Bubbles in header tank

Postby Norbertflyer » Sun Feb 16, 2020 11:22 pm

Getting significant bubbles in the header tank after 7 minutes of running my 124k 3L V6 x350. Cap off of course. Presume this is just boiling from the engine cylinders? I'm also losing about 200ml coolant for every 50 miles. I also have cold drivers side cabin heating. I did fix the drivers side heating for a little while after flushing the heater matrix (twice), but it only lasted a couple of weeks. Also getting a bit of condensation on the inside of the cabin windows, leaving the car for 30 minutes after a drive. Temp guage reads normal. That's all the symptoms I can think of. A possible single, or multiple issues?

Radweld in the end........ All issues appear to be solved, except for the condensation, but it's not the right time of year for this to be present. Never liked this solution, but I'm not complaining (at the moment).

You say condensation? Is this within the car cabin?

Years ago we had one of the first Rover 820 vehicles. It didn`t take long before issues started. The car used to steam up badly internally and there was a shocking smell of curry present. That was a clear case of the heater matrix being pin holed and causing water vapour to escape into the car. Finally the car became unusable as we couldn`t see out of the car without opening all the windows. Being miles from any garage or motor store, the best we could do was buy half a dozen eggs from a small village store. From those eggs we extracted just two egg whites and dumped them in the header tank and re-filled the coolant system with a litre of lemonade....all we could get on the day. We returned home, drained the system and refilled with the correct anti-freeze coolant mix. That car went on without any further leaks or curry pongs for another seven years before we finally traded it in for a couple of hundred quid.

Heater matrix units are now available again from Jaguar as I recall for about £160 plus vodka and tonic. Glove box out, a load of in footwell dismantling and about three hours labour for someone who has done the job before. Lack of heat on the drivers side is usually the indicator that the twin core ie passenger and driver matrix is blocked. Pin holing is obviously another matter probably down to old age and matrix corrosion.
