Codes and Problems
#11
Wonderful! Thank you Oldblue! I was also wondering about the fluid so thank you for the advice. Called GM and they have it in stock so I will spend the extra and get the better one. Sorry to have you repeat yourself but I do appreciate all your help. Got a code reader as well so hopefully in the future some of this is easier. Changed the gas cap to a GM one as well. Guess in some cases it really does make more sense to pay a little more than to do it a million times. Again thank you very much.

I just learned that gas cap lesson the other day (see my posts in What did you do with you HHR today) the $18.00 cap only lasted 5 weeks, but it was the only store open on a Sunday, Plus I had to get a ride pay for her gas , and time with a $20.00 trip to Starbuck's, man her Mother didn't like that! Apparently McDonald's coffee just as good and I shouldn't have spoilt the girl!!

Lol yes McDonald's Coffee isn't as good!! One more question should I change the ECT sensor at the same time? Or wait and see if the thermostat is the real problem? Problem with the code readers is that more than one thing comes up so I just want to do the right thing! As with anything this is a learning adventure! Wish I had the money to let others fix it for me!!

ECT should be fine, I did remove mine and clean the threads then used a sensor save Teflon sealant to ensure it had good contact but you might want to just change it out.
Have you changed the Evap sensor yet?

Good I thought maybe you had bigger problems so don't go looking for them but just an FYI
Some customers may comment about one or more of the following conditions:
• Intermittent no start
• Intermittent extended crank
• Intermittent start then stall
• Check engine light illuminated
• Intermittently functioning or inoperative electrical systems
Upon investigation, the technician may find DTC P0442 or P0449 set as current or in history. These DTCs may also be accompanied by other DTCs.

These conditions may be caused by poor electrical contact between the underhood fuse block (UBEC) and its connectors. This poor contact may be due a bent or twisted male terminal (as shown above) on the UBEC side. During assembly when the UBEC is bolted to the connectors, the male terminal contacts the edge of the mating female terminal and pushes the terminal (1) out of the cavity. When this occurs, the terminal lock on the connector breaks and the terminal will no longer lock into the connector.
Correction
Remove the UBEC from the connectors. Visually inspect the suspect connector to see if the terminal has been pushed out of its cavity. If the terminal has been pushed out of its cavity, the terminal lock is damaged and connector replacement is required. Also, inspect the terminal for damage and replace if necessary. Straighten the UBEC male terminal (use a business card as a straight edge). If the terminal is twisted, attempt to straighten it using needle nose pliers.
