Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Replaced the thermostat in my 2000 Volvo S40 (the compact model they don't make any more).
Was getting a P0128 code and the Engine Check Light on. Googling says not coming up to temperature fast enough, but the temp gauge seemed to act normal, suggested to replace thermostat and temp sensor.
I could get the thermostat local cheaper than shipping ( $16 with seals), so I decided to try that first, and only replace the sensor if needed. But I don't have a lot of time now, I need to pass the IL air test (plug into ODBII port), and then order my plate sticker which expires end of June, and it takes some driving cycles before you can pass the test after a code reset.
After watching some youtube videos to make sure I wanted to tackle this, it looked pretty simple, so I got the parts this AM and went at it after lunch.
Well, the thermostat replacement was pretty straightforward. I sprayed the bolts with WD40 a couple times yesterday, and a couple today. Got out my manual impact driver to loosen the bolts with some twisting impact (I had a bad experience ~ 15 years ago, twisted the head of the bolt off changing a thermostat - ). All looked good.
But the guy in the video didn't drain any coolant, he said he just let it leak out. I see the alternator nearby, and decide that might not be a good idea. Unfortunately, to get to the drain valve, you need to remove the air deflector/shield thingie, with ~ 10 bolts and then there are 6 of those little plastic bullet connectors holding various parts of this together, that pop out and then I can't tell where they all go. On the bright side, the drain valve opened (and shut!) easily, no horror stories there.
And then taking the cover off on top to get to the thermostat (easy), but I see some wire sheathing that is all decayed from time/heat and crumbling. So I vacuum that out, and replace it with some I had on hand (that might not stand the heat, we will see!). Thermostat replacement goes well, button it up, return the coolant and start it, no leaks, all normal.
But then it must have taken over an hour to try to get those shields and plastic connectors in place. I almost gave up and started looking for my drill and a bunch of tie-wraps, but suddenly it all went into place.
Now, to see if the code stays clear - that will take a few days of driving and some cold starts. If not, time to replace the sensor.
