MG MGF Technical - Coolant I know i know
|97 MGF has the green coolant in. Have been trawling the dieters and Rob's site to try and find out what I can top it up with but very little luck. OAT non OAT..arrghhhh|
Is there a brand in the UK I can just chuck straight in, or will it require a flush and brand new the lot?
I got some Havoline stuff from the dealers a while back which they said would be ok to use, but its pinky and set alarm bells off for mixing it with the current stuff I have.
|go back to the dealer and get some Xpart stuff, still green, but with a less excessive mix on the side (can go down to 1 in 5 IIRC rather than 1 in 2).|
Pink or blue is OAT and should not be mixed.
|There really isn't any magic here. Except that you musn't mix OAT stuff with other types, any antifreeze suitable for aluminium engines is OK. Read the bottle - if it's OAT it will tell you clearly. I have tended to use Halfords brand in my other cars, but it's blue so will look for something green/yellow for the F, otherwise the mixture ends up sludge coloured.|
|Right....so is the green stuff OAT or not????|
|Green is not. AFAIK!|
|Yup - I can confirm that, green is non-OAT. You've got the Unipart SuperPlus 3 in your car (it turns green in time).|
|OAT coolant is normally pink.|
|Is the green stuff ok then? What does OAT stand for?|
Why can't you mix them? Some kind of chemical reaction in your coolant system right where you don't want it?
|OAT = Organic Acid Technology|
|Yes I believe the green stuff is OK. I use it!|
Coolants containing OAT use organic acid salts to prevent metal corrosion. They have a longer life than IAT (inorganic) based coolants and are indicated as having a service life of 4-5 years/100,00-150,000 miles.
I don't think your car will blow up if you mix them, but it certainly is not advised to do so - due to the chemical differences in each product. I would imagine the extra corrosion protection and service life you gain from using an OAT coolant would be negated by using an IAT coolant.
|Thanks for your answers Fiona, the coolant in my car is green - I have only just got the car so that was what was in it. I guess it will have to do until I fit the B&G coolant level sensor kit, then I could flush the whole system I suppose and change it. |
I am pretty sure I won't though!!
