Hey, i've got a 2003 skyline v35. a couple of months back when it was about 40 degrees the coolent started to boil and spurted out which created havoc with the air con. ever since every now and a again when i start the car i hear this

water sloshing sound in front of the dashboard. anybody know why this happens? or experienced this before?

any advice on what i should do?

thanks a lot.

Is it still losing coolant? Sounds like maybe the heater box is leaking coolant into the ducting.

Can u smell coolant with the heater or aircon on?

hey i haven't really tested it. what is it meant to smell like? i'll try it and get back to you.

i called nissan service center and they said they won't look at it cos its an import, something about how they're computers won't sync with mine :(

i called my dealer skyimports in melbourne and they said they'll have a look on tuesday.

is it still ok to drive it around? how severe is the problem? i clearly dunno much about this.

thanks a lot btw.

... what is it meant to smell like?

^ ^ ^ a bit like 34 minute-old ejaculant on floor of passenger footwell :P

see if coolant is leaking behind glove box where heater core might be

shut off heater

refill coolant before driving and take spare water with you whilst driving until it's attended to on tuesday

if you arent leaking water, it means you havent bled your coolant system properly. the sound you're hearing is the water moving around in the air gaps inside the heater core. bleed your coolant properly and it should go away.

hey thanks, yup there's nothing leaking atm.

i'm new to all this. is bleeding the coolant easy to do? what does it involve doing?

thanks a lot.

you need to get all of the air out of your coolant system. it involves filling up your radiator, letting the car get to operating temperature and revving the engine to about 3000rpm every now and then while still keeping the coolant topped up. you need to keep an eye on the temperature, making sure it doesnt overheat.

you need to be doing all of this while the heater is on full heat @ full fan speed. when it seems like its not releasing any more air, close the radiator cap, let it idle for a little while then crack the bleeder nut which is at the highest point of the cooling system.

if its your first attempt i suggest searching 'how to bleed cooling system'. or get it to a mechanic to sort out.

this has the potential of doing a bit of damage if temps get too high so be careful and dont be afraid to turn the car off if you feel like the temperature is getting too hot.

hey thanks for all that info.

i did go see a mechanic today. we tried running the heater on to verify the sloshing sound but nothing happened. because its intermittent and the mechanic couldn't hear it, he asked me to come

back if the coolant runs low (?). i mentioned bleeding the coolant but he said that he can't confirm anything at this point.

would you recommend getting a another mechanic to check it out?

thanks!

Need to get the air bubbles out of the coolant mate.....happened to me with my old 180sx when I installed a new PWR radiator.

I bleed the system but it still had bubbles in the coolant, just keep bleeding it over the next couple of drives and should go away.

Also I squeezed the radiator hoses to push the air bubbles out which helps.....and you need to get the water hot enough to open the thermostat.

I normally cut a 2lite bottle in half and tape it to the top of the radiator so the water level is higher than the engine which helps push the water down.

get any brand but make sure its concentrated or get a 50/50 blend. some do a 30/70 on non turbo cars (30 coolant/70 water). its up to you which one you go for - its just an anti-boil/freeze additive.

you'll find that the concentrates are a little cheaper than the pre-mixed stuff.

another quick question.

i've currently got the coolant tank filled with water. above the max cos i didn't know any better lol.

when i've got the coolant, can i mix it with the water? OR wait till the water evaporates and then fill it with coolant?

thanks a lot for ya replies.

you dont need to put anything in the reservoir tank. if its over-filled then it will just drain if your fuel cap ever releases any pressure. its not something you need to fill up.

just concentrate on putting coolant into your radiator.

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
