This thread is full of WIN!

Thank you, I've been looking into doing something like this for awhile now and you just made it a lot easier.

Edit: What specific years was the oil cooler offered on the camry? and... Why do you have to modify the camry oil retainer bolt? I don't understand why it's not the right length to begin with, seeing as it's the same length cooler and theres a new union in place. I'm sure there's a reason I'm just missing it.

Thanks again!

 

that oil cooler is for the 5S-FE. it also came on 6th gen celicas and MKII MR2's. this is a great idea. ill give you credit that i didnt think of this! Props to you!!!!!:applaud::applaud::applaud::thumbup::thumbup::thumbup::headbang::headbang::headbang::bowdown::bowdown::bowdown:

 

Well, I didnt think i would have to modify the the bolt either until i went to bolt it up the first time. When it tightened up there was about a 1" gap between the oil pan and cooler. The 5s-fe block is sunk-in where the cooler mounts and the 2zz is almost flush with the sealing ring. I also ordered a lotus bolt that is the right length but it is the wrong diameter. It could be turned down on a lathe to work but modifying the 5s one was easier since i dont have a lathe at work.

 

soyou shaved down some of the threads on the long end? do you have an oil temp gauge? im interested in how much this is really working.

 

hey guys are these the US part numbers?

 

We need US part numbers in this thread asap!

I've poked around rock auto but have had not luck and the dealer's are useless around here unless you have a part number in hand.

 

hey how much you get yours for?

 

I got to oil cooler and bolt in the junk yard for ~$10 off of a mid 90's camry with the 5sfe. You dont wanna buy the oil cooler at the dealer, it cost over $500.
The union was ~$20 shipped from japan. You cant get it in the US dealers...i tried.

I dont have an oil temp gauge to see how much this is helping but since it came stock on cars in japan and Europe i figured it couldnt hurt. The only reason i did this was because i do track days in this car. It also helps warm the oil up faster on cold days since it always has coolant going through it.

 

thanks for the writeup

 

If smay commends this man. It deserves sticky.

 

Great write up thanks

 

any way you can get that union here in the US. plumbing store?

 

Great! I'm thinking about going this route

 

:thumbup:

 

Will this work on 1zz?

Only ask because the trd(same style) states it is for 2zz only?

Looks the same?

 

If the 1zz has the coolant pipes then it will fit the same i think. I dont have a 1zz to look at though.


For everyone that doesnt have google, you can order the union through http://www.amayama.com/. Took about a month to get and you can use paypal. Cost me around $20 shipped

 

it will fit on the 1ZZ, thats not a problem, its finding the coolant lines to feed off of. another option for coolant lines are the throttle body lines. instead of going through the TB go through the oil cooler.

another issue that comes to mind is that newer 2ZZ block have a freeze plug in the block instead of that nipple. so it will need to be knocked out and tapped for an AN fitting.

 

Smaay, what do you advise to route the 1zz coolant to the oil cooler? You said instead, why not after the TB, or from the coolant reservoir?

i have tried to find thencoolant flow diagram. I found this:
https://www.celicahobby.com/forums/...om/forums/ubbthreads.php/ubb/download/Number/29287/filename/coolant-diagram.jpg

But the drawing from the 1zz is to small to see the direction through the coolant reservoir.

 

ahhh, long live the early model 2zz. Lift at 6k and bolt on oil coolers!

 

dammit. another thing im eventually going to spend money on.

 

we have these fitted stock on euro models - technically speaking they are heat tranfers not coolers. Mocal makes a proper oil cooler for the 2zz as fitted to the TTE Compressor model which would be the route i would take for track days as i dont think these "heat transfer" offer much advantage. if anyone is considereing a oil cooler go for a proper one that opens to a oil cooling rad by a thermo valve.

 

instead of going through the TB, go through the cooler

 

Well i searched à lot. I cant find à drawing of the coolant flow which is right. The link i provide earlier is not right. The 1zz coolant reservoir in the drawing has 4 attachement, mine have 3 like the 2zz


this one neither is correct for the 1zz.
https://www.ddperformanceresearch.c...nceresearch.com/admin/pdf_files/DDPR_INFO_TOYOTA_2ZZ-GE_COOLING_SYSTEM_INFO.pdf

Its à very Nice description. I assume its right for the 2zz. IT looks à lot like mine (eur 1zz-fe). Exept in my case the pressured line that goes to the coolant reservoir comes from the feeding line of the throtteboddy.
IT looks like its done so that when the engine is cold there wil flow coolant through the throtteboddy. When the engine is warm there flows no coolant through the throtteboddy.

Actualy i don't know whats happening in the coolant reservoir?

The thing is, in cold and warm operations there should be enough coolant flow to exchange enough heat. The lines through the TB looks a little small. So i want to pick the right feeding line.

 

Cooler? Coolant reservoir/tank? On with Side?
Between the coolant tank And the TB or the coolant tank And the waterpump?

 

What does the Oil cooler retaining bolt 15690-74030 do. I mean is there à valve inside? My thinking is that is should have no holes because iTS the return way off the oil (atleast in case of à sandwichplate)

 

This mod would love to be paired with a filter relocation/oil cooler kit. You would retain a safe clearance under the car, and have substantial cooling.

 

Well i want to install this oil cooler on my turbo 1zz-fe.

I have this (from à eu 2zz).

Even the black bolt. Bult the seller mentioned that this is not the right bolt. IT should have à valve (and holes) inside.
What i can find is that for the 2zz the 1569588411 should be the right bolt but in some catalogus the 1569522010 is mentioned to.
For the 1zz-fe mr2 (eu zzw30) only the 1569522010 is mentioned.

I cant find real pictures of both bolts. So i dont know the difference of those 2 bolts

From what i can find from drawings and descriptions of the bolts, i think the 1569588411 had holes And à valve (like descripted in this thread). I think the 1569522010 has not And is the bolt i already have.

I am not sure. Does anyone know?

Other question related to the bolts is how is this intend to work?
The solid bolt à understand.
The oil comes at the outside. Goes through the Cooler. Than through outside of the oilfilter, the filter material to the inside. Than through the Black bolt back to the engine.

But how does the one with the valves intend to work.
I can emagine that this is ment to create à bypass when the oil has to much resistance through the cooler. Why i think this is because it shall be à real challenge to seal the bolt with the union bolt. IT look like this is not the intension. There is no gasket or washer in the drawing between the oilcooler And the union bolt. So iT looks like the intention is that there can go oil. Only concern is that in case of the solid bolt this oil stands stil ( not flowing).

Can someone give à clear explenatoin of the intended working please?
