Howdy all,

Long time lurker, second time poster. I got a r34 Gt and lately it seems to be heating up real quick after only a few minutes of driving, where i, and any passengers in the car, can feel a noticable difference. I also popped the bonnet after a 40 minute drive and i could smell a faint odur of burning.

This has just started happened recently where the thermo. says that the engine temp is somewhere in the middle. I know this is a rather noobish question, but just wanted to get some opinions on what i should be looking for, eg. coolant levels, some part that might need replacing. etc.

Start with your coolant level, check the radiator, see if there are any leeks in radiator hose.

It could be your engine coolant temperature sensor located on the water outlet, or the auxiliary electric fan motor may not be working..

Check the Malfunction Indicator Light .. if its on when you start your engine then one of the major sensors in the engine control system is not working properly. Most likely engine coolant temp sensor by what you've described.

Anna is better then I, as I'm still not sure what you even describing.

When you say, your car is "heating up quickly" and that "your mates can feel a noticeable difference" do you mean the water temp, as thats sposed to get up to temp (half'ish way'ish on the gauge) quickly. Or do you mean cabin temp, with the heater on?

The dash cluster w.temp is really only a slow reaction "three step" unit. Cold / Normal operating temp / Hot. You shouldn't see normal small fluctuations (to stop the average commuter from freakin out).

Would help if you could describe the issue some more :P

Check the obvious as posted above first, like do you have enough fluid in the radiator, has it gotten so hot that its actually boiled out of the overflow...or do you just think its hot?

Do you have a power FC or an aftermarket gauge for checking the degree of the coolant?

Since you said you "popped the bonnet" I'll assume your talking about the engine bay :)

There is a bit of info on the forums, from what I've seen, although I don't claim to be an expert, if the engine coolant is really getting hot (as in really hot) you *could* have:

*Blockage in the radiator

*Problems with your water pump

*Problems with your clutch fan (ie. the fan on the front of the engine).

*Air in the lines of the radiator(?)

With the 3rd one, an easy way to test is when the car is hot, pop the bonnet and turn the engine off, if your fan keeps spinning for a long time then the clutch/viscous coupling *may* be gone.

If it stops spinning immediately then its fine.

Another way is to get the car warm and before you start the car touch the fan gently with your hand or similar and get someone to start it, (don't put your hand right into the fan or anything), if your fan has no resistance when the car is hot then your clutch is gone and you should consider buying a new one. *** I did have this problem and the part was $300 from Bursons.

However having the clutch fan go is one of the less common problems that happen, when was the last time your radiator was flushed?

And did you use the bleed valve of the top of the engine?

And before I get flamed about the above, I'm just trying to help, and yes, I have put my hand on the fan before starting the car, yes my hand is still intact (when the fan was not working it wouldn't move with 1 finger on it) :(

    • Got the gearbox in and the front drive shafts.
    • Hi There I went through a rabbit hole of reading about Xenon headlights and the ADR regulations for having them installed. As people have been defected by running factory xenon I was researching in ways to make them compliant. Everyone always say needs to be self leveling and have washer installed, which I don't necessarily agree with. For this argument I'm using R34 as reference as I'm more aware on the construction of the headlight compared to the R33 Xenon, which may still be the exact same case.   For the self leveling clause taken from ADR 13 - Installation of Lighting and Light Signalling Devices on other than L-Group Vehicles As you can see the bold text "these manually adjustable devices from driver seats" are fine to use. As Series 1 Xenon model headlights do have a 4 level adjuster on the right near the ignition (however not series 2) then these model are consider compliant in that argument.   For the Self Cleaning aspect of this argument clause taken from ADR 13 - Installation of Lighting and Light Signalling Devices on other than L-Group Vehicles Now i can understand the argument that Xenon will need a washer as they are over 2000 lumens, but I clicked on the 12 at the end of that sentence and it takes me to the end notes which states R34 for headlight lenses are plastic, not sure if PL is mark as I don't currently have my skyline to confirm that marking is there. But could you not technically get a lenses with the PL marking on it and then get away with the argument that you need a washer. I went through a quick read of the adr and might have missed something else that may cause them to be non-complaint.    But wouldn't these technically be complaint headlights   Would love to hear other people input on this and shed some light   Edit In regard to the the washer portion I might be mistaken ADR 45 (which I believe is Regulation NO.45) states 12 cd (candela) I dont understand that portion in regarding to calculating the candela if anyone can shed some light. Otherwise I guess throw in a washer for the headlight and you definitely comply.
    • Took it to all Japan day, flogged the hell out of it and took it all, am a very very happy man  don’t know how that ended up in Greg’s thread before
    • Hey Nismo, any chance in the world you still have these seats?
    • I'd say closer to OG GTX3582R, just smaller trim - so 59mm inducer/82mm exducer as opposed to 62/82 for the first gen GTX3582R. Yeah EFRs were boss, the EFR8474 is still an absolute beast and it perplexes me that people still go to things like Turbosmart/Garrett etc when the results people are getting with those are pretty unremarkable compared to what you could get with a turbo available well before those options came out.  DriftSquid (I think) "upgraded" from an EFR9174 to a Turbosmart turbo and promised a comparison video - and kinda shuffled awkwardly and did a bit of diversion from the fact that they didn't get any improvement going to the currently massively hyped brand of turbo from a turbo that was a bit of a frankenstein that had been well superceded in it's own range before the Turbosmart unit he put on there even came out. I suspect the EFR would outperform most Xonas for what a lot of less-insane RB owners would go for, in the 400-600kw range but the Xonas are looking hard to beat up to maybe in the mid 700kw range at this stage- basically where EFRs don't really reach, and before the Precision turbos take over.  What the Xonas do well in the "EFR range" is be easier to package etc, and work very well if a divided housing doesn't suit your application.
