The coolant travels from the radiator to the engine through hoses, where it absorbs excess engine heat before returning to the radiator.įind wholesale g12 antifreeze coolant units to maintain temperature control for computers and electrical systems. With numerous repeated controlled gasoline explosions occurring every second to power your vehicle, it's simple to see why you need a robust cooling system to keep the automobile from overheating. So why not source a replacement instantly via our g12 antifreeze coolant store? The same applies to mirror covers, headlights and side panels. For instance, it's easy to damage bumpers or tail fins during ordinary driving. The best way to check the concentration is to check the specific gravity of the coolant (which is what a decent garage do with a hydrometer)įor what it costs, always use Genuine VAG G12++.If you're working on your own vehicle, the auto parts collection at has what you need. It is not recommended to exceed 50% concentration as the cooling properties suffer. Note that UK spec Skodas are supplied with 30% concentration coolant - the minimum necessary to provide long term corrosion protection. Its the deadly combination of G11 and the original G12 that's a disaster - it produces a gel that is almost impossible to remove from the engine block. If you have a car with G11 (pre 1999 IIRC) you CAN top up with G12 + or G12 ++. Most users will never need to top up if you follow this. And ALWAYS use premixed (30%-50% G12++ with boiled or distilled water) coolant to top up to no more than the MIN mark - the MAX mark is where the coolant will be with a hot engine. Moral - unless its more than 15mm below the MIN mark - leave it alone. A lot of owners are likely to top up with plain water (which has a lot of dissolved air in it) or any old brand antifreeze as part of their weekly or monthly level check ritual - what happens is the coolant is diluted or contaminated over a period of a couple of years with regular input of dissolved fresh air and soon the corrosion/sludge starts. Instinct may say top it up to the MAX mark, but all that happens is the coolant expands when hot and is thrown out and settles back to the MIN mark. I have always found VAG cars settle with their coolant to just below the MIN mark (by up to 10mm) when cold. The problem is when they get diluted/contaminated by over enthusiastic owners. What you must not do under any circumstance is mix the Red coolant with a blue/green coolant as this is where a gunge type subtance is made after a while that coats everything in the cooling path of the car and isnt good.Īll VAG coolants since G11 have been "lifetime" coolants. Id say if you need to top up the coolant, then as long as its a red coolant of G12 spec then its safe to use altho its better to use G12+ as thats the recomendation. Now how this is possible I dont know, i can see it from the point of veiw, dont mix old spec with new spec but TL744F G12+ coolant is designed for use to be mixed safely with the old spec G12. Now this is the weird part, G12+ TL744F coolant CAN be used to top up a cooling system filled with G12 TL744D. Now this is the confusing part, it is not recomended to top up a cooling system filled with G12+ TL744F with G12 TL744D due to possible reaction, only plain/deionised water is recomended. Most long life coolants (red / orange) ive seen are TL744D which is the old spec (engine made before 2000 i think).
Apparently the correct spec is G12+ TL744F for VAG engines.
