Which is why it cost £100+ for the swap in materials alone 3 years ago. Yes, that study was put together by a direct competitor. And they would say that, wouldn’t they.
Evans issued a technical rebuttal:
My other car is a 2004 Jaguar XJ8, with about 115k miles on it. When brought, the coolant was fresh looking correct pink HOAT. I had a bit of a coolant loss issue. On these cars, the number one culprit is the expansion tank, and a crack around a tube connector. But no, mine was perfect. ecently had some work done on the car, and asked the Jaguar Indie to pressure test the system.
Initially he couldn’t find the leak, until he was taking the car off the lift, and the bottom of the radiator decided to lunch itself. I guess the weak spot exposed itself in a classic example of coolant corrosion.
Of course, I’m not planning to keep the Jag for the long term (though next time I might get a XK 5.0), so regular Jag coolant in that.But the Mazda, with the use its getting, I’m likely to be doing a next water pump and cambelt sometime around 2027, provided the car hasn’t dissolved by then (but if it does, the engine will have perfect galleries).
