On the return trip all was well while going forward but when we started to back up into our storage slot the overheating happened again.
Has anyone else had this experience or have any ideas what might be the problem.
Why did the mechanic change the T stat ?
What does reset THE sensor mean ?
Does the gauge go up, a overheat light come on or coolant overflow ?
Have you ever sat in traffic and seen the overheat ?
If you take it out of reverse, do thing go back to normal ?
Answers to all of the above will help troubleshoot the problem. If it happens instantly and goes away just as quick, it could be a weird, reverse light wiring thing.
An airflow issue would be just as bad stopped in drive as reverse. Its not like you are backing up fast. As far as water flow, its the same at idle in forward or reverse.
