changed radiator 2 weeks ago to CFS 3 row. now jeep takes FOREVER to reach 190 and then stays there. but i just noticed that electric fan is spinning and spinning where it didn't used to spin at all except at 220? ideas? is my temp gauge shot?

 

I just replaced my oem radiator with the same CSF unit. My temp gauge hasn't reached 210 since installing the new CSF. As for the electric fan running....it will run at any temp, if you have the A/C or defroster on.

Do u have access to a infrared point-n-shoot temp gun? If so, verify temp at the t-stat housing. Are u running a 195 t-stat? Could be stuck open.

 

^x2 couldn't have said it better my self

 

my gauge tends to creep a little (about 220+when slow low uphill climbing..)and want to get it cooler..what is a csf?

 

Think it's the manufacture. Op how is the heat? You may have a air pocket in the system.

 

i run the stock radiator, with a 180 t-stat, with 1998 grand cherokee heavy duty fan clutch and aftermarket 12" electric fan (in place of my stock one). mine sits between 190 and 200 all day. even after/during hard wheelin it sits right at 200.

but for your 3 row, i would say unplug the electric fan and see if the temp has a more normal cycle.

 

ok, at the risk of sounding like a TOTAL newb...uh...what?...
