Ppl are strange why are you repeating my mistakes??
I told you, we replaced tstat, then water pump, then my Indy said WTF? he tested cooling pressure and it dropped which was indication of the leak. Coolant pipe is not only about loosing coolant it's about air in the system and poor circulation.
Btw check your electric pump located on driver side front rail near headlight. It's 99% dead bc even with air in the system it will help with heat in the cabin. Set blower on 90f and touch the pump it should be vibrating.
Did you try venting you system? Just set heater on high blower on low and with cold car run the engine on idle for 2-3 mins. If it doesn't help you have 100% my problem
Btw when we removed the valley pan my Indy found it was leaking on the back of the block bc 2 bolts were rusted.
