Alternative to G12 Coolant????

[Umai Naa!!]

Repco currently has the Penrite 5 Year pink coolant on sale for $37 for the 5L concentrate.

Worth noting, that Penrite apparently has G12++ approval from Volkswagen for their pink '5 Year' coolant. Can be bought pre-mixed, or as a concentrate.

Penrite's coolant is approved for G12 and G12+, but not G12++ nor G13.

EDIT: looks like their new product is now approved for G12, G12+ and G12++.

Good news - Diesel_vert can be impressed again, now

I've been using it for a while now.

Seems like good stuff.

Just be careful when using it. The Penrite says "complete flush required" , so based on this, I would stick with the genuine coolant. In which case I can only drain, flush it once if needed and fill up with the original again.

Haha, I am.

I think Penrite recommend flushing the cooling system simply as a statement of best practice - and a good idea a that - even if the vehicle manufacturer doesn't specify a change interval.

I don't think it's a deliberate or strictly required instruction (though if one goes to the trouble of draining the coolant, surely it would be logical to flush the system while you're at it), nor is it a hidden inference that their product might not be incompatible with genuine coolant (which I don't think it is).

So I would use their product with full confidence - even for top ups.

However, a pressurised cooling system that needs topping up would indicate something is amiss, and would warrant further investigation - but that's for another day.

I would never mix 2 different brands of coolant, but hey it's your car .

Yeah, absolutely.

Although coincidently, I've had no choice as previous workshops had foolishly put green stuff in. One even had a mixture of both...

Certainly, that's a good rule of thumb and I understand where you're coming from - particularly if compatibility is not a known quantity.

However, in this case, Penrite has taken the trouble of obtaining certification and approval from VW (I doubt there is much leeway or flexibility in the way of chemical composition and additives), making it highly likely that their product will be compatible with the genuine coolant.

As is the case with engine oils, VW doesn't care what brand you use - just that whatever product you use conforms with their standards and specifications.

To that end, a manufacturer going through VW's certification and approval process makes it easier for the consumer to choose appropriate products with confidence.
