Only a qualified service tech should replace coolant fluid. I've serviced TV's for a good while, and I would not attempt this repair without a co-worker showing me precisely what to do. You have to remove the Picture Tube(s) to do this, and if they leak after assembly, your TV circuit boards could be totalled out. The coolant is similar to anti-freeze and is corrosive.

How much transmission fluid does it take when changing the transmisssion screen and filter?

When the pan is dropped and fluid is drained, to refill, it usually needs 5 - 6 quarts. When refilling, check the transmission fluid dipstick as you are adding the last two quarts. And also run the transmission thru the gears.

My 60inc phillips magnovox has poor color, what do i have to do?

we just bought a 55 inch phillips magnavox and told it was working fine when we got it home and turned it on it was a red screen and was really foggy. we looked up some tv repair places and ONLY 1 told us it was the picture tube and to look down them with a flashlight for bacteria! sure enough the green and blue had it. so we found one place that would sell us the coolant fluid that you have to change the others could get it in or wanted us to bring the tv to them. we did it our selves the stuff was $17.00 a bottle or if we took it in it would be about $375.00. we have a great picture now and it wasn't as hard as all the other repair places said.

Have 115,000 miles on car ..when for an oil change and was told I needed to change transmission fluid and power steering fluid....Cannot locate my manual...when do these fluids need to be changed and is...

Regarding the transmission, if you have an automatic, use genuine Honda ATF fluid only and only do a drain and refill. A power flush will damage the Honda Transmission. It should be drained and refilled every 60k initially, then every 30k afterwards.
