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

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
