Hi guys, long time no post. 98 GC ZJ 5.2L Laredo that runs hot. 3 radiators, head gaskets, countless t-stats and a water pump later the only thing different is my bank account. I changed out the water pump today and it just seems as though coolant isn't circulating. No heat, potentially blend door actuator, but a new symptom for an old problem. She just gets warmer and warmer until she spikes and overflows out of the coolant reservoir. Even worse under load. Doing a test after the pump replacement, all lines are hot. No leaks and rad cap is hot to the touch. I'm working on bleeding out the system but same issue different repair. Thoughts?
