Default Coolant level

I know this has probally been asked 1000 times but i thought i'd just ask to clear my mind.

I checked the coolant today and could'nt see through the side of the expansion tank so i removed to cap and i could see coolant up the the max mark printed on the inside of the tank, however when i shook the tank i could'nt see any coolant on the max mark on the outside of the tank.

Is it possible for the tank to be empty and it just leaves abit of coolant in the top of the tank, or if it was empty would i see nothing in there atall?

Thanks.

Here's how it should look with a cold engine. This is the 'normal' level. If you fill it too high, the excess will be discharged through the pressure cap when the temperature gets high.

When its dark shine a touch on top of the expansion tank then you should easily be able to check the level on the side marks as well.

Like most other 1.8 and 1.8T owners, I too am obsessed with coolant levels and check mine every 2 or 3 days. In my opinion, the tank is far too small and the narrow level between min and max causes far too much stress and worry. The tank ought to be a lot bigger allowing for more coolant to be available for these fragile engines.

Yes, we've done a lot of brain racking on that one!

Just out of interest I was talking to the mechanic that has a garage just down the road from me, who is an Aussie (I don't hold that against him tho') He tells me that back home it was quite common to re-manufacture the radiator with either bigger or more bores to tackle the extra heat there. Would this be a solution to the 1.8 coolant issue

The idea of increasing the coolant capcity in the 1.8 has been mulled around before of course. You will no doubt remember this thread: http://www.the75andztclub.co.uk/foru...light=capacity

Remanufacturing the radiator sounds like a major task and hardly a DIY project. It's amazing what these Ozzies get up to!

The focus on this issue at the moment is with the development of a digital thermometer to give a proper temperature gauge with warning buzzer. As long as the temperature is known, there should be minimal risk from overheating. More coolant would be a good thing of course. It would allow much more leeway should there be any leaks. However, this wouldn't prevent HGF in itself. Knowing what's going on temperature-wise is the better approach IMO.


Allus summat!
