Elusive coolant leak

[gregozedobe]

There are only a limited number of places where coolant can go:

1 External leak (most often from the thermostat/water pump housing on Golfs), look (carefully) for dried residue around engine bay

2 Internal into the engine oil (as blaast says, look for increase in oil levels and milky/mayonnaise appearance)

3 Internal into the exhaust (sometimes via combustion chamber), can show as excessive steam/moisture in exhaust gases (can use a "sniffer" to detect coolant in exhaust gases)

Note that these Golf engines are known for having trapped air in the system whenever the cooling system has been disturbed (and even from new). When the trapped air finally works its way through the coolant systems the coolant level will lower (mine did from new). As you were previously having coolant level issues before the coolant was replaced I think you are right to be cautious. Keep a close eye on the coolant level to see if it is consistently dropping, if it is then you need to find out why and fix it.

To get an accurate coolant level always check when the engine is totally cold. Checking when the engine is hot can be misleading.

Thanks Apologies for the very late reply. I don’t check this forum very often

Thanks

Did you get a resolution to this problem ? And if so, what was the issue and what was the fix ?
