Hey,

Going to change my coolant and flush out the coolant system tomorrow and was wondering what is the best coolant to get? And how much of it will I need? Do you recommend 50/50 water mixture as well?

Thanks,
Chris.

Advice give by beaker and monka is spot it, its the best by far :)

2 litres and the rest water, make sure you bleed the air out, have the heating on full blast and make sure the fan kicks in before you drive it

^Don't think that is right mate. The Toyota coolant comes pre mixed, and there isn't any need idle until you're up to temperature.

Also, the starlet is a self bleeding system, so you just ensure the overflow bottle is full and use the car as normal, topping up the overflow as necessary (after you fill the radiator to the top of course!)

As the system pressurises and depressurises (heat and cool cycle) it'll naturally work the air out.

Most, but not all, you'll have plenty left to topup at a later date should you need to :)

3.5L is in my mind for some reason though, but that might be the oil volume with an oil filter change lol...

Hmm...from doing oil changes I'm pretty sure thats oil! But if I buy a 5L bottle I'm sure thatll be enough! Cheers for the help Dave!

Yea, the big one (5L I'm sure) is more than enough, the smaller one (1L) is nowhere near enough :p

Anytime mate

Job done. Had it running for ages and ages, took it out for a good blast (or 3) and temp gauge now sits below the symbol whereas before it used to sit above! Think I didn't have it right full before, and now it is! At toyota the guy said they've bought out an additional Pink coloured for life; change at intervals of 100,000 instead of 60,000 lol :s

I used some coolant that changes colour on gasket failure its called 4 Life but its NOT the toyota one. It's also pre mixed but I added some distilled water into mine.

I used this, a little water wetter and some normal distilled battery water to increase heat transfer properties.

My GTti was sitting at 2/3'rds at a sustained 65/70mph.

Used to sit just under half at those speeds on motorway driving - amazing difference.

The toyota For life is similar, going on what I've read. Comes pre-mixed and turns yellow if contaminated with oil etc. 5Litres of the Toyota stuff came in at 17.99 from Toyota themselves, so not a huge saving with that 4 Life stuffs! I didn't add any water, just used the mixture itself. To be fair, the coolant in there was clean as a whistle - we filtered it and my dad wants to take it to toyota to get it tested lol. But yeah, colour wise it was identical to the new stuff which isn't surprising seeing as it had a rebuilt in 2006 so must've been changed then!
