  • Опубликовано: 14 янв 2024
  • My 2007 Subaru WRX STI went through an entire fresh build as we bought the car blown up. it ran great for 18 Miles then I wanted to return to the grave that I dug it out of. The STI Continues to overheat and the Thermostat will not open, at first, we tried vacuum bleeding it, Burping it, Swapping the thermostat, and more. Ultimately I decided to pull to the engine, and redeck the head, to get this thing sorted. We finally tracked down the issue and I am so glad to have this thing working again!

    Tanner! Bummer that you had an issue with the pump :(
    Like Tanner mentioned, this is a first for us as well, so of course we have to go down the rabbit hole of figuring out what happened. We are in the process of getting the pump back, and will do a full diagnosis on what the issue may have been. Well also be going back to our vendor (who has made millions of these pumps, including the one in my STI) to work with them so it doesnt happen again. -Mark

      No process is perfect. It's all what you do after issue is found and you guys are doing all the right things. Especially getting it back and figuring out what is going on. Since there were bubbles, maybe some cavitation? Then again the heads were not super flat and some coolant was getting into the combustion chamber... it's a fun one. Good luck with the diagnosis!

      Especially the parts being produced (rebuilt) now. Better to go OEM as they seem to have a lower failure rate. On my vehicles, I have a 30% failure rate on AutoZone and Rockauto parts in the last two years.

    Any part OEM or aftermarket can have issues, there is QC measure but on big quantities full inspection can happen every 50-100 parts or more if no issues are found in full inspected parts. It’s all about diagnosing symptoms & sometimes there are more than 1 issue at play. Patients and open mind like you were got the job done.

    May be same reason us RB engine people have overheating issues with daily. Using the "upgraded" N1 water pump designed to flow more at higher rpms so engine can seem to overheat at idle when hot but not when driving. So most people go back to stock pump and it's more street able. Compare design of impeller from stock to upgraded one you have

    My quad four cavalier is doing the exact same thing at 155k. It’s never had the timing chain or water pump changed. I tested for exhaust gasses and the head gasket appears to be fine. It happens randomly but only appears to do it when it’s cold outside. Same deal no flow cold radiator at idle but when it’s hot outside it has no issues.

    @trentborg2230 6 месяцев назад

    So this has me thinking about what might be the real problem with my v6 sti. My rad has fins that are leaking, but in the video, you mentioned the cooling system being open. When i burp my car, the temp gauge on the dash reads right about what normal should be. But after i burp it and let it run for about 5 minutes, the gauge will rise. I'll wait till the next morning, and I'll add extra coolant to the surge tank, and that will help my temps stay lower a bit longer, but they eventually still get pretty high. I do have an aftermarket gauge i need to install, as well as stock rad i got from a buddy since the rad i bought for replacement went on back order after purchasing. What confuses me is that the leak is so small. Even after a week, there's still very minimal coolant loss. Like, im just about a third of the way through a jug of coolant in over 2 months. When opening the cooling system to burp it, the temps are normal, but when throwing that cap back on, the temps rise within 5 minutes. I can understand there is air getting in the system. That's why i burp it so frequently, but at idle, immediately after burping and closing the system, temps rise. Im hoping it's just the rad, but something has me feeling it's possibly something else.

  • @06hawkeye88
    @06hawkeye88 6 месяцев назад

    I have the same car. It’s happened to me multiple times. The problem is that the coolant temp sensor is on the top and it gets a small pocket of space that has air trapped until the first time the thermostat opens. The car then shows a much higher temp than the coolant is on the very bottom and does not open yet because the temp to open isn’t being seen from the thermostat. Still do not let it over heat on the gauge ever so shut it off let cool for 5 min and start again because it takes time for the temp to be passed from the metal of the engine to the fluid in the coolant channel. By the third start it should work. This happens on this car every time I pull the motor which has been 20+ times and since I figured this out I can get it to work correctly every
    single time.

    I think the Water Pump impeller wasn't pressed onto the shaft to the correct position, which would cause the operation of the impeller to be inefficient i.e. if the clearances of the impeller isn't right in the Pump cavity/housing, it's ability to function correctly. I bet when Company 23 get the pump, they will find that the impeller has either been pressed to far onto, or not enough onto the shaft. At least you fixed it tho! Great!

    Hey man, been watching you for a long time. This is an interesting issue. I was having a similar issue with my 12 wrx, but my issue was resolved when I changed thermostat and upgraded to a mishi rad and did cylinder 4 mod. But I had a question...why is it even getting up to 200s in temp with ambient Temps being so low? It's been between 30s and high 40s here in oregon and mine won't go higher than 180-185. I usually only see the 200s when it's summer. Any thoughts on that? Just chop it up to different years and tolerances, mods etc or? 🤔
    Main difference between our builds(that i can see) is im still stock block and turbo and yours is built and GS turbo. But besides that i have every other bolton etc you can do.

    I don't have bubbling coolant in the overflow, no chocolate milkshake, it hits high when I'm driving, not at standstill, my timing belt, thermostat and water pump were replaced by the dealer maybe 2 years ago, zero issues that time.
    It'll go down, it's cold here too, it went from like 231 to 172 lol. I'm at the point where I think I somehow introduced air into the system and I'm finally at a point where I got a couple hours to let it cool, then bleed it. I got one of those funnels too, so at least I just gotta mostly stand there lol. Hopefully this is it... or a thermostat.. not my damn HG, but MLS HGs and it's mostly stock..
