Which radiator coolant to use? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I have been using that red coolant which I think ford dealerships used to use, but recently my car almost overheated and I found the red coolant had turned into a white foam.. I have heard that this red stuff corrodes gaskets, is this true? Could someone reccomend a type of coolant to use for my EL ? Thanks

I reckon you should use only genuine motorcraft coolant in EA-ED (blue) and then EF-EL (green) but actually looks pink.

The coolant will change colour if and when when it's overheated.
I know with the blue stuff, it puts a coating over all the internals where the coolant flows, to protect from corrosion.

The thermostat housing is designed to corrode (weaker alloy) so the head wont corrode as quick. As far as coolant corroding gaskets..... it shouldnt, the only thing you will see is the pink dye coming out through the hoses, thats why most of the ef/el's you see seem to have pink writing on the hoses.

Fords sell two types of the EF/EL coolant, beware of which one you buy, the cheaper of the two is weaker, spend the extra $.

In my EB, i double the dose - 2 bottles of the blue and the rest distilled water. NEVER use tap water.

Well I recommend that you only use the Ford green coolant or Rechochem coolant (premix or concenrate, they make the coolant for Ford, Holden, Toyota Bla bla bla). The red coolant that Ford used was a mistake and a damn joke, it was piss weak. The blue stuff is not too much better, and is better suited older cars, even older than EA's!

It's worth the money you spend on this stuff green Ford stuff. I think the part number is R31/32 or R33 or something like that.

If you use a 50/50 antifreeze/water mix, that will up the boiling point of the coolant by a few degrees. Check your radiator cap too.

Hmm.. reckon I should flush out the Tectaloy 30+ in my '91 EA and replace it with something actually worth using? Mum had a great idea too go buy some cheap shit while I cleaned out the radiator.. It's so high quality it says "For pre-1978 cars only"

You have to be careful, there were tests done and found that some 'cheaper' additives are only colour dye....

I'd like to know what the best is as I want it. :-D

Those cheapo ones also arent recommended for alloy heads..hence the "pre-1978"

Although as somebody else pointed out...some are nothing more than coloured water!

green but looks pink? change colour? no offence but it comes pink in the bottle. if its green it comes green.

ok basically there are 3 different coolants for falcons;

R13C 500ml blue as used in EA-ED

R150 1L red/pink used in EF-EL (i would recommend not to use this if you have it flush it out properly and use R133)

R132/R133 1L/5L green use in EF onwards

be carefull with the ratio of coolant with the R133/R132 too higher concentrate will cause problems. use about 33% in 6cyl and 50% in V8s. use about two bottles with the blue and 1 bottle if you use red.

Tectalloy 90+ was recomended to me.

Independant test by Choice (and MTA or perhaps RAA) said the GMH factory coolant was the best. About 5 radiator guys told me the same thing when I was having some heating probs in my ute.

I now use 25% GMH coolant and demin water after a demin flush or three was done. The way I look at it, if the HNxxxx part number is the best then thats what I'll use.
(Its actually made by Orica/ICI)
