I am about to change my coolant. Should I use Ford's coolant or the premixed stuff or any coolant will do? Also, what would be the capacity on a 4.6 without a towing package? How many jugs do I but? Thanks.

 

Sorry. I meant "do I buy" not but. Thanks.

 

Me thinks any coolant would do as long as it's not that recycled stuff. If you change it when the manual states you should be fine.....

 

Dont waste your time on the pre-mixed stuff. Why pay full price for half as much anti-freeze. You surely don't need to buy the Motorcraft brand from the dealer. Just go to wally world and get some Prestone.

 

If it came with the green stuff, put green back in.
If it came with the yellow stuff, put yellow back in.
If it came with the orange stuff, put orange back in.

Don't mix the type of coolant.
And definitely don't put the orange long life in as a replacement for
the green stuff.

Capacities are in your owners manual. Some cooling systems
require vacuum filling or special care in bleeding out air.
Consult a service manual for specifics.

Stick with name brand coolants like prestone or motorcraft.

Make sure you mix 50/50. Never use straight glycol.
Heat txfer properties are adversely affected and you can
get engine damage.

I agree somewhat.

Don't mix them...I agree...don't change to a different one...I disagree.

If you want to change antifreeze every year, by all means use green. Pink has no place in an auto...made for RV's.
Orange is an accepable replacement for green, but make sure to completely flush your system of green before switching..I will run 3 full flushes with water and one with chemical before switching. Now you have 5 years between changing instead of one.

Oh, by the way, the reason you change green anti-freeze every year is it will turn acidic and eat away your cooling system.

The reason you change Orange coolant is to expell rust from the system.

Now, going on to yellow, ten years! Why, except cost wouldn't you use this stuff? It prevents corrosion including rust. The reason you change this stuff at all is just preventative maintance. When flushing, your checking the cooling system. The fluid is actually still good. If you won't keep your vehicle for ten years, don't waste your money.
