Ok Chris, here it comes. I obviously have seen this post and now I will tell you what I am pretty sure is going on. You said you smell coolant, check for coolant on the passenger side floorboard under the carpet. I bet your heater core is leaking and that is the coolant smell you are smelling. When you have a leak in the cooling system anywhere not only does it allow coolant to leak but it also allows air to enter the cooling system which becomes an air pocket that can get trapped and cause your gauge to not read correctly. So your fix is going to be for you to change out the leaky heater core and then purge the cooling system of any air pockets and both your problems will be fixed. There you have it, nothing too horrifying though. /forums/images/graemlins/thumb.gif
