I posted a thread in Problems & Fixes, but recieved little feedback. Thought I'd try again here, as I am nervous about it.

A hose was not re-connected properly when i replaced my air filter. On my drive home the car overheated. I drove with the needle at H going 60ish for 3 or 4 mins before i pulled over, hoping it would correct itself. When i pulled over i noticed the hose was disconnected, the one behind intake manifold, and coolant was now low. I poured in a jug of generic coolant a friend brought to me, and drove the rest of the way home without issue. I have not driven the car since.

Could this brief overheating have caused any permanent damage? Could the different coolants in the engine react adversely? I am taking the car to get the coolant flushed and oil changed Saturday morning just to be safe. Should i be doign anything else? Any help is greatly appreciated.

 

It's really hard to say if anything was damaged without running it since it has happened. I would make sure there is the right amount of coolant in, crank it up and see what happens.
If it starts acting up, shut it down right away and bring it in asap!

 

I had to move the car this morning for alternate side parking and everythign seemed/sounded normal, granted the car was only running for 5 mins.

 

In your other thread, you said 2-3 minutes. Here you say 3-4 minutes...It's hard to know about possible damage. Are you sure you know exactly when the needle started to rise? Maybe it had been at "H" much longer that you thought? Maybe not.

If it was only 4 minutes, you might be OK. It's really hard to say with aluminum block engines. It's also possible some warping took place and you'll be in for a blown head gasket farther down the road. The only way to know for sure is to pull the head and have the block/head checked for warping. Rather than do this, you're probably better off just waiting to see if the gasket blows. Then you have to pull the head for sure.

If the coolant you used was non-silicate and designed for aluminum engines, you're probably fine, although personally I'd have the entire system flushed and replaced with Honda coolant. Be sure they pop the engine block plug to get all of the coolant and not just the coolant in the radiator. There was a recent thread on this. Do a search. If you have a dealer/shop do the flush, insist they pop the engine plug.

Here's what the owner's manual says:

If Honda antifreeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporary replacement. Make sure it
is a high-quality coolant
recommended for aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malfunction or fail. Have the cooling
system flushed and refilled with
Honda antifreeze/coolant as soon as
possible.

 

Thanks nfnsquared. Haha yea, your right, i revised my estimate slightly. Couldnt have been any longer cause i noticed it right when i left to head home. And the RPMS were very low for those minutes where the temp was high. Hopefully no warping. My saturday apponitment is at a dealer and i will request the plug to be drained as well.

 

You should talk to the service department before Saturday to be sure the techs know how to get to the plug....

 

OP- I am moving this 'new' thread of your to the problems subforum where it belongs but I wont close it since it is a repost. Hope you understand but we like to keep things organized here.

 

redlined high temp = blown head gasket
not today,, but within 6 months is the average
Get an aluminum head hot once= its a gasket replacement- no big deal
get it hot a few times and its new head time~
