i replaced my sending unit to the gauge when I noticed one wire was pulled out of the plug. At the same time I had flushed my radiator (just with water. Left it running and kept the radiator full while it was running and draining at the same time) Also changed the cap and thermostat.
I have a factory spec 195 tstat from oreillys. Before I did all this the gauge would stay at 210 consistently when cruising hwy or city.
Originally, my ac went out and manifold pressure through the roof. I drained and refilled the system, put in a new fan clutch and all was fine there so I new the 210 after a new fan clutch seemed right.
After the new sending unit it hangs at 230 (next hash mark after 210?). I'm curious if the sending unit is off or it's really that hot? I took a temp gun and measured the coolant and the tstat housing. Both around 210 Is there any way to get a definite temp to reference my gauge too? I don't want it running hot.
It's a 95 4 banger with 190k miles on it. Radiator has been previously replaced before me and it's clean and clear. Seems the flow is just fine as well....
Any insight? I want to do an elec fan conversion but want to make sure it's currently running up to par before I go changing things.
