You are correct. Overheating is when the car actually overheats (is in the red). My post says nothing about 215 being overheating. I’m not trying to be mean but please read my post before responding to it. My concern is that A, it always sat dead on 210 before it overheated so, why isn’t it now? And B it sat at 215-220 on a cool day, I think it’ll rise on another hot day like the day it overheated as in FULL red. I’m asking for people’s ideas on the problem seeing as it seems the waterpump fixed my overheating but it hasn’t fully gone back to normal.
I appreciate your link but I do not need to replace my radiator. It has already been replaced. Also, I don’t need a kit to replace a radiator. They have a petcock on them to drain them and a funnel is like $5 bucks at any auto part store. No need for a kit.
As far as drilling the little holt in the thermostat. I usually do but I didn’t have a drill or drill bit around at the time.
If the radiator is not leaking likely it is fine, however if it isn't a mopar replacement the cooling capacity is unknown to us on the board.
With regards to the funnel "kit" to each his own, but the nice thing about that "kit" of funnel and various seals is it allows you to put a volume of antifreeze above your radiator fill hole, it seals off so the burping bubbles, expansion and so forth does not result in spills. I don't think any decent mechanic (most folks on this board) NEED it but it sure makes it quicker, nicer, and less messy. The real benefit (to me anyway) is that it has a plunger to seal the funnel when the cooling system has taken all it can and allows the user to seal the reservoir (funnel) and remove from the radiator without spilling.
The lack of the hole and likely no jiggler in your thermostat may be the issue. Over the years of owning mine I have purchased two of the recommended stant thermostats and neither had a hole, however, I drilled both so I cant confirm that the lack of a hole causes the issue you are having, just sharing my experiences and trying to help.
