Last week my jeep started over heating, all my fluids are good, I replaced the water pump less than a year ago, I replaced the thermostat less than 2 months ago, I just bought a new radiator and installed it today and its still over heating. It doesnt over heat all at once but just slowly creeps up until it gets into the red, it heats up the same rate no matter weather im idling or driving.

FAN CLUTCH--NOT WORKING RIGHT?

RADIATOR HOSES SQUISHY AND SUCKING FLAT?

THERMOSTAT IN CORRECTLY?---SPRING DOWN--POINTY SIDE UP?

NEW PARTS CAN BE BAD!

BAD SENDER OR GAUGE---CAN YOU TELL IT'S OVERHEATING?

The initial overheating can lead to subsequent internal engine damage. This engine is very notorious for cracking the head or blowing a head gasket when overheated. It needs to be pressure tested, compression tested and chemical tested to determine if this is the case or not.

@CJ MEDEVAC
Radiator hoses are fine, and the thermostat is in right, I can tell its overheating because the the gauge says it is and then sometimes the overflow overflows.

As for the fan clutch im not 100% if its working right, I cant get it to kick on in idle but if I drive it around the block it'll kick on.

@Wrenchtech
i can get it pressure tested at any mechanic shop right? Or is there something I can do at home for this?

You can do it at home if you have a pressure tester and you know how to thoroughly inspect for ay leaks or seepage. You may need more than pressures tests though if they aren't definitive enough.
