Hi,

I've done a fair bit of searching but have come across a variety of answers, so would appreciate a bit of help.

1.I had the coolant changed when I bought the car (6 months ago). The resevoir tank came back quite low, so I topped it up with demineralised water, about 400ml and its sitting halfway between full and low. Would this affect the properties of the coolant to a significant degree, or is it ok to leave as is--not sure if I really need to change the coolant.

2. I've had a look here/workshop manual/youtube at the flushing procedure. Either now or eventually I'd like to do it myself. The workshop manual/youtube videos seem to just drop the old coolant out and replace it, without really flushing it (is this what most workshops do)?

I'm not keen on trying to remove the drain plug on the block, I think it might best be left alone!

Basically what I'm thinking of doing is:

1. Ignition ON, heat 32deg, drain coolant, remove resevoir tank and coolant.

2. Install resevoir tank, drain plug.

3. Ignition on, heat 32deg, fill engine with demineralised water (can I skip opening the bleeder valve here?)

4. Run up to temp.

5. Let car cool.

6. Repeat 1-3.

7. Open bleeder valve, fill up with coolant mixture, finish as per workshop manual.

Would this work OK to flush the old coolant out? I've read a few different procedures on here but just wondering if this would work.

Cheers!

Easy. Drain coolant from radiator. Remove radiator hoses, put your garden hose in the port for the radiator hose on the block and blast water thrrough the block, put everything back together. Run some coolant through it and get temp up past your thermostat opening temp, let it circulate. Drain that if you want then put your fresh coolant in

Or something like that

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!  
    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
