The thermostat is located on the front of the engine under the upper radiator hose. Drain coolant remove the upper hose and remove two 15 mm bolts holding the thermostat housing on.

Removing the thermostat can in some cases cause the vehicle to run hot because then coolant is flowing to fast. Thermostat acts as a temperature regulator and is usually inexpensive. The water pump is located on the front of the engine and is connected to the cooling fan.

Remove the upper fan shroud six 10mm bolts. You need a special wrench to pull cooling fan off. Can buy at autoparts store. Once fan is off 4 15mm bolts hold water pump on. Remove bolts remove hoses. Make sure to clean gasket area off good. Gauges inop? If its more than one gauge acting up the clusters have a common issue.

coming from

No problem. You might want to pressure test the cooling system to determine source of leak.

Before I started saw 3 or 4 drops of oil on the ground
I drove it a short distance 2/3 miles up and back - and got the reoccurring
oil gage fluctuate from 40 to 20 as I stopped and go (went) the engine gage was low around 200 till I started to come back it went up to 210 which I believe is normal but I did not want to take any chances pulled over for a half an hour and then drove it home sat for an hour and

checked the oil dipstick was fine it seem that the oil had not dropped why does the oil gage indicate that it's going towards the left or towards the #20 from the #40

well the coolant level was fine which I believe means it's not the water pump so I went under the car looked for leaks saw the oil pan slightly moist which I thought it would be coming from the manifold the plug was dry so I grab a paper towel and wiped the pan it was oil and the sides to the right as you face up lying on your back; was slightly wet but could not reach it,
just a little not enough to hit the floor

where is the leak

The oil pressure gauge can go between 20 and 40 depending on temperature and engine rpm. 210 for the temp gauge is normal. You could clean off all the oil residue and put some leak dye in the oil to aid in finding the leak.

I'll try the pressure test to the cooling system to see where the leak is

thanks
