So we're all aware of the valley plate leaks, radiators, andwaterpumps that could go out on this car. But has anyone addressed how much coolant is lost just by evaporation (if it does)?

I got my water pump replaced around 2 years ago and my valley plate done 3 months ago. So I wanted to figure out if coolant loss through natural operation was normal...how much and for how long. Would a loss from hi line to lo line in a span of a year be "acceptable"? or would it be longer than a year?

 

Not sure what an acceptable amount would be..but i can tell you that since my valley plate fix, over two years ago, my coolant has been at the full mark. All of my other Toyotas have always stayed at or near full as well. I had to top off my dad's 97 Camry once but he had over 220K kms.

 

Had the car over 3 years, in 3 years I've done 19000 miles. 124150 miles on a 2008 year UK car. Never had valley plate, water pump or radiator leak. Coolant has dropped about 10mm from max in this time due to evaporation.
Just to mention oil level doesnt drop a bit between oil changes, I change oil on average about 7000 miles.
These engines are really well built.
