kilgore Posted August 31, 2008 Share Posted August 31, 2008 Hi, changed the radiator and coolant the other day in my EA82. When we opened the second block plug (the one located above the crossmember) no coolant came out. Flushed it out with a garden hose and it wasn't draining here either. She only took 3 litres of coolant as well and is not running hot. Sounds plugged somewhere to me. Any recommendations? Thanks. Quote Link to comment Share on other sites More sharing options...
NorthWet Posted September 1, 2008 Share Posted September 1, 2008 By the block plug, are you referring to the one on the bottom of the non-distributor side of the engine, parallel to the ground? I would be very concerned if nothing came out of that one. That side of the engine is fed by a "transom" passage high on the block near the waterpump. (The little hose that runs from the top of the block to the t-stat housing hooks in to that passage.) I suspect that if the coolant isn't high enough to reach that passage then the waterpump doesn't send much, if any, coolant to that side; but there still should be SOMETHING above that plug.

TomRhere Posted September 1, 2008 Share Posted September 1, 2008 I'll bet there's a plug of sediment blocking that drain hole. Not to many people mess with that one 'cause of where it's located, kinda difficult to get to. I've had 2 engines with the drain in the PS head blocked with sediment, and had to open it up with a small screwdriver. The end of a coat hanger may be the proper tool for that drain hole.

The Dude Abides Posted September 17, 2010 Share Posted September 17, 2010 To bring up an old thread. How important is it to drain those block plugs if your flushing the coolant. Quote Link to comment Share on other sites More sharing options...
TomRhere Posted September 18, 2010 Share Posted September 18, 2010 Those drain plugs are the only way to fully empty the engine of coolant. Quote Link to comment Share on other sites More sharing options...
Duraznov Posted September 19, 2010 Share Posted September 19, 2010 I have the same problem, but it looks like the drain plug is broken and a part of it remains on its place, since the screwdriver I put into the hole seems to ends up knocking something very hard and impossible to remove Quote Link to comment Share on other sites More sharing options...
