The coolant needs to be changed on my 2001 Mustang Cobra. The manual calls for standard green coolant and specifically warns against using the orange extended life coolant (which would have been G-05, I believe). The engine currently has green coolant installed. I assume the warning against extended life coolant is really just a warning concerning the mixing of coolants, i.e. adding G-05 to a system containing green. However, I’m not sure.
I currently use green in a ’65 Mustang, G-05 in a Jeep, and have converted my Sierra to G-05 as well. I’d rather not add a third coolant to my inventory. Therefore, green or G-05 is going in the SVT Cobra. I would like to convert to G-05 so I don’t need to change it as often, but am willing to use green if G-05 presents a problem. Does anyone know if there is a fundamental compatibility problem using G-05 in the SVT, or is it simply that green was originally used and it shouldn’t be mixed with other coolants?
