This one from Parts 4 Engines .......... £10 Equivalent to Yanmar part number 129673-44131 Yanmar 3JH and 4JH Series Header tank cap .

If you connect a hose to the water tube you should get good flow from the tell tale. If not maybe the telltale is blocked. Try probing with a wire. If still no joy you will have to investigate You may not get a flow through the engine while the thermostat is shut, I'm not sure about that with...

Check power is being applied when key is in heat position........... If power is being applied test the heater plugs.... they have a low resistance I always tested in diesel cars, when I had such with my 12 volt test lamp. Battery +ve to each glow plug in turn . Lamp should light if plug OK...

Oxalic acid crystals are readily available eg from AG Woodcare or various ebay sources. Use a near saturated solution ( 5% will not be very effective). Does not work well at low ambient temperatures though. .

You dont say where these stains are. Y10 is the well known product for removing waterline stains. It contains oxalic acid. A solution of oxalic acid, thickened with wallpaper paste if necessary, can be used on the decks or elsewhere. Oxalic acid is particularly useful for removing rust...

They are often marked with the pressure , either in bar or in psi or both but ITYWF you will also have to match the length..

I have an old car car headlamp bulb on a couple of leads (even has spade terminals so soldering was not necessary) Doubles as a 12 volt "lead lamp" From the pre halogen and sealed beam era. I think it came out of my father's first car.

Thanks for the feed back. .

Early versions with an isolated electrical system have two fuse blocks as described in the text, one in the positive and one in the negative, but it is irrelevant to the thread because the OP has stated that he has the D version ( I had not noticed that) The second snip is the relevant one and...

Galvanised would be the best choice ( Nigel Warren PBO February 1988) Otherwise 316 stainless steel and Duralac .

It certainly wont be charging the battery at 12.5 volts. You are just seeing battery volts, it's not generating Id expect 14 to 14.4 volts. Check the wiring against the schematic in the owners manual in particular the blue/black wire on the L terminal which is the warning light connection...

Early engines with an isolated electrical system have two fuse blocks B versions onwards have just one fuse block

Dodgy key switch perhaps. Its not good enough just to make sure connections are tight. they must be clean and tight Clean and remake all the battery cable connections and the battery terminal clamps including the isolator switch connections and the earth connections. Also the power from the...

The alternator wiring on the MD2030A is different in so much as there is no separate excitation supply like there is on later versions ( BL/R wire)

The GN/R wire from the glow plug relay should go to the nearby multipin connector. .
