Club 80-90 Forums

Hi,

I've been running my AAZ now for 12months with no issues at all except that it tends to run quite hot. I know about turbo diesels running hotter than petrols due to the oil cooling etc but this is the issue with mine:

Start engine and after 20 mins or so the temp gauge steadily climbs to just over half way (needle thickness past half way) - is this correct?

If i drive the van around (even in cold weather) the gauge climbs approx another needle thickness past the first tick-over point. The needle will stay at this point for any distance.

However, if i sit on the motorway at 80mph or climb a long hill, the needle will climb right up to the max but no light comes on. The needle will sit in this position untill either i slow down or the hill levels out. Is this normal??

I've been running it now for 12mnths, last week i bled the system but no air came out.

I've got a trip in the summer to the SW France and am a little worried of overheating.

Any advice - or is this normal and i should go and buy a nice shiny oil cooler kit from BAxter? (oil temp was 127deg at MOT).

Cheers!

If this is not normal i will start with flushing ect.

Sounds completely normal to me - driving around at 80 will do that.

I have a oil cooler fitted (fitted it on day one) and on very steep long runs the temp still goes up a little (happened once in the lake district). However, the oil cooler does give me confidence so i dont worry about it.....

Get an oil cooler fitted....

Just fitted and oil temperature gauge to my van (AAZ none external oil cooled) and it read 130*C....

Guess i could retro fit an external cooler from a later A6 or something like that, the sandwich plates are plentyful on e-bay and get Pirtec to make up the hoses, can't see why should pay £00's for kits...

Anyone retro fitted a cooler? can't be rocket science.

Oil temp will typically be 10-20 deg above coolant, even on a modern Tdi car - which will have an oil cooler fitted as standard and that's up front getting proper air flow...
So when pushing it to 80 mph, coolant at 90-100, oil at 110-120. Sounds ok to me.

I'll up-grade the oil and it can stay as it is then!!
