458 DTC - P0128 (Thermostat)

Hi everyone, the check engine light in my 2011 Italia is on. I had my car scanned and the DTC that is kicking off is P0128 indicating a thermostat issue. I'm not seeing very much in the forum related to this code. I'm wanting to check if anyone in the 458488/F8 forum may have experienced this one and the end result. Thanks.

 

So far, no. I only drove about 5 miles to home after the check engine light came on.

 

Thanks flas32, that's good feedback. I will check it out once the weather clears up. I'm thinking to just change the thermostat. Looks like it comes from Ferrari with the housing and not just the thermostat. Your thoughts? Thanks.

 

Got it; Ok, I will do some testing and checking, as suggested.

 

Hi everyone, I'm just getting to look into the P0128 (Thermostat) DTC with my car. I checked the coolant reservoir bottle and noticed that it was empty. I filled it with water (I'm planning a coolant flush as soon as the DTC problem is figured out) and let the car run about 10 minutes.

The temperature reached about 170 degrees (F). I noticed water leaking out of the side of the coolant reservoir bottle. It has a hole in it.

I'm thinking this may have been caused by the thermostat not opening up and maybe causing pressure to build up and caused the reservoir bottle to burst.

Does that sound reasonable? I appreciate any thoughts. Thanks.

 

Yea, good point - Thanks. The water was not moving in the reservoir bottle that should be an indication that the thermostat is closed, as well..

 

Hi triathgeek,it was only your bottle and nothing else that caused it?

Thanks. It'll work out.

 

It helps. Thanks very much triathgeek. I think I am going to go ahead and just replace the thermostat along with the tank and cap.

 

Hi everyone, I have the old coolant tank out of my 2011 Italia. I am ready to change the thermostat and hose that runs from the coolant tank to the water pump on my 2011.

I am looking through the 458 service manual and it is giving instruction to remove interior panels (section E4.04) and the engine inspection hatch (section E4.06). I really don't want to get into removing interior panels if I don't have to.

Anyone, know if the thermostat and coolant tank/water pump hose can be changed from underneath the car by removing the main under body tray instead of messing around with the interior panels and engine inspection hatch? Thanks.

 

Anyone on this? Looks like I'm going to be the guinea pig here. LOL!

Hi everyone, for the record, I am done with coolant tank and cap, thermostat and temperature sensor on my 458. I want to confirm that I was not able to do so without

Hi everyone, I am done with coolant tank and cap, thermostat and temperature sensor on my 458.

For future reference, I saw a video by Normal Guy Supercar that he was able to change the thermostat from underneath the car on a F430. I was not able to do so from underneath my 458. My hands were to big. I had to remove the engine inspection hatch like the fsm instructed.

While I was at it, I went ahead and changed hoses (part #s 262476, 86091700, 266873 and 268188) since they were accessible with the engine inspection hatch removed.

 

Yes, thanks for your help
