my wife's car has electric water pump and electronic controlled thermostat

when I was parking the car in a mall 10km away from home recently, the radiator fan suddenly kicked into high speed, a few seconds later, these dreaded red messages popped on both screens, no check engine light, my OBD scanner was at home so I didn't scan the car on the spot

I popped the bonnet, expansion tank level was good, no visible coolant leakage trace around engine bay and sump guard, no evaporated coolant scent, engine bay heat seems normal...

I let the car cool down for 3 hours, it started and run normally, in less than 400m, from B2 of the car park to the street level, the coolant temperature shot through the roof and the engine power was limited, so I stopped the car immediately at the road side and called a tow truck to tow it to the workshop

while waiting for the tow truck, I felt both the radiator and expansion tank with my hand, radiator was luke warm but the expansion tank was too hot to touch

I left a note on the dashboard for the workshop on the symptoms and my suspect of electric water pump and/or thermostat failure

they scanned the car and found an error code on seized water pump, strangely it didn't pop the fuse, they replaced both the EWP and thermostat, finger crossed

car is 2 years 2 months old, 82,000km 

it caught me off guard, before it failed, there was zero warning

- zero leakage
- pump was silent
- no fuse was popped
- no error code
- zero warning message

it worked until the last second and kaboom and I have only a couples of minute to react, imagine cruising on busy highway

the combo looks like a giant frankenstein artificial heart, the plastic part is the thermostat and the cast alloy part is the pump

now I missed the good old KISS (keep it simple stupid) mechanical driven pump and thermostat 🙄

 

 

What was the cost of the part? Assume you used back original OEM

Nowadays with electric water pumps, its quite normal to fail "silently" and suddenly, mine also start failing recently (check engine light) but I can still drive the car whole day without engine overheat light (Prius), just dont piah the car on ICE for too long (i.e. > 60km/h).
