Well holy smokes where does the time go? Last I checked into the forums was the end of September just before taking off on a week long road trip with my dad. We went from the greater Seattle area to check out the Hughes H-4 Hercules in McMinnville Oregon, down to Crater Lake, back up to the High Desert Museum and finally Voodoo Donuts.
The Sonic performed great, this was the first road trip I've taken with it and the elevation got up to about 9500 ft and you couldn't even tell. I love turbo cars.
Since getting back I've had a couple minor issues crop up. Upon first getting back my car triggered the CEL, I don't recall the code anymore but it had to do with the bypass valve, which was interesting because I've bypassed it. I figured it had to do with the elevation changing, I reset the code and it came back as a pending code for a little bit but then disappeared and hasn't returned.
The next thing that's started happening is my car is not holding the ECT steady anymore. It used to be rock solid at 199.4* on the Ultragauge but started fluctuating, sometimes getting as high as 217*. I believe the electronic thermostat control is failing, perhaps due to the increased duty cycle of specing a lower ECT via HPTuners. I'm not going to take it in for this, I'll just replace the part later this spring when it gets a little warmer outside.
The next thing was kindof a problem, it totally overheated while driving around for work on Queen Anne in Seattle. Was taking a client to the office supply store so he could get a couple things and when we were about a quarter mile from his office I noticed the Ultragauge was showing about 235*, uh oh! A short time after that heat stopped coming out of the heater, steam started coming out from under the hood and the Ultragauge was showing 245*. I was so close to his office that I coasted the last 100 feet or so into the parking garage, popped the hood and could tell that the steam was coming from behind the head on the drivers side.
Great. The water pump and thermostat stuff is on the passenger side so I was getting concerned that I had head gasket issues or something. At the end of the day I topped the reservoir with water using an empty Cristal bottle (lol) and drove back home keeping a close eye on the temp, I made it home fine.
Turns out the problem was the heater hose that comes out of the drivers side of the head and goes to the heater core fitting on the firewall had been rubbing a bracket and ended up rubbing a hole in the hose. $11.00 later and the new hose was installed, disaster averted.
