Any std coolat is good then ther's racing type's but personally i wouldent buy them. ther´s other fun thing to throw yo' chash at.

no you dont just check tha seal on the cap to C that's whole(if not CHANGE or your car will overheat when you put tour foot down) and also check the spring.

I just use Caltex radiator coolant.... Its supposed to be a 50/50 mix. Flush your radiator, e.g. drop all your water out (undo the bottom hose on the radiator.... I think I undid the one going to the motor as it was easier then pushed the hose down to the ground). Put the hose back on fill it up with clean water (and radiator cleaner if need be) and start your car so it runs through and turn your heater on.then once its been running long enough pull that hose off and drop that water out.... once you have done that fill up with fresh coolant and water (premix it @ 50/50 or what ever the bottle says) and you will be sure that you have flushed it.

Cheers

P.S. Let your engine/radiator cool down before you put cold water in it as it may cause things to crack (expanding and contracting too quickly)

How do you bleed the radiator? I know where the bleeder is, but dunno how to do it exactly. Do you just fill up the radiator and leave the bleeder open until all the air bubbles escape then close it again?

Also how long does the water pump usually last? I'm just wondering if I should change it at the same time as I do a coolant flush with my upcoming 100k km service.

Not sure of the correct way but i just filled the radiator - then with the car idleing, unscrew the bleeder right out. it will bubble and carry on for a couple of mins. keep topping up the the radiator in the process.

carefull if the car is hot because the bleeder tends to spit a bit.

hope this helps some

if u use 33% usualy 3 years i do mine every 2 years on all my cars and its always very clean . when i let the old one out i flash the system , undo the bottom of the radiator and the screw on the engine block so it lets all of the old coolant out flash it with clean water blow all water out then fill it up again .

SKYLINE_PAUL, u say ur water is gone muddy, i had this problem b4, firstly the best coolant to by is just nissan coolant, when u flush ur radiator outby something that kills rust, the reason why ure water is so muddy is because u had to much water not enough coolant, after u have the new coolant in make sure u check the car over the several days because u may get a few leaks , mainly the water pump, and also keep checking the under the cap over the next few weeks to see if it stays green, i had to do about 3 flushes b4 i got the nice green colour back, urn cooling system is the most important thing on ur car,

the reason ur water is muddy is because at some stage before it had just water in it or the coolant was very old and infective , common with jap imports as they are not serviced in japan .

give it a good flush and use a good coolant ready mixed dont add any water to it . u can use any coolant as long as it is at least 33% and change it every 2 years .

Guys, how many litres of coolant will be needed do you think?

I've got 5 litres of 60 Plus (2 Years) coolant, and it says not to mix with other coolant or water.

I just dont want to get half way through the job and realise I need more and be sorta stuck with an undriveable car?

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
