1uz Hydraulic fan pumps - No it's not the waterpump.

- There is lots of confusion about the extra pulley on the front of the 1uz-fe Toyota Engines. Some think it's the water pump , No it's not a waterpump, some think its a engine oil pump , no not that either. Its for the cooling fan , yep ,a hydraulic fan pump. watch the video to find out more.
I have a "95 SC400. My high pressure hose to the pump is leaking. My car is at The Car Care Nuts shop in Chicago. That hose is unobtainable. He has purchased 4 used hoses trying to find one that doesn't leak. A shop local to him quoted him $1200 to make one. The 4th hose is enroute to him now. If it doesn't pass pressure testing he is going to ship me one of the bad ones and I'm going to a local shop to see if they can beat his $1200 local quote. Parts scarcity has me seriously considering selling the car as bad as I hate to. Incredibly clean, 115K miles, just a gorgeous car.
I had no idea there are so many different variations of the hydraulic fans. My SC400 has a hydraulic fan and I love it. My Gs400's and Gs430 have electric fans.
The hydraulic fans certainly move lots of air. My understanding is once they when 3uz the hydraulic fan was no longer used. Well ive only seen electric fan 3uz anyway. Two more arrived last week for upcoming jobs. Is your gs400 a vvti? Cheers
Love the content! Shout out from Arizona!
Cheers. 1uz in planning or you have one already?
CartuneNZ already have just wanna know more I have a 1992 sc400 has 144k miles
Cool as. Did you find my sc400 /soarer tidy up and header fitment video? Cheers.
CartuneNZ no I have not I will watch that right now!
Thank you. This was helped me alot.
Glad it helped!
shout out from the states!!
Cheers. Do you have a 1uz? or hope to?
@@CartuneNZ I have a 4runner with a 5vz and hope to change it over to a 1uz when it gives me enough reason they are very cheap to source here in the states. However I am more inspired by your knowledge and passion then the motor specifically 🙏
@@CartuneNZ very much into Toyotas as a whole and working on them and knowing the ins and outs of the motors and systems
@@SunBitSynergy Thanks. Im doing a hilux atm which was 5vz but getting 1uz. Attempting to do whole conversion video. Cheers
whew! i did the LS400 idler to delete the hydro pump, but my pulley wheel off the hydro pump doesn't fit, i just need the wheel, where do you find the correct wheel?
Should I be able to grab the hydraulic fan while the motor is running? Recently noticed slowly overheating while sitting. Grabbed my fan and it fully stopped and didn't spin until I pushed it.
This video is great. I am chasing one of those hydraulic fan pulleys for my uzz30 soarer. I can’t find one anywhere here in Australia. Mine is a bit worn and it could be the reason why I keep shredding drive belts as they push back towards the motor. Any suggestions would be great?
Read somewhere that the hydraulic fan pump can be repurposed as a power steering pump... always wondered how true that was.
The stock pressures are quite different between the hydraulic fan pump and the powersteer pump. It is quite likely possible to do some mods to the fan pump in the valving to allow higher pressures and you have some control using the solenoid. I've never tried and never seen it done myself yet. Most of the time if we can't fit a powersteer pump then an electric unit is the solution which we go for. cheers
Can the usa ls400 fan clutch housing non hydraulic work with the jdm 1uzf20 hydraulic housing
Is this hard to delete the hydrologic fan set-up from a 91 soarer??
Shout out from Boston
hello Back at you. Cheers Kelvin
Hi. Got a Celsior VVTI ‘98. It running hot. Has slow hydraulic pump. Which parts do I need to run a normal fan? I kinda saw the parts you sold but can’t understand how I would use em to Solve the problem. Car has been sitting for 18months. 140000km or so on the mileage.
Kelvin isn't from this planet
Kelvin, if I have a hydro fan can I replace it with a fan pulley? Can I still run the same fan?
If you have a hydraulic fan, and you replace the hydraulic pump with a fan idler pulley the hydraulic fan will no longer operate.
hey! i just came across your channel and you’ve been really helpful with troubleshooting my car. i have a 92 SC400 that overheats while at idle, but not while driving. it also stutters quite a bit unless i floor it. any ideas of what it could possibly be? cheers from vegas!
Hello. I do some testing. Overheating at idle and not while driving indicates an air flow issue , most likely due to a fan not working. I would confirm the hydraulic fan is cutting in at idle and flowing plenty of air. Its possible to power it up directly to test too. Spluttering I would check fuel flow on both low and high speed , check fuel pump controller , ecu and AFM. Cheers Kelvin
@@CartuneNZ thank you! i probably really need to change the fan, and then i also learned that i have a misfire. my mechanic says it’s probably the spark plugs or coil packs. im gonna try to work on it myself! not a bad project car at all haha
How can I buy a 1uz wiring plug n play
My 1993 SC400 has hydraulic fan.
Hello. I beleive the usdm Sc400 had hydraulic fans like all the jdm soarer which also have the hydraulic fan.
i have a 00 ls400 im going to attempt to remove that whole assembly and run a smaller belt , wish me luck
When I do it I replace the hydro pump with a different idler unit which I keep here , especially if Im keeping the A/c. Is super simple. Cheers Kelvin
Heya, this sounds like what I need to do. But as a Wizard you speak to fast for a non mechanical guy like me 😉.
Why do I need an idler? Do you sell them? Then what else for the conversion? Am in Africa so getting parts is a mission ( I just have a weakness for the creamy 1UZ)
hey buddy. i have a 1uzfe ls400 non vvti. someone told me mine is clutch type. do u know if this is correct? how would i know if mine is bad or needs replacment thnx for all ur knowledge.
Generally the Ls400 have the viscous type fan. Easiest way to tell is open the bonnet and have a look. There is a simple test by stopping it turning as engine warms and when hot you should not be able to hold it still. Dont use your hands as it can do harm if you dont know how to do it correctly. If unsure best take to a mechanic. Cheers Kelvin.
Hey do you ever use these water pumps on your hilux conversions? Or is there not enough room? Sorry I mean hydraulic pump 😂
I have on the 2004 hilux onwards as they have a bit more room. The 3uz prado and fj40 also have one on them. Early hilux is a bit tight without frontal mods so rarely used. The fans work really well. Cheers Kelvin.
Do you rebuild these hydro pumps for customers? if not can you recommend someone
Most of the time I've had second hand ones to solve the issues I've seen through the workshop. The parts cant be prrchased through Toyota any more so its a matter if matching aftermarket seals. I don't know of anyone completing this job for other people. Had one customer rebuild his own units successfully. Cheers Kelvin
come on ....just admit it....you're the WIZARD OF UZ
That's brilliant. Best thing I've heard all day. How much trouble could I get in to from Warner bros if I start calling myself the Wizard of UZ? haha. Cheers
That's funny shit right there! I don't care who you are! Howdy from Texas Kelvin.
Hello Bill. Hope your are well. Have you found some motivation and time to get into one of your 1uzs? Laughter is great for us. I have to edit some of our workshop antics out as they might be taken the wrong way. Haha.
Do you happen to know the part number for the solenoid valve that goes on the pump for 93 sc400 or soarer
I use Toyodiy.com for finding all my part numbers, and its available to everyone, with pictures. That way you can put in your exact model and sub model to ensure correct part number.
@@CartuneNZ thanks for the reply I Tried using that site earlier after watching your video, and didn't get any pictures. Will definitely go back and try again
@@shyne229 there is a trick to pictures. Find my facebook, flick me a message, Ill work magic
Is there a part number for the shorter serpentine belt once the hydraulic fan pump is removed? I have a 1uz off of an 92 sc400
I used 6pk1555 , 6pk1560 or 6pk1675. cheers
@@CartuneNZ is that with or without the use of the ac pulley?
@@julian-ey3gr that's no air conditioning. If I remove the hydraulic fan and are still running air conditioning then I fit another pulley to replace the hydraulic fan pulley and the stock size belt still fits
@@CartuneNZ ok then I guess my question is … can I run the engine without the air conditioning/compressor pulley and without the hydraulic fan pulley. If I can do that then what belt should I be using?
I frequently run them without hydraulic fan pulley and ac pump, part numbers for possible belt options are above.
So would a 97 fan bracket fit a 98 vvti?
Yes, but not ideal due to the change in the top cambelt cover design.
@@CartuneNZ it fit perfectly. I got the car up and running again
3.38 😎
I thought I had left something in which wasn't meant to be there. Nope. That was all fine. haha. Cheers
My 91 ls400 had electric fans hydraulic fan is new to me
Hello Ryan. Its tricky for me as different models in different markets dont always follow what we see here. Do you think yours is standard with electrics? As ive never seen that on an early LS. The norm is viscous on engine with electrics on front of rad for a/c . Sometimes I trace numbers back but even toyota listings arent always right. I'd like to see some photos of yours. Cheers.
