So I had a 05 wk with the 3.7 and had a heater core issue at 175k that I didn't know it was out of coolant, overheated killed the heads had them replaced, I recently had the overheating issue on my kk with a bad thermostat and have now noticed that when I first start up in morning I blow white/bluish smoke, just when starting when running its clean. no coolant in the oil, but I am loosing coolant somehow, carpet is competely dry no coolant smell with interior. Would anyone suggest that there could be a head issue on this one now? I am tired of sinking money into these 3.7's

If you ran it hot chances are god that you cooked one of the heads
Its not just 3.7 heads, its any of them anymore, run them hot and you'll have issues sooner or later

Yea that's what I was afraid of. When I bought it over the summer it came with a 12 month 12,000 mile warranty, I just hit 12500 miles since I bought it, I am going to try to see if the place I bought it from will still be honoring the warranty since the thermostat incident occurred a little over a month ago
