is your fan still working properly sometimes they wear out or lose there fluid. a simple test is drive at 100km for long extended periods of time and see if your water temp goes down. is your pump still pumping enough flow this also could of broke down. just a few oter ideas to check out. just start eliminating one by one i like to start with the cheapest >_<

had similar issues with my 34 not long ago.

i went a new radiator, oil cooler and lower thermostat.

bit to spend but had no problems since.

factory gauge was little use compared to power fc which monitored much better.

Ben,

Let me know how you go with flushing the radiator please.

Will be taking it in tomorrow.

The machanic doing all my mods has checked the oil and it is all fine, so if this

doesn't work I will be getting a new radiator

  • 3 weeks later...

i just experienced the same problem and its just been fixed .... sorry for the long post but I couldnt fit it in 2 lines

car = r33 gtr

problem = oil temp up to 110-130 (normal driving), boiling coolant, water temp hitting 3/4 level at times (yes turning the heater on kept the temp to 1/2 way which was normal)

diagnosis from a well known tuner in sydney = free wheeling viscous coupling (so i ordered one from nissan at a cost of $440!!!) not happy jan..... + the cost of figuring out the problem $100

2 weeks into the wait and the same day the clutch fan arrives, the radiator starts leaking....so I baby the thing to the workshop (not the same workshop as mentioned above, never again!)

turns out the radiator is blocked (apart from the obvious leak that just started)

I ended up buying a new radiator from Justjap, change thermostat (old one was OK), changed clutch fan just because and i couldnt get a refund anyways (old one was also in great condition)

Now, my water temp is always below 1/2 way, oil temp just gets above the 70 mark on the gauge even with a bit of spirited driving and aircon on!!!!

Moral of the story, dont think a well known tuner can solve all of your problem! Had a feeling that the radiator was stuffed but decided to listen to the mechanics!

But what can you do, it is a GTR and I'd rather spend a few $ for someone in the know to figure things out rather than spending thousands to fix the engine!

I suppose its a good case of K.I.S.S hey? thanks for flling us all in .. as I am new to the concept of clutch fans ( as I am used to electric thermofans)

Just an update on my prob....

It ended up being the bloody radiator after all that.

Instead of flushing it out i just bought a new 40mm thick one from Just Jap. Couldnt be happier with the result.

Now sits on 81 degrees usually.

jeff....how many letter in the workshop's name?

$300 from Just Jap or UAS for a new one can't be beaten...I had to buy a standard (aftermarket pathfinder) one for the race car and it was 450 trade price.

i noticed people in this thread talking about oil temps.

My r34GTT never goes above 80 on the standard gauge. just wondering as this seems pretty low compared to the 100plus figures here

    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
    • You can use your VIN to look up the factory part number somewhere like amayama, and then look to order new if necessary. https://www.amayama.com/en/genuine-catalogs/nissan Depending on price you might want to rebuild instead. @GTSBoy I had an interesting insight into US market parts when the Titan rear calipers were sticking. New calipers were dirt cheap, about 20% more than a rebuild kit....they are just considered throw away maintenance items
    • Funny, but really not funny. Thank god (most) f the world has moved on since then
    • Lots of votes for driving onto a plank first; that is the quickest way I've found, 25mm is enough for my case but that will vary by car It also depends where you are going for. On the 32 I can get to the rear diff with my floor jack if I do that end first, and get it up on stands. Then I lift the front from either front tow hook as high as needed, also onto stands. Sometimes I need a small lift on the other tow hook to get it level enough If I do the front first I can't get to the rear diff because of the angle of the car Other options are getting to the front mount of the rear subframe from in front of the wheel (if only lifting one side, or just do both which is a bit of a pain compared to one lift from the diff), or also the gearbox cross member mount on the driver's side if you are  just trying to lift the driver's side. I This is the jack I use; it says 75mm clearance but of course that is only on the lower section so if you have to reach too far in like the diff you still get stuck. https://www.snapon-bluepoint.com.sg/category/Floor-Jacks/product/Floor-Jack,-2-Ton-Low-Profile
