One for the brains trust. I keep losing coolant on my 206 1.4. To give an idea, I top it up then it will go from max to min over about a two week period - the car does very little k’s.
I use Nulon long life red, so any leak is usually pretty obvious as it dries a bright pink colour. Some facts:
The cap appears to hold pressure - it pops when I release it. I always screw it down fully. The plastic bottle appears OK.
There are no obvious leaks anywhere at the front - radiator, hoses, thermostat, heater hoses in the engine bay that I can see.
Timing belt was changed 4 years ago, but no idea if the water pump was done. It would have been done by Bill M in ACT who is pretty thorough by reputation.
There are no leaks visible in the cabin that I have seen - where do the orings and matrix normally leak at - where to look for leaks?
The oil cap is Ok - no condensate underneath; the oil on the dipstick is clear. Beyond that I haven’t done any leakdown test or similar. The car appears to maintain temp and while it runs higher than I consider normal, not what appears high for a 206 (generally 80-90 by the gauge).
The previous owner did have some heater O rings replaced twice over his ownership.
Any ideas on where to look/try next.
