Cool. It also helps if you park the car on ramps or an incline so any trapped air will be forced up and out of the bleed port. Once the engine reaches operating temperature, you should feel the radiator hoses pressurize and perhaps you might be able to feel if coolant is flowing through it. This will help you determine if your water pump is functioning. Although I've never tried it, it's been recommended to me to use a product called "Water Wetter" by Redline. It's supposed to lower the surface tension of the coolant/water allowing it to circulate better and relieve itself of air bubbles easier. edit; this may seem like a dumb question, but when you say "put car to ON", you mean the engine is running correct? Obviously the engine needs to be running to spin the water pump, otherwise coolant won't circulate. Last edited by cooljess76; 10-26-2012 at 09:48 AM. |
