Overheating

Asked by Juan Oct 24, 2018 at 10:44 PM about the 2003 Jeep Grand Cherokee Limited

Question type: Maintenance & Repair

I have a 03 jeep grand cherokee limited 4.7L not H/O. The
car doesn't overheat when driving but when i come to a
stop light or a standstill the car starts to overheat and the
upper and lower radiator hoses swell up.I changed the
water pump, upper and lower radiator are new, new
thermostat and housing, new coolant recovery tank. I heard
on some forms that there's a fan relay under the passenger
headlight, looked and it's not where people say i would be.
Need help Please

Try bleeding air from system like this remove cap from overflow tank fill with antifreeze to full mark leave cap off and start vehicle and let idle you will notice level in tank start to rise this is normal once thermostat starts to open level in tank will drop add more antifreeze to full mark then put cap back on.
