Advice please - kids overheated 2.0L to the point of possible no return!

[rambler]

First off thank you for taking a moment to read about our problem

2009 Mazda 3 2.0L standard emissions. Hose above radiator fan popped out of the 2 holders, flopped over and got chewed up by contact with the fan.

Daughter driving car while this happened, lost all coolant and car massivley overheated.

I tried to restart car but sounds like timing chain/belt is gone as it just "whirrs"

Engine was freakin HOT. She said white smoke out of exhaust before she was able to pull off interstate and stop car.

Question is...55,000 miles on the engine, Is my best here to consider replacing the entire engine, or get it checked out for a possible rebuild. Im assuming the heads got
warped and needs valve overhaul. Not sure if it would be worth the money to have it all checked out or just replace the engine. Cost wise and down the road reliablity is a
concern.

Thanks in advance for your time. I live in the Fort Worth Area if anyone can recommend an honest mechanic. Not sure if this forum allows that or not, so I apoligize in advance if
im stepping out of bounds.


THANKS

Mike

Probably warped the head. If you can do that yourself I'd say go for it. If not, probably cheaper and easier to just get a replacement engine and swap it in.

yeah with the over heat like that Id say the head is probably gone....warped and possibly cracked...Id get a new head for it. Id start by tearing the head off of the engine to make sure the rest of the engine is ok....mainly the pistons.....it is unlikely but if overheated enough it can cause pre-ignition which can burn holes in the pistons.....again it is rare. probably just needs a new head and youd be fine.

the noise your hearing when your trying to start it is lack of compression from the warped head and blown head gasket.
