to flush the radiator u dont neeed to remove it. just d/c the top hose and then the bottom hose. put a hose in the top and flush away. after that flush the engine by sticking the hose into the intake (top hose) and allowiing the watr to come out the bottom.
It will work better if you "reverse flush" the radiator. By adding water in the top, all you are doing is forcing the crap further into the cores.

Take it out, upend it and push water in the what is normally the bottom of the radiator.

hopefully have fixed my overheating probs will find out when i put the rad back in the car on the weekend . took my rad to work and sent it of to the guys that do our rads for our work . turns out it was about 40% blocked and the top tank wasent the best adding to that my thermostat was not working properly hardly operning in a boiling saucepan of water hopefully it's sorted .

on the other hand tonight my sons r33 looks like it has blown a hose behind the head somewhere will bring the pressure tester home from work tommorow and see what going on there .

this hot weather in adelaide is taking its toll atm . we have so many people phoning and driving off the street for aircon regass it's running us off our feet good for the boss i supose tho lol

and the funny thing is when its 30 degrees and i turn the a/c on after awile it overheats

if its 25 degrees outside i can turn the a/c on and it wont overheat

but when its 35 and over without a/c it overheats lol..............strangeeeeeee

not strange at all, the AC makes the motor work harder, the air con core in front of the radiator gets hot, and pases the hot air onto the radiator, theres extra heat under the bonnet... all taking its toll on the cooling system. If part of the cooling sys isnt working properly, then it all goes down hill.

well... well... the boys at thommo radiators found that my radiator was leaking pressure on the bottom of the seems

on order is a Just jap aloy radiator hopfuly there good i didnt want to spend 800 bucks for a genuine nissan one

Yeah I've got one of those from fatz.. had two tiny pinprick leaks on the upper front corner (in the welds) which I wasn't very happy about but not much I could do, just put some silicon on them and she'll be right.

I am however having slight over heating problems under certain conditions now that I didn't have before, new thermostat, water pump and radiator cap on their way so I'll put those on before I make any claims about the radiator. Most others have good experiences so I hope that it's the water pump/thermostat/radiator cap that is the cause and haven't wasted money on the radiator.

whooo hoooo all fixed took it for a spin today up the hills with the aircon on it's another stinking hot day in adelaide and the needle sat a fraction just under half and did not move at all . cleaned out rad and new top tank . new thermostate . flush all old coolent out and replace with new total cost around 200 bucks . im as happy as a pig in poo .

found the problem in my sons car why his overheated it has split the turbo water line behind the head looks loke a prick to get at and fix .

bugga he can wait till the weather cools down lol mines fixed thats the main thing lol

cheers mid life crisis

Whereabouts would i be able to get a new radiator cap for my car? what specs or part no. should i be looking for? Cheers...

i think you would have to get a new cap from nissan i think thats where i would go just to be safe

hey atleast you knoe you have the correct cap then

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
