Hey everyone, I noticed a couple weeks ago my coolant reservoir on my 4.7 V8 was leaking a tiny bit. As far as i can tell it is probably coming from the cap (I am going to order one the second I post this thread). I attached a picture of what it looks like almost every time I drive using the heat. Should I start thinking about replacing the whole reservoir? Thanks for the help!


EDIT: I ended up getting the whole reservoir replaced. Total cost was $498. Labor was $190, the rest of the cost was in parts + Massachusetts tax. I got the reservoir, reservoir cap, thermostat housing, and thermostat replaced with mopar factory parts. I also got my old coolant flushed and had new Mopar Dodge coolant put in. Truck runs great, no worries now about "boiling coolant" or anything of that nature.

 

Replace the obvious first. Cap.

 

I just picked up the cap, gonna let my truck cool down and replace the cap after.
