Hi all, I am hoping someone can shed some light on this for me.
A while back I noticed that my coolant reservoir was below the Low fill level. Long story short, I monitored it, discovered that the radiator on these (13 200 Series) has a bad seam at the top where the P/N is that eventually fails and causes some coolant loss - this was noticeable at first by some visible, dry coolant near the top, then more obviously at the seem with more dried coolant.
I decided to pre-emptively replace the radiator because of some upcoming trips but kept seeing after the replacement that despite filling the reservoir halfway between Low and Full, after the car was cooled, the next time I checked the car again (after normal operation and cooling over night) the coolant in the reservoir eventually returns to below the Low level.
I had the dealer inspect, discovered the fabled exchanger leak (valley coolant) and got it all fixed.
What is crazy is that despite this, the car still shows the same issue. Filled between Low and Full when cool, driven normally for a few miles, check it next morning when cool and I've lost some coolant.
Car has 168k miles on it, impeccably maintained, dealer serviced always, using Toyota specific coolant, topped off when cool.
Pic shows where I find the coolant after any top off to the halfway point.
I would think these systems are sealed and I should not be losing any coolant - can someone explain what is going on? How should manage the coolant etc.?
