Have just replaced the head on my KB10 (1200 motor). It was badly corroded from the coolant can anyone give me an idea of what coolant they use ?? thanks

tectalloy i think it is, anti freeze antio boil.

But using cheaper one now to test radiator temps.

I use the genuine Nissan coolant. Not because of loyalty but because I was at the parts counter when I remembered that I had forgotten to buy some at Repco earlier that morning.

It doesn't really matter what one you get as long as you remember two important things.

1. Get a well known & reputable brand & read the label before buying.

2. NEVER, never-ever mix two different coolants as some of these will react in a very negative way with some others, & you usually don't know about any negative reaction untill it's too late & the damage is done. [coagulation, blocking the radiator]

If you do not know what's in the engine now & you want to top up, then dump the lot, flush it once or twice, then start from square one. Remember to flush the heater too.

I know that you are near a major parts outlet, so geting something suitable should not be hard, but get enough to have a little left over for top ups later on.
Keep the empty container somewhere visible to remind you next year you what you had used.

I learned all this from the literature at my local radiator specialist while waiting for him to finish a job for me one day.

Yep, use genuine coolant. Weather it be Nissan or Toyota etc. Toyota especialy has a good name. Pretty much anything red in colour.

We encountered a EL Falcon(netorious for cooling problems) with red Toyota coolant in it from a very early age. Not one spot of corrosion on it! Usualy for a Falcon of the same mileage every housing would be leaking and corroded, along with 1/2 the head!

So genuine coolants are the way to go!

yep thats the way to go lads i allways use tecytaloy if not tojo than factory &and you won't have any probs and as dodgeman [got it right this time]said DO NOT MIX FLUSH IT CLEAN happy cooling see ya.???how do i add icons to text i know dah huh but new at this???
