The expansion tank area of mine is currently completely full with no air, I think this is normal. Mine has been recently bled as a result of changing (yet another leaky) plastic breather - just get to operating temp and let the air out gently and repeat as necessary is what I did.
I thought the expansion tank had a line on it to indicate the cold fill level?Quote:

Mine has water level in the tank at the cold fill line and the top area under the screw is completely full. I think it is normally like this but confess that I don't look at the top area often.
I have two bits of gear mounted above my steering column, a "Scangauge" and an "Engine Watchdog".
The Scanguage is set to Temp and Volts etc, the temp as far as I can tell is internal engine temperature from some sensor, it is very reactive when towing 3 ton van with outside temp around 30-9 it will climb to 104-6 towing uphill and within 5 minuts be back to 95-9 on the other side.
The Engine Watchdog gives me coolant tenp from the radiator as its returned to the engine and Automatic Transmission temp from the gearbox, both sensors are clamped on, the coolant to the top radiator hose and the gearbox one, to the pipe going from the gearbox to the oil coolers as close to the gearbox as I could get it.
Temp of coolact being returned to rhe engine is generally 20 to 30 degrees below internal engine reading.
Temp of auto when towing is around 86 to 96 degrees.
MR Auto sells and installs engine watchdog.

Good to know.I ran my Nannycom in instrument mode in the D2 to monitor real temps.
Something to add to the touring list.

I have noticed on very hot days the engine fan is quite loud,it also knocks the edge off performance.I wonder if they reduce output in hot weather.Talking 38degC plus days.Wouldnt surprise me.

Sorry, don't have any useful information on the fitting used. It was a last minute rush job as we were going away on holidays. A local industrial hose fitting place found a suitable part and fitted it for cash in a couple of minutes.:angel:Quote:
