Intepid with a 3.5 motor has been overheating off and on all year. It
has a new radiator,thermostat,pressure cap. It only seems to overheat
when it's cold out. all summer ran fine. Now it's starting to overheat
again. Some days can drive 200 miles and it's ok. Then the next day
drive it 5 miles and it gets hot. Have bleed the system many times. But
still seems like there might be an air pocket or something to make it
overheat. Can I use a lower pressure cap to to keep it from overheating
like you use to be able to do on older cars? Any ideas on this problem?
Thanks for any info.
