Ok, lets say I want to change the coolant. I have had only fords till now. The ford uses the additive to prevent cavitation. I hear the ctd is sleeveless. This would lead me to believe I need no additive, but would it hurt if I have a case sitting around to use it. Better yet, would it help anything? Also, you guys recommend some coolant brands and how much it will hold, ease of job, how to get the thing filled back up without having to add a little here and there forever.

 

I use the Fleetguard 50/50 premix, mainly cause I'm too lazy to mess with mixing the others. ;D<br><br>DB
