2004 chrysler 300 3.5 literrunning hot
 

2004 Chrysler 300 with a 3.5 liter engine is running hot after around 25 to 30 minutes. new radiator new thermostat new water pump , flushed engine but still runs hot. no misfires no steam holds vacuum and hold pressure starting to think engine has partial blockage . if anyone has anything on this I would greatly appreciate it. Thanks

head gaskets are lots of problems on those engines.

Did you replace the radiator cap? If a cap is week, could be a cause.

Anyone do a combustion leak test?

found cap does have a groove cut into the rubber seal so gonna give a new cap a try hope it works. will let you know how it goes. thanks
