I used an 19mm 8 point (1/2″ drive) socket (a 16 point would not do it, so be warned!), bought from your website reference (a very good firm for tooling). I had to use a torque wrench with an 18″ handle to shift it as it was so tight, but it came out OK in the end. It needed a 6″ extension bar to reach the plug head, and some courage to apply the force needed as it felt as if something was sure to break.
I ordered a proper drain cock fitting from the local Volvo Penta agent (£9.89 – part no. VOP861 824), but when it came, it had a 13mm diameter base, but the hole in the block was 26mm. So they ordered an adapter for me (£6.32 part no VOP 3850290, which did the job. I can now drain the coolant without flooding the bilge with the damned stuff, using a thin rubber tube in the cock outlet, and no other tooling needed.
Volvo are very naughty for supplying engines without the proper cock on as shown in the manual, as it makes changing the coolant difficult to the point where people don’t do it. Still, with enough patience, perseverence and money it can be altered as above. So take heart Volvo MD2030 -D owners, all is not lost. If you are ordering parts though, give the full engine details from the plate on the top of the engine, as different marks of the 2030 have subtel differences which can be important.May 4, 2009 at 6:29 pm #7719AnonymousI had the same problem so if any one in the Maldon or Walton on Naze area wants to remove the plug I have the tools to do it.
