would have the same suffix or something (like XXXXX-03094 or whatever)? so i guess the suffixes and prefixes have some standardized meaning?

and what was the term again for the syntax they are using? PNS or something? i asked before and i guess i need to search wikipedia for what this standard is exactly. some kind of SAE thing i suppose...?

Part number 90916-03117 is correct for a 97 lx. 90916-03094 is an older part number that is superceded by 90916-03117. The 16331a is a pnc, part number callout and lets us find parts quicker in the epc. Both part numbers are interchangeable with one another so it typically comes down to availability from Toyota or Lexus on the older part numbers.

hey man. thanks a lot. someone was kind enough to straighten me out on PNC as the Parts Number Code. what is EPC please?

also. is there a term for the shortened code? i noticed it often has an appended A, B or C etcetera.

and the longer hyphenated number. is there a term for that? or is there any relation between the prefix before the hyphen and the suffix after the hyphen and the orher 16331A number?

lastly - i did notice that like 06110 or something seems to be gaskets or orings it something and it /seemed/ like the suffix after the hyphen was designated by “type of object”.

and the prefix before the hyphen could be tied to the FICHE DIAGRAM numbers or something? i mean that 16-03 or whatever for the fiche diagrams must mean something as well?

i’ll run wikipedia on parts number diagrams and see if i can find something. but it seems like there must be some kind of key somewhere that he rmanufacturers have used to standardize the PNC...?

90916-03117 is the only thermostat available for the 1FZ engine in any variant worldwide.

____________________________________________________

A quick primer:

XXXXX-XXXXX is called a Part Number. These can be 10 or 12 digits.

16351 is called a Part Name Code. When a PNC has a letter next to it that means it's a part of the same assembly/system and thus has a similar PNC. So, PNC 16351 is the by-pass tube. 16351A is the oring that seals the by-pass tube to the head.

Make sense so far?

16-03 are sub-system page numbers for deciphering schematics in the different sections-- this was useful when parts professionals had to use micro-fiche readers and actual books to look up parts vs. the ease of a navigation system like the current Electronic Parts Catalog (EPC) we are lucky enough to have today so that everyone now thinks they are a parts expert.

The first 5 characters of a Toyota part number indicate area/system (generally) you are working in. 04111 will always be engine gasket kits, for example.

The 2nd 5 characters of a Toyota part number indicate (generally) the vehicle/engine model system you are working in.

Thus, putting them together you get: 04111-66036 will be an engine gasket kit for an 80 series with the 1FZ family engine in it.

Thus: 53341-90K00 would be a hood insulator (53341) that goes on a 70 series non-US Land Cruiser (-90K00).

Thus: 56121-90A05 would be a windshield weatherstrip/gasket (56121) that is applicable to 6x series Land Cruisers (-90A05).

Generally speaking, XXXXX-66xxx would indicate parts for an 80 series truck powered by a 1FZ.

xxxxx-90300/90800 would indicate parts for 4x series LC's.

xxxxx-660XX would indicate parts for 1FZ powered 80 series trucks.

XXXXX-170XX would indicate parts for engine parts associated with 1PZ/1HZ/1HD-T/1HD-FT/1HD-FTE engine components in 7x/8x/10X trucks.

XXXXX-0K0XX would indicate parts for Hilux trucks.

XXXXX-61010 would indicate parts for 2F/3F powered 4x/5x/6/7x vehicles

XXXXX-90A00 would indicate parts for 6x series vehicles.

XXXXX-68010 would indicate parts for 2H/12H-T powered LC's.

xxxxx-58010/56010 would indicate parts for B Family engines in LC's

And on and on and on.

For example:

58510-90K31-B0 would indicate the floor mat for the front of a 7x series truck that is colored gray.

Each auto manufacturer has their own system. This is Toyota's system that has been in place since October of 1963.

thanks a lot beno.

i appreciate your providing this so i can study up. it seems to makes sense when you are in there but it is a little elusive.

can i ask you this though please before sinking my teeth into all of it? i am using toyodiy and partsouq fiche. when i search for 03117 it /seems/ to bring me to the correct fiche diagram but there is no PART in the diagram with 03117 and there is no PART # shown in the text for this number. maybe i am missing it or have the wrong thermostat?

it only shows the 16331A number (if i am looking at the correct part) and the 03094 number in the parts list.

i mean, i need to print out your response and read it tomorrow when my brain is clear (so apologies if you answer this already) but i guess i am not finding the 03117 number?

i’ll edit this if i am sounding like a dope because you answer it here...

I answered it in my first sentence: 90916-03117 is the ONLY thermostat available for a 1FZ in an 80 series. That's it. There is no more thinking about it. Don't worry your brain over what the part used to be or where the 03117 comes from or what it does. You just need to know that the part number is 90916-03117 and the gasket is 16346-66020. That's it. And this happens when you click on a part on the EPC and it gives you a part number (10 digits).

YOU NEVER NEED TO ASK THAT QUESTION AGAIN.

90916 is generally the prefix number for thermostats (though not necessarily).

90916-03094 was the factory number that was superseded to 90916-03117. No one cares about 90916-03094 anymore. Because it's not available and hasn't been for awhile.

When you take 900916-03094 to a Toyota parts professional (good luck finding one) he will most likel say- "That number doesn't exist sir. It supersedes to 90916-03117. That part number is available. Would you like to order that part because I don't stock it." And you will respond: "Yes, I will buy the thermostat I need for my truck. Thank you."

OK. sorry i misunderstood that. apologies! the 94 was superseded by 17 and they don’t bother updating the online fiche i guess? that seems super bizarre if they have the correct number in the internal system. i guess a good reason to use a parts professional. but that seems crazy if the online system is showing the old number and not the one that superseded it (unless i am totally mixed up at this point...)...

Pirate catalogs such as Toyodiy do no have the same update support functions factory-licensed catalogs have.

If you want current supercession information, buy access to a licensed catalog.

hi CD.
thanks. apologies for any ignorance (if that is even necessary).
OK. so the online catalogs are not licensed and are “pirated”? that makes sense as to why they wouldn’t be updated. i was finding that super bizarre, obviously.
are the /dealer/ online catalogs current? i mean, i’m not used to this ecosystem but does toyota prevent retail online customers from accessing the current catalog? or they are current if you access them from a licensed toyota dealer?
THANKS
jon

 

[jdayment]

parts.toyota.com gives you the superceded numbers and best of all it's a Toyota site or even better by from someone like Beno he's not only going to sell you the thermostat but also the knowledge of what other parts you will need for the job
