The water pump is in the back of the motor on this one, it requires a special socket to remove and replace. If you have been scratching your head on this one, Cadillac had head gasket bolt issues, the bolts stretch and the gasket leaks internally.

At least your honest, lol. When the t-stat was changed did you turn the heater on high and let the system warm up? It could still have an air bubble. Is there any discolored smoke from the exhaust system? How hot has the system climbed?

Upper fill panel, if equipped
AIR injection control valve, if equipped
Air cleaner
Oil level indicator tube nut, if necessary
Water pump belt cover
Water pump drive belt
Lower radiator hose
Thermostat bypass hose from the coolant inlet housing
Water pump cover

4. Remove the water pump by rotating it clockwise using special Tool J 38816-1A (water pump remover/installer).

To install:

1. Install the water pump with a new O-ring, by turning it counterclockwise using the special tool, until it stops. Torque the water pump to 73 ft. lbs. (100 Nm).

Hope this helps (remember to rate this comments)

the low oil pressure light can be a faulty oil pressure sensor.But mostly its the pump itself. open the oil pan and check if the net is chocked if not then replace the oil pump and do install the new o ring supplied with the pump. And try changing the oil on time and a good brand is important. (if the problem still exists then u need to replace the crank barring and the cam bushings..Just kidding).

There's a few things I'd take into consideration. As stated in other posts, yes make sure transmission fluid is up to proper level. Also, depending on what engine you have, there may be an electric assist pump or even 2 in the system. On some, they have an electric pump to circulate coolant through heater core at idle to maintain proper heat , as well as another to assist mechanically driven pump when coolant temperature gets to approx 195F. Obviously when going up hills there is an added continuous load on engine, which will cause it to run hotter, thus I would expect that electric pump to be kicking in, and if not, may be the cause. Also the added load of climbing hills, creates added exhaust temperature, and if there is any restrictions, the results would be overheating. Quite often you may feel at least a little lack of power compared to what it used to be, or an increase in fuel consumption, or both when exhaust has a restriction. With that said, a weak water pump is also a possibility. Hope this sheds some light on what to pay attention to.

Its a major job to change them on these cars. lol Been there done that. The easiest way to tell you on here is for you to go to the parts store and buy a Haynes or Mitchel book which will cost you around $20 and make sure you get the book for your car. Its quite the process to change these. I don't mean to give you bad news but I have done several and it ain't fun.

When you disconnect a spark plug wire, do you get spark when you crank the engine over?
If so,
When you turn the key to the "run" position (do not crank) do you here the fuel pump run for 2 - 3 seconds?
Let me know.
Regards,

i remember trying this. if your water pump is faulty. while the engine is off, spin the radiator blade. if it spins, then your pump is out, if it stops immediately, (it has a cluth of sorts) it's ok. also use a lower degree thermostat, like 160 degrees, then it will open sooner.

car keep running hot
