Honda is saying my 2008 CR-V engine has experienced hydrolock. The car is “Certified” and I’ve had it for six weeks. Here’s the sequence of events:
-Hot, dry So Cal day – great road conditions
-No MIL indicator, temp gauge shoots to “hot” > dash lights, lost compression > pull over
-Engine off/smoking (none from exhaust)
-Coolant tank empty > refill > wait 30min. > 0 leaking
-3 restarts w/difficulty (starts each time)
-Drive car > compression is normal
-Stop car > check coolant (full) > restart the car > start-up/compression fine
-Drive car > temp gauge/compression fine, MIL on
-Stop car > check coolant (full) > restart (no issue) > drive > compression/temp gauge fine, MIL off
-See #s 2 & 3 > check coolant (full) > car won’t turnover/battery dies
-Car towed to the Honda dealership > Honda investigates
Road debris (they suggest a rock) entered my fan and hit a blade, which shot it through the bottom of my radiator. They said they couldn’t spot the puncture until they removed the fan, and said when they did, it was “pouring” coolant. Pouring. During the first overheat, the head gasket blew and created separation between the gasket and the block. Coolant leaked into the separation and into the engine block (mind you the puncture is at the bottom of the radiator), into the cylinders and caused the engine to hydrolock. The engine is finished; the car needs a new one. $7300+tax for a used engine with 57k miles (mine had 70k). “Impact damage” – Honda won’t cover.
I am not a car guy and even to me this sounds ridiculous. Apparently my certified Honda engine can be destroyed by a pebble on a warm, sunny, Southern California day. Is this possible? What’s my next step?
