what you have now is that the inlet water is not being shut off correctly and the water is still coming in and flowing out of the overflow

Make sure all the drains are closed, start filling the rad and allow the coolant time to drain down, then fill again. Keep filling the rad unit it no longer drains down, just make sure to stop filling it when the level in the rad is just barely visible when looking down inside it. Now fill the overflow bottle to the lowest level mark. Start the car and turn you heater on to full heat. Let it warm up to proper temp, may/may not need to put more in rad. Keep an eye on the level in the rad it will expand and may overflow, if it looks like it will overflow use yout tester to remove some fluid. Once you see the coolant flowing throug the rad wait a few minutes, then put the rad cap on. Let it run a few more minutes to get the rest of the air out, then drive like normal. Check the fluid level in the overflow bottle (engine cold) over the next few days fill to proper level as needed.

Generally now there is a plastic overflow tank, where you do this, and not into the radiator top neck. The cap there is usually not meant to be routinely removed. There will be a hose about 1/2" diameter from the side of the radiator top neck to the overflow/filler tank. Just follow that.

If you manually pull up on the float of the fill valve will it then shut off? If it does, most likely your water pressure is too high, should be around 60 psi. More then 80 and it won't shut off. You may need to add a restrictor to the fill valve. Most fluid-master units come with one already installed, you could try one of them.

take rad cap off when cooled down. overflow resevoir is just for that, overflow of antifreeze

On that particular vehicle there is no dipstick. There is a fill plug and an overflow plug on the transmission itself. To fill the transmission, you must use the Toyota manufacturer's automatic transmission fluid and have the vehicle on a flat, level surface. Remove the overflow plug and place a drain pan under it to catch any excess that runs out. Remove the fill plug, and fill the transmission with approved fluid until it begins to run out of the overflow hole. Wait until the excess has finished draining out, then reinstall the overflow and fill plugs and you're all set.

Is the drip comming from the small fill tube going into the overflow? If so you may need to raise it a little. The nost common leak is from the flapper or seal. On rare occasioms the flush valve itself has a defect that will cause it to leak. Take a close look at the problem and Im sure you will find it. I hope this helps.

Check tank for fill line running from fill valve to overflow tube. It will be a 1/4 " line that allows the tank and bowl to fill. It should be connected from fill valve and connected at the top of overflow by a clip or hanger.

Check out the water level in tank to make sure it is filling to line on overflow or within 5/8" to top of overflow pipe.

Check the fill line in the tank and make sure it is connected from fill valve to overflow tube. After you flush the toilet it fill's the bowl and tank.

It should be a line about 1/4 ' in size coming from fill valve to overflow tube.
