Hi All- I'm a previous member that couldn't regain access to my old account. Usually I lurk and learn but now I'm needing some advice.
My 64 1/2 has been running hot for the last couple of drives. Even though the car has run "warm" for most of the 15 yrs I've owned her, this "hot flash" thing of late is getting out of control, last wk she stalled at a light while at the NSRA show. After 20 min it cooled some and, I was able to get it started again. Once on the open road, the air flow was plenty to bring it back to a normal temp and it ran great.
So this suggests that for some reason its now staying very hot under the hood...even though I've not changed anything major in the last 3-4 years.
The one thing I've had time to check is for coolant in the oil and it appears clear and there's been no rad issues & hoses all seem good.
I know this could be the beginning of a long slippery slope and need to check several other things before I make a plan but...have a cple of questions to ask of you to help me brainstorm the cause.
Q1. Would a possible blown muffler baffle be enough to cause it to run hot while idling or in stop/go traffic?
Q2. Could timing thats off make it run that hot?
Thanks for your input!
