Overheating 360 new engine

As I said earlier in this thread, sometimes the cause of the problem [ o'heating in this case ] cannot be found, despite best efforts.


I know of a Suzuki Swift that had an engine check light that kept lighting up. Everything in that car that could possibly cause the problem was changed but the problem persisted: new engine, all the sensors, wiring harness, etc. Suzuki gave the customer a new car & the old one was shipped back to Japan.
