ENGINE OVERHEATING, dash lights flash, belts squeel, power steering lapses.

Not only is my engine overheating at idle and highway speeds, it seems I hear a squeaking belt and then brake, battery and rear diff lights pop on and I loose power steering momentarily, lights go off and the engine overheats.

Remedies?

Tribeca moderate overheating

Took my car to our local small town honest mechanic and he found that one of the coolant hoses had a tiny puncture that when heated spewed coolant and drained the reservoir thus overheating! Fixed and fine now!

Thanks for all your advice!:rolleyes:

Quick update on my overheating situation. It appears I solved the problem myself by replacing the radiator cap last Friday. Prior, any driving would result in overheating. After I replaced the cap, not one single overheat episode. Here's the thing: I had the radiator replaced by the dealer about 3 months ago. I assume the new radiator came with a new cap (at least it looked new when I replaced it last Friday). If it was new, I suppose it might have been defective?

Simple $10 FIX

$10 and FIXED! I own a 2006 Subaru Tribeca and it had been getting hot at idle or lower RPMs, I noticed it was fine for the most part on the highway or revving at higher RPMs unless it got extremely low on antifreeze over time. I haven't had this type of trouble After replacing my radiator and thermostat over a year ago due to a coolant leak but was dealing with it yet again. I replaced the thermostat yet again and performed a pressure test and found no leaks but still got very hot, one bar to overheating but never had I let it get to that point. The design of the water pump had me convinced it wasn't likely to be the problem. My fans were working and a test showed they cycled different speeds as designed. I was told head gasket and was ready to spend $2500 to properly do the job. It was explained to me that the head gasket let air in the system and an air pocket would form near the thermostat that would cause it to not open properly and revving the engine forced the air pocket out and would allow the vehicle to cool back down with the thermostat opening properly again, until another air pocket formed. THANK GOD! I didn't get the head gasket fixed. I noticed the coolant reservoir was low and as I was filling back up the system I removed the radiator cap and that's when I noticed a very small quarter inch section on the inner side of the seal had separated. The entire seal or gasket on the radiator cap looked fine except this tear that wasn't noticeable unless I pulled on the seal. Went to Autozone and I picked up a $10.00 replacement radiator cap, a month has passed and the system hasn't lost a drop nor has the temp passed normal, as a matter of fact most times it's a bar under midway. Problem was daily or ever other day at best and with no issues in a months time, no doubt problem is solved. My heart goes out to all those who spent thousands only to not rid themselves of the problem. I've heard some after spending thousands some trade the vehicle in because it remained an unsolved issue. Guys get a new radiator cap, bleed all the air out the system before you tackle any other possibilities with the coolant system. You may find just as I have that a defective radiator cap is letting the air into the coolant system that ends up forming a air pocket near the thermostat. Even if the seal looks fine, for $10 replace anyway. The spring could be bad allowing air in just the same.

it's hard to definitely say a headgasket is ruled out on EJ25D's and EZ30's. they can go months without symptoms.

i've had lots of Subarus with torn radiator cap gaskets (my EZ30 has one right now) and no overheating. i'm sure it's possible for some to exhibit symptoms and others to not, so that's not definitive either, but in my experience a torn gasket doesn't always (actually i've never seen it happen yet) result in overheating. im' not saying i don't replace them though, that would be silly.

sometimes a cap or tstat is combined with a proper removal of air pockets caused by the failing headgasket. and maybe the change mitigates things for a bit - but a recurrence of symptoms is all-to-common.

story after story like this too and there's lots of threads/posts like that as well. a "repair" fixes it. just look two posts up - at sweetpete's - good for two months. happens all the time, i could tell stories i've seen but who wants to read it all.

Hey all, over the last few days I've been experiencing what has been described here, moderate overheating while stopped that goes away once I resume moving. I was wondering how it all ended up for those of you who had this problem. Did replacing the throttle body gasket cure the issue? Or is this a symptom of a larger problem? A fellow on YouTube with a video about the throttle body gasket on a Tribeca said the issue was ultimately the catalytic converters going bad and causing exhaust to back up into the engine.

I'm interested to know what the mechanic charged to replace it vs the difficulty of doing it myself. Is there anything I need to know to do it myself, or is it just a matter of taking the car apart and reassmbling with a new gasket?

There are multiple threads on this forum that you can go through and see the end results, but generally speaking, the only definite fix I've seen anyone report for the overheating issue is replacing the HGs... and not to toot my own horn, but that was by yours truly (HG's were swapped at 148k, 2+ years later I'm getting ready to roll over 200k and my coolant temp hasn't gone above the center line even one tick yet.) But that doesn't mean replacing HGs is going to work for everyone... some people who did replace HGs ended up with some recurrence or related issues, so it's not a fix-all for everyone.

That said, the throttle body gasket is an easy swap, but requires moderate disassembly. Thermostat and radiator caps are cheap and easy jobs that might be a fix. But before going through all of that, a simple "funnel" test for bubbles in the coolant will indicate your eventual fix will require new HG's (at least).

I have not seen the YouTube video, but I wouldn't even consider changing catalytic converters unless you have a known problem or deterioration. Certainly not something I would do to fix an overheating issue absent any DTCs.

Thanks for the response. Just to be clear, by HG's you mean head gaskets (hoping you don't, lol)? And DTC you mean trouble codes?

What would new head gaskets cost to have done? What's the danger to the car in the meantime absent the overheating issue? What's going on right now seems manageable, but I know it's probably a matter of time before the damage gets worse. Am I basically without a ride until this is fixed? I just feel sick right now. Ive had this car less than two years and it's nowhere near paid off. I'm very concerned it's gonna take thousands I don't have to correct this issue.
