2004 Ford Crown Vic (non-police). There is a factory option for an add-on engine oil cooler. I live in Phoenix where air temps are well over 100 degrees for four months straight and roadway surface temps even hotter.
I do a little bit of stop/go freeway in the afternoon on the way home. Some local street driving to run errands. Mostly, though cruising at 70mph to/from work. Because of the heat here, I will often idle the engine to run the a/c when eating at a Sonic Drive-in or when hanging out with friends.
Is there a benefit to doing the add-on?
Would it cause more harm in the winter/cooler months?
I know the police Crown Vics it came standard (I have friends that have surplus police CV's) and they don't seem to have any problems using the cooler year round....at least here.
Thanks everyone!
I think your over thinking this problem or no problem at all. Oil coolers are there for a reason and that is to cool the oil from getting too hot and then become too thin. Those oil coolers keep the Crown Vic engine running when they are idling at the doughnut stands.
Your thinking their is a problem when their is not.
The 3.6 Pentstar engine is prone to ticking if idled for periods longer than hour constantly. I heard this is due to design of oil passage to the heads and oil temperature. Would an aftermarket cooler correct this. I would love to leave ac on more than 1/2 hour when waiting for a load to be dispatched. Thanks
I was mostly wording the experience I have on the 4.6L engine. If this "Ticking" is caused by high temperature then addling or even an extra oil cooler would help to keep temps down. I wonder if this ticking presents itself if the idle is higher than normal while car is still ? Another thought is to install an extra fan outside the radiator to cool the oil cooler as well.
