Different issues

[JaysLS]

I'm having a few little issues I would like to clean up with my 2004 LS8. I would really appreciate your help with these since I'm no mechanic.

1. My back up sensors are not working correctly. How do I change them and do I need to purchase anything other than new sensors?

2. Also, when I start my car in the mornings, and turn the temp to 90, it doesn't blow warm air. It's a little warm, but not hot. After a long period it will start to blow warmer air, however, it's never hot. Is this a heater core issue or something else? The A/C works fine so I wasn't thinking it was the DCCV.

3. My fuel mileage isn't correct. It's 4 miles to work from home, but my mileage always subtracts 8 or 9 miles during the trip. Is there a sensor I need to replace?

Thanks so much for your help and input.

For the heat, check your thermostat. It is probably stuck in the open position and not allowing the engine to stay warm. I started out with this problem a few months ago and then it threw a code for the thermostat. I changed it out with OEM parts. It is ironic you are having this problem because I am having it again. It is good that I have the one year OEM warranty and that the thermostat on these thing are not hard to change. Maybe thirty minutes if you know what your doing.

In August, I replaced the thermostat/gasket, overflow bottle/cap, engine coolant temp sensor, the thermostat housing and another part attached to the housing. I had a guy at the Lincoln dealer do the job and so far I've not had any cooling issues. So I hope that it's not my thermostat already.


I love the Lincoln LS, in fact it's my favorite vehicle. However, I might have to get rid of it for something more dependable. I've never had any problems with F150s, so I just might have to go back to that.

Everything with the LS seems to be the picky jaguar engine.
