Hi, I just find out my 34gtr's water temp was up to 95-98 degree? is that normal?? but when i drive on highway there is only 77-80 degree.

thats really a big different between more air flow and less air flow.

I checked my fans its working good.

anyone can point out is this normal??

thanks!!

depends on where you fit the water temp sensor and atmosphere temperature But seems pretty normal to me.

98 degrees seems normal??

How did you test you fan, with mine it spins but i can stop it and even spin it backwards when its up to temp, this means its screwed, could be your problem as well.

Oopps Didn't notice its a GTR 34. if your stock Gauge displaying 98 degrees and on a slow rising mode then might want to check for water leaks or thermo related bits

Hi there is no leaking, the highest temp is 98degress, it will go down to 94 and rising up again.

but if the car runing the water temp will go down very quick. about 77-84 degree if drive normally.

i can see the highest water temp on the center screen is show up 98 degree in heavy traffic, but the standard water temp gauge only a little bit more than halfway.

and if the traffic flow is good or on the highway, the temp is about 80 degree, on standard water temp gauge is about halfway.

No expert on R34 GTR's, but any car that registers above half on the stock gauge isnt a good thing?

Maybe your thermostat is stuck slightly closed, so when your in traffic its not quite opening enough for full flow.

Id try that before doing anything too drastic. Flush the system, new thermo, some good coolant..

98 is to hot for just normal driving on a daily basis for any RB. I don't know what hypergear is talking about. Did you try bleeding it to see if there is any air in the system?

Ive never seen above 90degrees, mostly 82.

only time i saw 89-90 was on a 40degree day during summer so i drove with my heater on full blast; took the temp down to 86-87 quite quick although heater + 40degree heat was unbearable lolz.

i agree with everyone, coolant flush for air pockets and new thermostat

the 98 degree only happend once on havey traffic. the car only run 300m in one hour.

in normal drive condition the water temp only about 75-85 degree. even i drive very hard the water temp still not go over 85.

and the fans is also OK. so I guess its normal if the engine is on and stay there for one hour.

the water temp only go high when the car doesn't move for a while.

98deg water temp is ok, it is a little high (check basics) but it wont kill the engine etc

just drive it normally once you are able to and the radiator has some airflow

once you drive it normally with airlfow, the temp should drop pretty reasonably to mid 80s

the ECU has correction based on water temp and will start taking out timing above certain levels

if water temp is near 110deg i would be worried - the stock guage cluster should be near 3/4 at this level

thanks mate, so when the water temp up to 110, that mean problem?? or it will break some think?

You can warp the head for one. 98 isn't going to break anything, but it's higher than it should be. Mine gets a bit to hot one hot sunny days with the a/c going after I've been creeping along in traffic for too long. I turn the a/c off when it gets over 100 to let it cool back down. usually around 110-115 your coolant will start to boil.

Your coolant temp is very high for an RB engine, in heavy traffic I rarely go above 90c (13B-REW).

I'd have your lines bled and replaced with new coolant. But as stated in the thread your engine won't get damaged sub 120c, but you shouldn't be around that temperature at all even under extreme engine stress.

get the radiator professionally cleaned and a new top tank. should be 230-300

they take it out, take it apart, clean out all the crap etc. good as new. a new OEM or nismo thermostat is a good idea at the same time. The generic ones are very flimsy in comparision. nissan is ~50$ trade price. 82deg where the nismo is 72deg

You can easily mod the engine fan to pull more air and not have it locked on. They lose some of the silicon oil thats inside the fan hub over time. You can drill holes and refill them. Mine was doing the same thing although i would check the basics first and change the thermostat if it has been a while.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
