What Brand Coolant Do You Use?

[allsleepnorice]

First, I have a search impediment. Deal with it.

HI, I have an RB25DET with a new alloy radiator and am wondering which coolant to use? The car came with an alloy radiator but it got corroded and turned to shit. It had green coolant, but not sure what brand. Ive previously had bad experiences with Tectaloy, so Im thinking (hoping) they used that.

Has anyone used anything like Waterwetter? Can we get products similar to that in oz?

Has anyone used red coolant in an RB?

Cheers

Nissan L250 is what you need. Or a coolant which has this specification. Old japanese cars have a P-OAT coolant. It's always green. Mazda FL22 is the same and Honda E Coolant too.

If you don't flush out the old coolant, it will react with the new coolant you use, starting by making your new alloy radiator blacken within a few days.

Nissan service centre / dealership at around $60 for a 5L bottle.

I use pre-mixed Tectaloy in 3 of my Skylines without issue. The GTR for a decade.

Both stock and alli radiators. R32 GTR, R32 4 Door, R34 GTT and a Liberty

If you have had an issue it was already corroded, or you have mixed red/green coolant without a proper flush.

If you add water make sure it's distilled as mentioned above.

I have seen different brands of green coolant do the same thing. Flushing the block until it runs clear, or 5-6 times is the only way to be sure.

I have always used tank water without issue, the local Natrad bloke swears by normal tap water. We both agree it's the mixing of brands that causes the corrosion, not the water quality.

The best option is Evans coolant. No boiling, no corrosion and no expansion by removing water from the equation altogether.

Ive used Nulon long life and deionised water for the past 6 years. No hassles.

How fresh did the coolant look when you first checked it? The main ingredient Ethylene Glycol in coolant starts to turn acidic from heat over time.

Just keep in mind the possibility of stray electrical current (Electrolysis) within the cooling system which can Eat away at your radiator.

Fancy name coolants still will not stop this.

Using Nulon LLC premixed coolant. Got it on sale bargain!

Is this more a problem with aftermarket alloy radiators.?
