hey guys, just need to change the radiator fluid in my dads stateman for him, i learnt a bit about how to do it the other day thanks to Jayce and ed, i take it there is a plug i pull out to drain it? then i just mix the fluid and distilled water according to the bottles instructions, then top up the radiator, then turn the car on to get it flowing through, then top it up again?

any more info or anything i have wrong?

I dont see why you'd have to use the plug?? When we drained my radiator we just un plugged the hose, then just let it all run out, then once this is done, shuv the hose in the top, and let the water run threw the radiator, then push the hose back on (once u feel its clean, and all the waters drained out again), mix the fluid up, put it into the radiator, turn the car on, and leave the cap off the top, and wait for the car to reach opperating temp (there abouts) and check that the water is still right up the top of the raditor. Put the cap back on, and your set to go...

hope this helps!

sounds good! searched on calais turbo and got some decent advice, ive taken the major bottom radiator hose off let it drain, flushed it with water, and will re-connect it and re-fill it, basically exactly what you said.

Also.... dayne is right there... but you have to flush out the whole system. ie Radiator, block, heater box..

So disconnect the radiator hoes to drain it out, and also disconnect one of the heater hoeses.. Turn the heater knob to "HOT" if electrical find the heater tap in the heater hose line and manually hold it open... then stick to water hose up the heater hoses and radiator hoses and flush it out in every direction until the water is clear.

Hope you understand that... maybe :S

Any probs ... just let me know, im willing to help :rofl:

Have fun... oh yea... once you have flushed it...connect the hoses back up. mix the 100% coolant to a 3rd with water..

1part coolant 2part water :)

and fill it up...

leave the radiator cap off, turn the car on and let it heat up (get the air buybbles out) should be right when the coolant in the radiator is hot... Just stick your finger in there... (you should know how to do that part :D)

Goodluck

      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.

      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.
