Sumo Posted March 18, 2003 Share Posted March 18, 2003 I just use Caltex radiator coolant.... Its supposed to be a 50/50 mix. Flush your radiator, e.g. drop all your water out (undo the bottom hose on the radiator.... I think I undid the one going to the motor as it was easier then pushed the hose down to the ground). Put the hose back on fill it up with clean water (and radiator cleaner if need be) and start your car so it runs through and turn your heater on.then once its been running long enough pull that hose off and drop that water out.... once you have done that fill up with fresh coolant and water (premix it @ 50/50 or what ever the bottle says) and you will be sure that you have flushed it. Cheers Sumo P.S. Let your engine/radiator cool down before you put cold water in it as it may cause things to crack (expanding and contracting too quickly) Link to comment https://www.sau.com.au/forums/topic/12332-flushing-radiator/#findComment-223340 Share on other sites More sharing options...

crooser Posted April 7, 2003 Share Posted April 7, 2003 Dont forget to bleed out any air when filling it back up. Its the little screw just in front of the plenum. Its important to do this as quite a bit of air can be trapped in there.

JimX Posted April 8, 2003 Share Posted April 8, 2003 How do you bleed the radiator? I know where the bleeder is, but dunno how to do it exactly. Do you just fill up the radiator and leave the bleeder open until all the air bubbles escape then close it again? Also how long does the water pump usually last? I'm just wondering if I should change it at the same time as I do a coolant flush with my upcoming 100k km service.

crooser Posted April 9, 2003 Share Posted April 9, 2003 Not sure of the correct way but i just filled the radiator - then with the car idleing, unscrew the bleeder right out. it will bubble and carry on for a couple of mins. keep topping up the the radiator in the process. carefull if the car is hot because the bleeder tends to spit a bit. hope this helps some Link to comment https://www.sau.com.au/forums/topic/12332-flushing-radiator/#findComment-268151 Share on other sites More sharing options...
Brody Posted September 12, 2003 Share Posted September 12, 2003 Hate to bring up such an old thread, though wtf is the bleeder on a 32?!!? ive just flsuhed out mine, all seems to be ok, though don't want to have risks...i looked everywhere for anything that may be it but no luck... Only thing i could see was a nut ontop and says 'never open when hot'.. any quick answers would be great as its friday nite ;p Link to comment https://www.sau.com.au/forums/topic/12332-flushing-radiator/#findComment-526562 Share on other sites More sharing options...
JimX Posted September 12, 2003 Share Posted September 12, 2003 The nut would be it. I take it it's attached to the plenum kind of near the front of the engine? Not sure if you have to take it out completely or not to bleed the system, but I did.

wrxhoon Posted September 12, 2003 Share Posted September 12, 2003 if u use 33% usualy 3 years i do mine every 2 years on all my cars and its always very clean . when i let the old one out i flash the system , undo the bottom of the radiator and the screw on the engine block so it lets all of the old coolant out flash it with clean water blow all water out then fill it up again .

silverskyline Posted September 15, 2003 Share Posted September 15, 2003 SKYLINE_PAUL, u say ur water is gone muddy, i had this problem b4, firstly the best coolant to by is just nissan coolant, when u flush ur radiator outby something that kills rust, the reason why ure water is so muddy is because u had to much water not enough coolant, after u have the new coolant in make sure u check the car over the several days because u may get a few leaks , mainly the water pump, and also keep checking the under the cap over the next few weeks to see if it stays green, i had to do about 3 flushes b4 i got the nice green colour back, urn cooling system is the most important thing on ur car, Link to comment https://www.sau.com.au/forums/topic/12332-flushing-radiator/#findComment-530254 Share on other sites More sharing options...
wrxhoon Posted September 16, 2003 Share Posted September 16, 2003 the reason ur water is muddy is because at some stage before it had just water in it or the coolant was very old and infective , common with jap imports as they are not serviced in japan . give it a good flush and use a good coolant ready mixed dont add any water to it . u can use any coolant as long as it is at least 33% and change it every 2 years .

Anquetil Posted September 19, 2003 Share Posted September 19, 2003 Guys, how many litres of coolant will be needed do you think? I've got 5 litres of 60 Plus (2 Years) coolant, and it says not to mix with other coolant or water. I just dont want to get half way through the job and realise I need more and be sorta stuck with an undriveable car?

wrxhoon Posted September 20, 2003 Share Posted September 20, 2003 if u get all the old coolant out u need about 8 lts . i'll give u a tip dont buy 60+ again , buy any brand u want as long as it has a min of 33% ethylene glycol .
