Gen-2 gauge indication vs. actual temperature

GAGE Reading..........ECTS Temperature..........Event
.....1/4.................................150 F
.....3/8.................................192 F...................T-stat cracks open
.....3/8+................................195 F
.....1/2.................................212 F
.....9/16................................221 F...................Fan ON
.....7/16................................210 F...................Fan OFF coast to 205 F

NOTE. gauge mechanical accuracy is +/- needle width.

The Gen-3 is a digital signal that is used to drive the cluster indicator. The Gen-1 is a nonlinear gauge.

REWARD EXCELLENCE!

Default Re: and so it begins....

More updates to the 99 SL2. I installed seat heaters in it a couple weekends ago.

I had done a write up for my other car some time ago and I took the time to enhance that thread with photo instructions on how to set up the switched power from the UHJB. The thread is called Seat heater install with pictures.... and the post showing how to set up the fused and switched power wire from the UHJB is within Post 8.

Here are some photos of the switch location from that post to document this upgrade

Replaced the left front hub/wheel bearing assembly. Timken hub/bearing assembly was replaced under warranty with 11 mo & 16,280 km usage. The right one is still the same that was in the car when I bought it and I've put almost 40K on it.

The SL2 is chugging along just fine....

1999 SL2
2001 SL1
Default Re: and so it begins....

So just over two years later I had a re-occurrence of the weird no start condition from the quotes below earlier in this thread (post#138-147). Exact same circumstance, snowy mild day, started car, moved it, turned it off and it sat for a few days while we were out of town. When I went to start it, it started for a few seconds and stalled out. Had a hard time getting it going again but it finally started but was rough for a minute and smoothed out. It think we decided it was a stuck valve or two last time.

Otherwise, the SL2 is running great under brutal winter weather conditions this year. Extreme polar vortex cold starts and lots of snow.

It had sat for 4 days in mild winter conditions with about 6 inches of snowfall. Before cleaning off the snow I decided to start it to let it run for a few minutes.

I engaged the starter and it started up like normal with no hesitation, ran for about 3 seconds then quit. I engaged the starter again and while I could hear the starter running and light puff puff puff from the exhaust the engine did not turn over - it sounded quiet or weak. I believe I ended up flooding the engine before I thought to push the accelerator to the floor. I left it alone and took the other car to work. I could smell fuel.

When I returned from work I tried again and had the same experience but the engine sounded stronger this time with a couple catches. After a couple minutes of cranking and letting it rest I was able to get it to fire and catch and I brought the rpms up to about 4000 and held it for a minute. It sounded and felt like I had a slight hesitation or miss at those rpms.

I let it idle for a while to bring the engine up to operating temperature and drove it over to my mechanic to see if he could find anything wrong the next day. It drove and ran fine, I turned it off and restarted it and left it there.

My mechanic wasn't able to reproduce the problem. It started easily from cold and the engine ran perfectly. He changed the oil for me and I took it home. It started fine this morning no problems.

My best guess is that it lost spark for some reason as it clearly had fuel based on smell. I suppose that the weak/quiet engine sounds was due to no ignition of the fuel. The puff sounds from the exhaust was the starter cycling the pistons perhaps.

What are everyone's thoughts? I have no history on the coils, wires or spark plugs. Any other component that may come into play?

Read down in this thread a ways: http://www.saturnfans.com/forums/sho...d.php?t=202474 The sticking valve info is after the post where the OP returns with good compression numbers.

I did not let it warm up at all; it was run for less than a minute from cold start. Oil would have been close to ambient temperature when shut down which was about -8 Celsius (18 Fahrenheit).

I'd still like to read the TSB if anyone has a copy.
