Why is my car making a bubbling sound and running hot while idling?

What is your question?

I had my motor mount: dog bone and front mount replaced 3 days ago and have noticed two separate problems in the last couple of days. First, I was sitting with my car idling before work in the morning and my car began to idle up and down (slightly- between .5 and 1 RPMs) then I began to hear a boiling, bubbling sound in the dash. The car also began running hot. I shut the car off after a few minutes and could hear it more clearly. The sound subsided after about a minute or less. Second, my car makes a low whining type sound when I am taking a slow turn to the right. It has happened when turning into my parking spot and also coming to a turn where I have to almost stop and then turn right. At my service appt, all of my fluids were checked and given the okay. Could this be from the mount being replaced wrong or maybe the fluids not being done correctly? They changed my engine oil and also my engine coolant.

What makes this problem better or worse?

bubling noise= shutting the car off ; whining from tire= speeding up or not turning wheel

How long has your 2011 Lexus ES350 had this problem?
