I'm preparing to do a coolant change and I've got a UView vacuum system to refill the system. This means that I must have adequate coolant in a single container to completely fill the system before I start since it will be drawn in under vacuum all at once. I bought 4 qts of Honda coolant but the service manual shows the capacity of the system as 4.07 qts. Does this include the overflow bottle or should I buy another quart so that I have 5 qts to draw from?

When you drain the coolant, you won't get every ounce of it out. I bought a gallon of 50/50 premix and filled the system by pouring it in, allowing air to bubble out along the way. I also put some in the overflow tank. I did not use the whole gallon.

I didn't use a whole gallon either, but then again, I didn't use a UView.

FWIW, the radiators and engine together hold 3.73 quarts; the reserve tank holds 0.69 quarts.

Usually a simple drain and fill will take either just under or just over 4 qts so always have 5 on hand. With your method, it will probably take more then 4. Yes, that includes filling an empty resevior after it was removed and cleaned.

Buy the extra coolant. The last thing you want is to get so low in your container as to introduce air into the system. Better to have a "safety" margin with the extra coolant so that the syphon tube is without question completely submerged the entire time. Also remember that the tubing of the Uview takes some capacity (although small).

Just save yourself the headache and buy an extra gallon.

Dip your finger in the new coolant to the first knucle, shake off the excess. Thats your 7/100th of an oz of coolant

Not being cheap or anything but for .07 can't make up the difference in the 50-50 with water making it 49.14-50.86. More likely you never that that last .07 out of the system and hoses.

I used a bit less than a gallon. I just drained and refilled. A simple job.
