Well it came back on again. The first time was about 200 miles ago - it was an evap leak and was seemingly fixed. I remember my mechanic mentioned something about not being able to "access the solenoids" with his computer and if it came back on he would take it to the dealership for me.

Anyways yesterday I was on the highway comming home from work when I hit the gas to gain some quick speed and brought the rpms briefly between 5 and 6,000. Thats when the light came back on.

Will go to Autozone to pull the code as soon as I can, but any early thoughts for now???

Code P0128 Coolent Temp Below Thermostat Regulating Temp


I checked coolent level - it didn't seem "low" but I topped off anyways - light still on for now

Btw - I havn't noticed any performance issues, and the outside temp is in the mid-upper teens these days

 

how much does autozone charge to pull codes?(just wondering)

 

Sam-- They do it for free.

So, I found the thread on this issue - Tech says to replace both thermostat ($16) and Sensor ($66)

Question - can I still drive the car? should I drive it today to see if it just needed that extra coolant? Can I do-this-fix myself?

 

I would say that you can still dirve the car, if its not overheating and not acting up, but i wouldnt go on any road trips. Oftopic question, what type of coolant do i use in the resevior to teh left, it says use only volvo coolant with 50/50 mix ratio. and to not mix it with other coolants, is this some special coolant I have to get from volvo?

 

No you can use any coolant.

You can drive the car as long as it drives fine.

 

Thanks tech - seems to be running normal after 30 miles of driving today
