Hey boyz and girls,

Just wanna get an opinion on types of coolant to use in a GTR. Any particular brands that are good? what ratio mixture should be used?............just want to make sure that coolant types are not detrimental to coolant lines, seals, pumps etc...

Got a mate who recently had coolant changed and was using a 50/50 mixture but car had a syrong coolant smell after the drive................is that normal?

Cheers.

Smell because while ur mate was filling the radiator up he might spill some on the engine?

Anyway, i think the best is to use NISSAN genunie which available from most Nissan dealer.

redline coolant with inhibitor (pink in colour) with distilled water. good flush out to get rid of the glycol base from previous coolants + rust dirt general crap etc. the stuff works good with glycol, but better without it. or any good quality 50/50 glycol (the green stuff)

i currently have power steering fluid in my raditaor and it hasnt overheaded! (still not reccomending it!)

Redline Water wetter is not recommended for winter used, only suitable for summer or track use. If you must use RL WW, pls mix at least 15% coolant and the rest distilled water.

Power steering fluid or ATF in radiator is a major no no. The viscosity of the fluid usually 7cSt or more will decrease the heat transfer rate of the medium (fluid) by hell of alot.

General guide

PSF or ATF ~ -50 to -70% decrease heat transfer

50/50 coolant/water ~ normal heat transfer

RL WW/100% water ~ 50% better heat transfer

i used 2L of genuine coolant from nissan to replace all in my GTR block , radiator and hoses. Make sure u use green coolant. and just use the genuine. if ur too cheap to use a $12.50 per Litre bottle of coolant. then ur prob too cheap to own a Skyline. its gonna be an expensive piece of work.

not a good idea to run power steerin fluid in ur coolant true. im not doing it by choice people. NEVER use power steering fluid in ur cooling system

i dont know hows its getting in there but it is. the mechanics trying to figure it out

Thanks for all the feedback guys. Just flushed the system and gone 50\50 Geniune Nissan green stuff and demineralised water..............only the best will do!

I checked out the Nissan stuff, I was actually suprised how well priced it was. Very similiar to that of good aftermarket gear.

I'm currently running the Nulon green. I did a little research in to what is required in a good coolant and it had good levels of the good stuff. :P

The nulon green stuff is definitely a good bang for buck coolant.

I prefer Nulon's Concentrate because you know you are getting the right ratio going in. Ie 2.5L for a 7L car.

The problem with premixed stuff is that you'd worry about water left in the block which causes dilution. You'd be suprised how much water stays in the block if you dont drain it out.. like a few litres!

I agree, Nulon's Green Concentrate at 20 bux for 2.5L is by far the best bang for your buck. 5 year protection too. Sweet.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      The engine stuff is Greg Autism to the Max. I contacted Tony Mamo previously from AFR who went off to make his own company to further refine AFR heads. He is a wizard in US LS world. Pretty much the best person on earth who will sell you things he's done weird wizard magic to. The cam spec is not too different. I have a 232/234 .600/603 lift, 114LSA cam currently. The new one is 227/233 .638 .634. The 1.8 ratio roller rockers will effectively push this cam into the ~.670 range. These also get Mamo'ified to be drilled out and tapped to use a 10mm bolt over an 8mm for better stability. This is what lead to the cam being specced. The plan is to run it to 6800. (6600 currently). The Johnson lifters are to maintain proper lift at heavy use which is something the LS7's supposedly fail at and lose a bit of pressure, robbing you of lift at higher RPM. Hollow stem valves for better, well everything, Valve train control. I dunno. Hollow is better. The valves are also not on a standard valve angle. Compression ratio is going from 10.6 to 11.3. The cam is smaller, but also not really... The cam was specced when I generated a chart where I counted the frames of a lap video I had and noted how much of the time in % I spent at what RPM while on track at Sandown. The current cam/heads are a bit mismatched, the standard LS1 heads are the restriction to power, which is why everyone CNC's them to get a pretty solid improvement. Most of the difference between LS1->LS2->LS3 is really just better stock heads. The current cam is falling over about 600rpm earlier than it 'should' given the rest of my current setup. CNC'ing heads closes the gap with regards to heads. Aftermarket heads eliminate the gap and go further. The MMS heads go even further than that, and the heads I have in the box could quite easily be bolted to a 7.0 427ci or 454 and not be any restriction at all. Tony Mamo previously worked with AFR, designed new heads from scratch then eventually founded his own business. There he takes the AFR items and performs further wizardry, CNC'ing them and then manually porting the result. He also ports the FAST102 composite manifold: Before and after There's also an improved racing crank scraper and windage tray. Helps to keep oil in the pan. Supposedly gains 2% power. Tony also ports Melling oil pumps, so you get more oil pressure down low at idle, and the same as what you want up top thanks to a suitable relief spring. There's also the timing chain kit with a Torrington bearing to make sure the cam doesn't have any thrust. Yes I'll post a before and after when it all eventually goes together. It'll probably make 2kw more than a setup that would be $15,000 cheaper :p

      Because the cars wheels are on blocks, you slide under the car.   Pretty much all the bolts you touched should have been put in, but not fully torque up.   Back them off a turn or two, and then tighten them up from under the car with the wheels sitting on the blocks holding car up in the air.

      Yes. Imagine you have the car on the ground, and you mine away all the ground under and around it, except for the area directly under each individual wheel. That's exactly how it'd look, except the ground will be what ever you make the bit under each wheel from

      Yes, if you set the "height" right so that it's basically where it would be when sitting on the wheel. It's actually exactly how I tighten bolts that need to be done that way. However....urethane bushes do NOT need to be done that way. The bush slides on both the inner and outer. It's only rubber bushes that are bonded to the outer that need to be clamped to the crush tube in the "home" position. And my car is so full of sphericals now that I have very few that I need to do properly and I sometimes forget and have to go back and fix it afterwards!
