Heat soak: Insulator wrap, Pros/cons?
I have used the search button and, came across mixed opinions.
I have major, major heat soak issues. I can idle it for 10 mins, and shut it off and restart it 5 minutes later with these codes. 1. P0300, 2. P0302, 3. P0303, P0304. They are 1. multiple cyl. misfire, 2. Cyl 2 misfire, 3. Cyl 3 misfire, and Cyl 4 misfire. So far I have taken the stupid insulator shield off and ran a switch to the aux. fan. It helped a great deal, but will covering the injectors and fuel rail in insulator tape help? Also will using a lower temp thermostat help? I need to replace it soon, because it is running a little warm. Letting it set will bring it up to 230F on a scantool. |
I would think weather is still cool enough that heat soak would not be an issue unless the motor is overheating. Thought the factory fix was insulation around #3 & #4 injectors. Sounds like your problem is more than heat soak.

The jeep runs great when it is cool, it idles smooth at 500 RPM and does not leak a drop of oil... |
Have u verified temp with a infrared gun pointed at the t-stat cover? Cooling system maintenance? How old r cooling components, fan clutch, radiator, water pump, etc.? Tune-up/spark plugs, etc.? 215F at 80F and below sounds like borderline overheating. 180F t-stat may help a little for another couple of months AND ONLY if the rest of the cooling system is in top notch condition.
T-stat only controls MINIMUM coolant temp. |
