Have a 2-week old Acura RDX, had 250 miles on the engine. Engine temp suddenly starts moving to the H-Hot (came very close to the top of the heat gauge) pulled over to let it cool, luckily I shut the engine before the 'engine is melting' warning sign came on, white smoke/steam coming out the hood (apparently from the coolant spraying on the engine). Long story short, I get it towed to the dealer.

Service found that the "hose for the heater core have come loose" The service manger said that the clamp was not properly attached from the factory. Said they ran tests to make sure engine had no leaks etc...

Well could have there been any damage? I'm just concerned that this screwed up my engine in the long-run. Thank you.

 

Depends how long you ran it while it was hot. I find that customers tend to lie in this scenario, as if doing so will some how prevent me from finding a problem.

MLS head gaskets are fairly robust and given the age and low mileage of the engine,Id say youll be fine if you stopped as soon as you claimed.

 

Gotcha, thanks for the reply. Yeah the tech said there was no overheat indication in the computer so I must have shut the engine off in time. I've read that signs of damage would be white smoke from exhaust with a warmed-up engine. It's been frigidly cold where I live so some white smoke seems to be coming out, but I'll keep an eye on it.
