Hello, I replaced the fuel cap and replaced the EVAP test hose inside the passenger side fender well since it was kinked and degraded. I know that hose just lead to a dead end but I was afraid it was leaking so I replaced it. And I haven't been able to drive on the highway in order to activate the EVAP monitor test within the ECU, so I don't know how helpful those things were yet. However, I have noticed a "gurgling" sound after shutting off the car and it is sound only heard with the hood open. And I know for a fact it is coming from the cooling system. Which indicated that there is air within my cooling system. Upon my recent replacement of radiator hoses switched to silicone I failed to even acknowledge the vent plug or bleeder valve sitting above my water pump. Apparently the proper procedure for putting coolant in my car is to remove the vent plug BEFORE filling the radiator. Then, you put coolant in the vent plug's hole until full. Then reinstall the plug and run the motor with the radiator cap off and fill radiator as necessary. And to NEVER operate engine with vent plug removed, which I never did that since I didn't know about the vent plug. So, today I removed the vent plug and put coolant in the vent plug's hole until I couldn't anymore. If fit about 6 or 7 ounces of coolant in this portion of the system. I did recognize that the tee that this vent plug is on has a pipe that goes right beside the coolant temperature sensor on the inside of the motor. So, I can see how they would affect each other. My question is, how will I be certain I have all of the air out, even if the vehicle starts acting right? Should I repeat filling the vent plug hole with the engine off, that is if I can fit anything in there? Also on my scan tool I noticed that my temp goes around 196 degrees after like 15 minutes of driving, which I am a little uncomfortable with that, is that due to the air in the system? I also know that the ECU only allows 7 minutes for the temp to be at 140 degrees or it will set a DTC for a bad engine coolant temp sensor. I know the engine coolant temperature sensor is fine because it is brand new. I see degrees on my scan tool because the ECU calculates it in degrees. With that said I do wish I had a reference in numbers in order to know rather I have resolved this problem. What would you call a normal coolant operating temperature on a 2000 mustang v6 3.8 liter? Thank you for your expertise!
