i know its just a ground thing

[killyoass]

so what does the temp sensor do if it dont run the gauge?????

[lesterl]

Its probably open if it doesnt work. Engine block ground to pin should have a reading http://i191.photobucket.com/albums/z...ensorchart.gif

I just find it hard to believe that none of the stores have it in their system, ya know? They keep telling me it's a coolant temperature sensor (#su109) but that's the one on the front, next to the radiator hose. This one has a different plug on the wire, and it fits the sensor.

I'm gonna try what Killyoass gave me today. Hopefully it works, since i'm driving it to RA in 2 weeks, lol.

ok so why is this truck rinning 265 degrees
changed the thermostat= nothing
were gonna take it out next see what that does

[lesterl]

Put an ohmmeter across the CTS and read what the coolant temp is, use the chart I posted to check it against the temp you think it is (265 would be very low, just a few ohms) (you should be seeing around 200 ohms on a warmed up engine.)

88 S10 2.5 radiator leaking

Here's the history of this truck since I've had it.
-oil pressure light came on during idle went off during higher rpms
-Valve cover gasket leaking
-radiator leaks when parked right after driving (leak at the top)
-changed oil to synthetic 10w40 high mileage oil light doesn't come on anymore
-slight tapping/knocking during idle
-180,000 miles

I assume that when oil is not being sent properly throughout the engine pressure builds up in the engine and causes leaks in the valve cover and radiator. Now if I replace the radiator with a new one and replace the valve cover gasket, will my engine lock or blow up? Should I replace the oil pump before sealing the leaks?
Any comments will help. Thanks.
