Yes
the red coolant is only used in some GM models. you can use green only if it specifies that it can be used in GM vehicles.
No, do not mix types or colors.
be sure to not mix the different colours(red&Green) they Aren't compatiable with each other.if in doubt drain then flush system then completely renew the coolant.
red coolant use the dexcool
Green or red
The main difference between red and green coolant is the additives. The red has extra anti rust inhibitors useful in certain engines.
red
If the Red Coolant meets the specifications required by you vehicle manufacture you can perform a coolant flush on you system before replacing with the new coolant type.
97's with the v8 4.0l take the "dexicool" coolant that's red....but at most part stores they have the universal coolant that u can mix with green or red coolant and it don't matter...don't ever put just regualr green coolant in it unless u feel like possibly paying thousands in future repairs(ive heard nightmares of stories of headgaskets failing when wrong coolant was used)
Green, red, pink, orange, or blue.
Check your owner's manual. It recommends Toyota brand longlife (red) coolant. Toyota coolant is 'similar' to GM's Dexcool (orange) but the chemical makeup is slightly different. Do NOT use standard (green) Ethylene Glycol coolant unless you completely drain and flush (at least twice) your cooling system. Cheers
extended life "red coolant' Tell the people at the parts store and they will get you the oem coolant (do not mix red and green)
