The coolant hose blew off the radiator and caused a mess on my windshield while driving on the freeway. Unfortunately I couldn’t pull off the road right away, and hopefully it didn’t cause too much damage to the block? The car went from 200 deg to about ~400deg in the matter of seconds, hot enough to melt the rear bumper and parts of the trunk. Sucks for me! The dealer is running a compression test to see if any damage occurred. I am a little worried about the stress that the block has undergone. I know that aluminum and steel heat at different temps but I don’t know what the outcome might be as far as warping and gasket problems. Any (good) advice would be helpful.

 

you should be ok, i blew my freeze plug 2x and overheated, just the hg got damaged, the head was sent to a machine shop to get cleaned and checked

 

is your an 05' model? They did have a recall on the hose I believe.

 

Fortunately the dealership is taking care of the problem. They’re installing all new headers and exhaust. I think they should replace the whole car with a 9 mr.

 

The bumper melted in the rear from the engine overheating? How does that work?

Why are they installing "new headers"? I'm assuming you mean the single exhaust manifold, but I don't know what would have happened to it...

 

yeah what do the have to replace the turbo manifold for? that thing is a hoss, i can't see too much going wrong with it...

 

Most of those guys at are clueless!

 

The exhaust got hot enough to melt the bumper. I told the guys to do all the necessary test to make sure everything is ok. They said that they needed to replace the headers and the exhaust system. I wasn’t going to argue with that. I more worried about the internals.

 

First thing-do a compression test. Also check your engine oil and your coolant to see if they mixed. If you find oil in your coolant (or vice versa) that means your head gasket is done (and your head might be severely warped). If the compression checks out, and your not blowing out white steam out the exhaust, you should be OK. Good luck!

 

There was quite a bit of steam and coolant coming out the exhaust.

 

Your headgasket is done. You will need to take the cylinder head off and have it resurfaced. The hot steam is probably what melted the bumper. I'm sorry to hear about your misfortune, Good luck with everything. The block should be fine, it would take some serious overheating to warp any part of the block (cast iron).

 

Thanks for the imput. It sux due to the fact i dont drive the car hard at all.

 

I am assuming that I should change the plugs and oil, but what else should I do?

 

Dont worry my freeze plug blew 2x and it overheated badly. I got a new hg and i had the head checked to make sure it was to specs. the 2nd time it happened i was driving at normal speeds and it just started overheating.Make sure they also check the pistons

 

Head is likely warped, maybe even valves. Coolant in the cylinders in any considerable amount is bad news. The head should be checked out.

Secondly you should have not continued to drive the car, no matter what.
