Exclamation The Overheating Saga

the other day i was driving normally, just cruising around and i glanced at my guages only to see the water temp was beyond the hot notch on the meter. immediately i pulled over and popped the hood. to my surprise the engine itself was completely cool. however my car was leaking coolant and the coolant reservoir was hot and had some crud in it.
i am building car knowledge as much as i can but have never encountered this problem. right now i am thinking that i will probably have to replace the water pump since my car is about old enough to need one (115k miles on the stock pump still).

what do you guys think? i have a 99 RS

from speaking to other friends and family, it seems the most common response is that it was termostat failure. and that would be much better for me than water pump failure since the thermostats are pretty cheap i think (usually around 30$)

does this sound about right to other RS owners?

Seems likely. Do you see anything near the water pump, like wetness or seepage?

IIRC, this car has almost 120k on the car. Could very well be time for a water pump/timing belt plus thermostat. Drain and fill the radiator as well.

First though, I'd try the thermostat and see what happens.

the timing belt was already replaced around 100k and i know its about time for the water pump to be replaced as well but would like to prolong its life as much as i can right now. the dealer will be claling me back tonight with the results....i just am hoping that they dont try to con me into buying another water pump when this one still has some life left....but ill be careful. usually when i speak to the service guys after a couple minutes they realize that i know enough not to be conned and they stop making things up, but ive never worked with subaru before.

save yourself the headache and have it inspected...

i thought my 99 was just the thermostat... turned out to be blown cylinder #4..... have it looked at by a professional before you spend money and time on needless parts..

my advice anyway.

subie, already did that first thing i did was to have AAA flatbed it over to the dealer. i may have some mechanical know-how but not enough to trust myself with this problem.

These are classic signs of head gasket failure on the boxer engine. Pretty much requires pulling the engine, so you might as well replace the timing belt and water pump while they're accessible.

well, im not going to rush to that conclusion yet. i tlaked to the dealer a few minutes ago and they said they couldnt look at it yet because theyre short 2 mechanics so i have to wait until tomorrow to know whats up. why do you think that these are signs of head gasket failure so soon? it seems to me like thermostat failure is the most probable.

ok steve. i hate to say it but you were 100% correct. i cant believe that in a matter of less then 2 minutes my car went from very happy and smooth driving to blown head gasket and possibly even cracked block. the dealer said my minimum repairs costs, saying the block is fine, would be $1900 fixing the gasket and replacing the water and oil pumps. if the block is cracked? $3400. does this sound about right to you all??!!
im a college student with no money as it is....i am so very much not a happy camper right now...worried i might even have to lose my subie

I would check with other places before getting your head gaskets replaced.

A few weeks after I got my 2.5RS, the temp guage showed that it was beyond the hot level, so I took it into a shop the next day. They told me my head gasket was blown, and I said PFFTT, BS, so i took it to another shop. The other shop told me that my head gaskets were fine, its just that the coolant in my block heater was filled up wrong. I thought it would have been a thermostat or something but I was wrong....

So they refilled the coolant, and ever since, my temp guage has been fine

Default she will stay

OK...more news...

Well now, i have taken all the comments greatfully and am making some decisions here.
The RS is staying. I dont care, its mine, it stays. Thanks to NASIOC member FellFrosch i have the number of a well-spoken-of Subie mechanic in nearby(ish) Rochester who i will talk to tomorrow about my problem here, and will go from there. If indeed the block is cracked by some unholy bad luck, then i might even consider a wrx swap, but i wont jump to any conclusions here at all...i do like my NA 2.5 L very much.
Regardless, tomorrow i will buy a car cover and tell the dealer not to take my block apart just yet, waiting to hear what exactly is going to go on.
Wish me luck, I'll keep everyone posted on this saga.

PS. to offset my costs a bit i have decided to sell my 92 Legacy L wagon. I am completely serious about this. Should i put up the for sale tag here or in the private vendors forum?

another followup.
the subaru is chillin at Langer Enterprises near Rochester, awaiting its Wednesday appointment for a new head gasket, water pump, and oil pump. I'm considering asking to also have my intake silencer removed as long as its going to be under the knife anyway.
im wondering...would this be a good idea to do right after an engine repair like mine? i hear you should reset your ECU to take advantage of the changes. also would i have to deal with crappy gas mileage if i were to do this mod?

Default remove it

Go ahead and remove it. It's definetely not going to hurt anything, it's just a silencer. No, you won't get bad gas mileage. My gas mileage increased. After you remove it, reset the computer, let it idle for 10 minutes, shut it down, start up and drive away. Now air can enter the airbox freely, just remember to do something with the hole in the fender it leaves by removing the air collector. This will block out the hot air.

Alrighty, the subie is ready to be picked up! now i just need a ride out to rochester...
anyway, i have a n00b question here: how do i reset the computer? is it in the manual?

oh, and idle for 10 minutes? that seems a bit long to let carbon and waste gasses build up.

Default reset

Tons of information already on here about this. Anyway, unhook your negative terminal from the battery and hold the brake for 10 seconds, or you can just let it sit for 30 minutes with the negative terminal off. After that, hook the (-) terminal back up to the battery, press your transmitter to lock/unlock your car, and start up & let idle for 10 minutes. DO NOT RACE THE ENGINE. Let it idle, I do not know why. If you are worried about carbon build up, just thrash it after you've safely reset the computer. This will get your carbon out. Eventually the ECU will detect the difference in airflow, this will just give it a kick in the butt. If this isn't enough info for you, look around, there's plenty on this topic. Hope this helps.

Ok, my suvaru is back home!
now i must say, Langer Enterprises had to do more work than expected to fix my car, but the total price was about $300 less than what they quoted me, and about a grand under what SoA quoted me so kudos for them.

However, under hard acceleration my car feels like it is kangarooing a bit, and i can feel lit a lot in my shifter and i can here the engine struggling a bit. Is this possibly due to the car adjusting to the changes or am i getting misfires?!

Heres the list of repairs:
head gasket(s), water pump, thermostat, ignition wires

anyone have their head gasket replaced and experience this? by hard accel im tlaking the pedal is 1/2 the way down or more, i did slam it, just easing it there. if i was cruising at 3000 rpm, going 65, and put the pedal half down to get to 75, the car would accelerate but physically jerk forward and back a bit.

You could always do the ECU reset and check the plug wires. I had a bad plug wire one time that wasn't noticeable if you didn't mash the gas pedal. I would check the spark plug wires first, they are human and could have easily not got them on all the way.

the wires are brand new and installed correctly. i will be replacing the spark plugs and doing an oil change/ oil filter/ fuel filter tune up ASAP and hopefully that will work.
