Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** is a fairly common problem caused by failed ignition coil. Use a spark tester to see if each coil can jump a 25kv gap and replace any coil that seems to have weak spark. Let me know how it goes or if you have more questions, thanks.
If temp goes back to normal range after shutting off for only a couple minutes that would point toward there not being an actual overheating problem. Does heat ever work? Does vehicle ever run like it should for any long periods? Thanks.
A bad heater core can cause overheating but not usually. At this point I'd suspect a clogged heater core or head gaskets. The coils are common to fail causing gauge to spike and put vehicle in safe mode but from your description it sounds like vehicle is actually overheating. So at this point I'd flush out heater core with a garden hose to see if that helps if not do a combustion test which checks for exhaust gas in coolant, if exhaust gas is in coolant this means head gasket is leaking. Let me know how it goes or if you have more questions, thanks.
You will need to buy combustion tester, I know you can buy them on ebay for around $65 and it is something you can do at home. You should be able to buy same kit from your local parts store too. Let me know how it goes, thanks.
No problem, keep me updated. Thanks.
