Hi, well 4 days into being a new owner and the main problem crops up. The plastic Thermostat is leaking from just about everywhere. Thanks to the forum for having a lot of discussions on coolant leeks! Now i've noticed a few places on the internet that a Aluminum thermostat body is available. I'm wondering if people have experience with those. Or do ya just go plastic and replace them more often? i got the truck for a good deal so i"m not worried spending a bit more on a part that will hopefully last longer. Any advice on the part?
