Once the bracket is clear, pull the housing, swap the thermostat, and put it right back together. You won't lose but about a cup of coolant. You will need to have the SES light reset. Autozone will scan the code for you, and then hand you the reader to reset the code. I think for liability reasons they cannot reset the code for you.

I have a 2005 jimmy , i had a p0128 and changed the thermostate, was reset and showed the codes p0053 and p1133. the engine light came on a few days later.. why after fixing one code two more appear.. (two oxgen sensers were also replaced previously).. I only have 36.000 klms. I know short driving distances are harder on your car, but this is awfully frustrating...as a previous owner of a 1997 astro van, i didnt need any serious work on it untill it was over two hundred klms.. could you tell me pls tell me what i need to replace. and also do you have a 800 number where i can phone and get a service manual for my jimmy,,I had one for my van and it was one of my better investments as my hubby does most of the work thanx

Replying to: die (May 12, 2009 3:28 am) Is the engine warming properly now? As in going to 195F (90C) within a short period (<5 mins) |

The code reads "Secondary air injection - incorrect flow detected...please reply if you have had experience repairing what may be causing this code to cause the service engine light to appear. Had a complete tune up last month and soon after the service engine light popped up. I took in back in to the dealer and they changed my thermostat. Now I'm getting a PO410 code. I didn't take it in for service yet - thought I would try this forum first. Hope someone somewhere knows - I really like my blazer but I have already replaced the trans. which set me back big time. Now it's just general maintenance but the engine light code my be another big expense. Thank in advance for your input. VGK |

| I would first check or replace the EGR valve on the engine. They can get stuck with carbon deposit in a high milage engine when the vehicle is held at a continuous highway speed above 60 MPH for about three or four miles. That especially occurs after the vehicle has been in slow stop and go traffic for a few months. When the SES light comes on, stop the car, turn off the igintion for ten seconds and the SES light will go out. That is what I have to do on my 1991 S10 Blazer. I fixed the problem by driving at 80 MPH for about ten miles about once a month. Tell the police that you are testing your EGR valve, .I am sure they will understand. | |
