Funnel: This may sound simple but its a tool that your tool person will have. My techs have really found this useful anytime the cooling system needs to be filled. It connects to the radiator neck and allows you to do other things without standing by to watch it bleed. It also saves the mess once it blurbs the air pockets.Its a must have for the headgasket update.
I really need your help telling me what you have found that works when you repair Toyota's. Let me know so we can share the information. email@example.com
