Since the thermostat is removed and assuming the water pump was installed correctly when you replaced it that does indicate that the problem is a blown head gasket, cracked head or Cracked cylinder wall causing over pressure in the cooling system or clogged coolant channels. The head gasket can be replaced, the head can be replaced unfortunately clogged coolant channels or a cracked cylinder wall mean engine replacement. In rare cases with clogged coolant channels you can have the motor acid dipped but due to cost you might as well purchase a short block and just replace it. One way to verify if it is to run the engine till it has warmed up and then pull the plugs and do a compression check. One or more cylinders will have extremely high compression from water being allowed into the cylinder. Water in the oil or oil in the water is just one indicator and doesn't always appear.

    It's not the cooling fans or switch. I can tell you from experience with a 2.4 cylinder in a Plymouth voyager I would look at the over pressure as being the problem. I had the same exact problem.

I would recommend that you flush the radiator with some Prestone radiator flush, and if that does not resolve the issue, I would recommend that you check the cooling fan, and the switch that activates the fan. If the fan is coming on as it should, then the switch is probably good, and you will want to replace the radiator.

There's a YouTube video at the link below showing replacement of the water pump and thermostat. It's lengthy, but at 29:40 and 30:18, it shows the cover bolted to the block. It should give you a pretty good idea of the orientation of the cover and the water pump.
According to information I found elsewhere, 1993-2001 is all the same.

yes,have suggestion.leaking coolant into the passeger side floorboard? film on the windsheild at anytime? suggest a bad heater core. or this,heater core stopped up.needs to be flushed.flush radiator with a common flush found at autozone,advance autoparts stores.or any other auto parts stores. remove your heater core hoses on the firewall[2 small hoses that go from the motor through the firewall to the heater core itself] flush the heater core there manually.push your water hose to the passenger side there and turn hose 'on' and watch the flow out the other side.[both hoses on the firewall will have to be off[or disconnected]to do this properly. your problems here,and since you've replaced the thermostats twice,suggest that this is your issue. thank you for choosing fixya.com
