Mixing Coolant

[del mar 2]

Afternoon,

4 different cars all appear to use different coolant.
G40
GG40
G48
G05

If you were to mix them what is actually going to happen ?

I doubt the coolant is going to solidify in the engine / cooling system.

Just curious.

Thanks

Probably nothing, they'd all be designed to work with others.

Imagine the scenario, Garage A carries out a Service changes fluid with Product A. 6 months later, you top it up with Product B which you've had in your garage for 3 years or more. Next year you take it to Garage B for a pre-winter check and they use Product C.

Not sure, but a mate put pink in his Espirit and it ate the pump impeller apparently.

Always follow the manufacturers data or from a trusted source like Autodata.
If in doubt flush and put in new.
One of the cheapest jobs you can do on a vehicle.

Patience dear boy or use a vacuum refil kit and whoosh it's in and done.
Otherwise you could blow a head gasket.

Not the case, different antifreeze aren't all compatible. There's two problems. Mixing them can prevent their corrosion inhibitors and two, some gaskets aren't compatible with certain types of antifreeze. Ducati had to recall the first few thousand gen 2 Multistradas as they'd used the wrong antifreeze on the production line, it'd eaten into the head gaskets and was blowing them.

Can you put too big a percentage antifreeze in a car? Could you say put in 100% coolant? Not suggesting it, just asking.

There are some waterless coolants but they use water for a reason, it has the best heat transfer ability of any liquid apart from ammonia I think. A lot of these extra coolant additives that supposedly reduce engine temps just reduce the coolants temp as it can't take as much heat from the engine so the temp gauge reads less but the engine itself gets hotter.

I thought I'd be kind to the environment and use a glycol substitute antifreeze in the Vette and Mini last time round. Although they seem OK in the engine but anywhere I've got it on a zinc or yellow plated metal eg the starter case its caused white corrosion so I'll be going back to glycol next time.

bit of a minefield antifreeze and you can get suckered in to all those fancy sounding ones with various additives, I use the ford stuff on all the motors and in my opinion it's one of the best out there
