Octavia mk1 tdi coolant leak

Many thanks! We're for sure enjoying the time with our little one.

I've changed o-ring number 5 and 9 on the car, they were both leaking, especially number 9. I've done a quick test run, still too much air in the system (though for testing purposes I've had nearly only water and very little G12 in there, maybe a bad idea, but its summer now).  On idle the cabin heater do most of the time work. Driving the car the cabin heater does not work and it was overheating still.

So even though I've changed the thermostat earlier I decided to remove it to see if it was broken or not, and if I with no thermostat would get it to a ok temperature / not overheat. Havn't testet much yet, but no overheat, no cabin heating while driving. Need to drive more to be able to test and hopefully get more air out of the system.

I've also successfully adjusted the diesel pump timing. Timing belt seems to be fine, just probably not needed to do the job given that the waterpump was okey in the first place.
