Engine Block Coolant Drain Plugs

[rexlex]

Where are they?

How many here just do drain and fill?

Is it really necessary to do flush?

Why would you want to remove drain plugs when you can do a flush much better?

There are no engine block drain plugs. You may be thinking of freeze plugs which are not normally removed.

HOW DO YOU DO YOUR COOLANT FLUSHES ON YOUR RX300?

[SKperformance]

buy a prestone flush kit and do it yourself real easy.

I NEVER do coolant flushes absent a repair that requires it or the coolant degrades beyond the anti-freeze level I require (Seattle area) or if the Ph goes out of whack.

The only exception was that I changed out the factory coolant in my 1992 LS400 about two years ago, 11 years and 100,000 miles, simply because it was looking a little murky.

2 block drains. 1 near the oil filter. 1 near the timing belt tensioner. Both have a 17mm fitting with a 10mm drain petcock.
