The coolant type is not the issue but It seems there is a LOW LEVEL OF the COOLANT. Allow the engine to cool down and check the coolant level in the overflow/reservoir tank. If low you need to top up the coolant in the tank. Also check the pressure cap of the radiator, replace if there is low level of coolant in the radiator.
However if the coolant looks murky or rusty then it is best to flush out the coolant and refill with the specified type.
You need what is called GO-5 coolant. It is a Chrysler HOAT coolant
manufactured by Zerex similar to the GM DEX-COOL coolant . It is a long
life coolant. The MOPAR long life product is orange in color.
this model uses any coolant that is marked Long life/Extended Life, all the coolant out there now are inbthis coolant class, of course the very best coolant to use is the factory coolant from the dealer.
Most serious item I see is oil pressure. Put a mechanical gauge on the engine and get an accurate reading. Also make sure that the passage to the sender isn't blocked. If you did the pump yourself, did you find any coolant in the oil? In 99% of all low oil pressure situations, the oil pump has not failed. Rather, either a cam bearing or crank/rod bearing is worn. You do not have to have one spun or completely worn out bearing. Even wear of all bearings that is somewhat excessive can bleed off enough pressure to cause problems (plastigage the engine bearings to determine wear). As far as coolant loss. A cylinder head gasket can fail between cylinders, into a water passage, into an oil passage or any combination of those and externally as well. The cylinder heads on engines beginning in about '98 are prone to "micro-cracking" which can lead to all kinds of hard to diagnose coolant loss problems. It may help if you have a shop do a dye test and a hydrocarbon test on the cooling system and see what they find. I have seen several kinds of block sealing systems available. Though I generally do not recommend them, as the longevity of the repair isn't predictable, you could try that as a option of last resort. There is no quick easy solution to your problem but with a bit of "poking around" you may be able to cure it. Don't bother repairing one problem before finding out what the other one is first though as together, it might be smarter to replace the engine.
