Hi all,

I have just purchased a new 300tdi discovery as my old one was getting abit to ropey. Now I'm not sure if it's because this one is just a darn sight better or if there is a problem.

My disco seems to heat up to almost full temp at about 2miles of driving. It supposedly had a new head gasket and skim two years ago. The other thing I have noticed is that the top hose is nice and warm and the bottom one is nice and hot as well but more so towards the top of it. (Hope that makes sense) but not a equal temperature all the way along its length nearer the rad is cooler but still warm. As for the radiator core it's self it's what I would say as cool not hot at all. Is this normal as my heater is lovely and warm and throws out plenty of heat.

Forgot to add that the expansion tank seems to be pressurising but the coolant is piping hot as to be expected. After doing 60 mile in her yesterday I went out and checked on the coolant today and the expansion tank was still holding pressure.It doesn't appear to be using any coolant either. I have completed a 150 mile trip no probs today so maybe I'm just over reacting.
Look forward to hearing your opinions.

Many thanks
Kyle
 
Can't help with specifics, plus I've got a TD5 not a 300... HOWEVER...

I have a daily commute to work of just over 5 miles. Temperature up to half i.e. where it should be on the gauge after about 3 miles. Heater blowing out hot air before then ;)

OK -engine generates heat which the cooling system takes away - your heater is lovely and warm - the engine heat is being delivered to you via the heater matrix leaving the radiator with not too much work to do until everything gets up to temperature so I'd guess that's normal.
 
Got about a six mile drive to work the temp gauge tends to sit just above quarter of the way. heater is nice and warm but haven't really used it much since I've had the car
 
I have a '96 300tdi. It takes roughly 40mile to warm up, because i have taken the thermostat out, so the coolant is going all the time.

It is ok, but on a cold morning, i spend most of the way to work freezing me tits off.
 
Your telling me, cold damp mornings at 4am. Driving to work freezing and dreaming of bed isn't much fun.

But it does seem to be that after the first run, it warms up a bit quicker until the next day.
