My TDi 300 (160,000km) Thermostat Housing Bung (Black Plastic Bung) had sheared off and looked pretty much melted.

Get rid of those plastic plugs and replace them with brass or bronze. From what I remember there is one in the radiator as well. Any mechanic with experience with rovers should know this.[/b][/quote]

The funny thing is that they replaced the old Bung with a Brass one, which leaked a little, and I asked them to toghten it up, and they replaced it with a Genuine Plastic Bung, and then the trouble started

Hi Thermostats in the 300 tdi are rubbish in hot conditions what you need to do is cut the centre out of the thermostat , just leaving the outer ring for the rubber seal.
VERY IMPORTANT you need to insert something like what's in the picture below ( from v8 clutch fork assembly ) into the water hose that is at the top of the engine from the thermostat housing that arches over and goes to the water pump ( this water pipe is required for rapid warm up of the engine if a thermostat is fitted, not required if thermostat has been removed) once the engine is warn the thermostat cuts the flow through this pipe anyway.
You will no longer have overheating problems on your 300 tdi.
this procedure has been tried and tested very successfully in all our safari hire vehicles in Africa.
We hardly get any overheating engines now, after years of expensive head/engine replacements.
We also carry out this procedure to vehicles we prep to travel through Africa.
and do what everyone else is saying " get rid of the plastic bungs"
If anyone needs more info on this please let me know https://www.aulro.com/afvb/*

Hi Merlin - I live at Balhannah growing grapes. Where are you?

I had 1 service done by Black Forest Land Rover, for which they tried to charge me $650. I told them to shove it and we eventually agreed on $400. Never need to go back there luckily.

Since then I have always gone to Soverign Motors (down in Adelaide). They use genuine parts and have an ex-UK Land Rover mechanic who is excellent. Would highly recommend them.

Unfortunately that was still on your local disk.

You need to upload it to a website somewhere and link to it. Can be any website, even this one! Just create a gallery and link to it there.

Else send it to me via email and I'll put it up for you.

Cheers,


Glenn.

kie4 does this mod work with the TD5. Had the pressure test done on mine today and it seemed fine 8) . Tomorrow I will be having the chemical test of the coolant (Currently water) done. If my head is ok I am talking to a local garrage about the cost of building a custom thermostat housing to accept the common ford/holden ones so I can change it at will. We are also looking into the work involved with replacing the hoses with metal ones with small rubber joiner bits.
