Another problem I see is with thermostats, aftermarket don't work like OE lots of times, Chrysler is bad for this.

Have you noticed that there are two lines of almost everything now. There is a t stat for 6.95 or another for 15.90. There is a significant difference in them.

I usually swap out Denso double platinum's in Chryslers without any issues and extend the 30k recommendation on the tune-up... Maybe I'm just lucky so far...

I do generally stick to motorcraft for Ford, Delco for GM, and Denso for asians. Whatever WorldPac recommends for the Euro's is what they usually get

This is how I've always understood it. They SAY they have the correct heat rating on the box but are truly not up to OE specification in that regard.
