EH700 Manicooler and Engine Drain Points

[HughfromOz]

I have never had to drain the coolant from the manicooler or the block, but it looks like I have to do it from now on. Could you show me where these are??

The manicooler drain is at the bottom, aft end of the manicooler. If it hasn't been opened in a while perhaps some penetrationg oil first. The block drain is on the aft end of the engine, port side in front of the starter. Banjo bolt and a drain hose coming off of it to the bilge. I believe a 14 or 17 mm box end wrench for it. To drain the coolant from the water heater and cabin heater I remove the upper hose from the engine and use a gentle stream of air (compressor or just blow on the end). This blows the coolant into the block and out the aft drain.

It’s 14 mm. I change oil & transmission fluids by using the oil pump on the 5 gal.bucket and the vacuum pump to drain the block and water tank.
