Radiator flush question

Hey Guys,

Trying to clean out my radiator and engine.

1) Is it safe to remove the top hose, run the engine, then fill the radiator up as it pumps the water out of the enginge, then once it's all clean, I can then shut the engine off, fill with coolant?

2) Assuming (1) is safe, how long can you run an engine without water for? Can you do it at all? Like can i wait till the water is coming out clean, stop putting water in the radiator, wait till no more water comes out the top hose, then shut the car off? Or will that cause damage? Obviously it will need to be warm as the thermostat will be open...

3) Do I need to use the drain bolt on the side of the head? Can someone tell me where it's located? It seems the RB26 is a difficult job, is the RB20 that difficult (couldn't find a rb20 guide)

4) Where is the thermostat located...maybe I can just remove it, and just use hose pressure to clean thru the engine? That way I can do it cold/not running?

5) Other suggestions?

Thanks guys

Chris

You dont need to do that at all.

Take off the radiator cap, Undo the drain at the bottom of the radiator and Take off two hoses near the head and get a hose blow water through so it goes through all different parts of the cooling system. It would be a good idea if you are unaware of the condition of the radiator take it somewhere and get flush out prob cost you like $70.

      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!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      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.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      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.
