good evening my name is ***** ***** I will assist

did he change the thermostat??? it sounds like the issue. air i the system will also do this.

lastly, you may have damaged a head gasket allowing compression into the cooling system. a cylinder leak down test will confirm this.

what exactly was done in the repair??

Hi roy. They fixed the radiator and the main hose. Theres another problem when i bought the van. It did not come with a thermostat.? He said it was no problem . so does my van need one ?
Expert:  roybelding replied 1 year ago.

absolutely it needs a thermostat. it regulates the circulation all around the motor. by not having the thermostat, there are areas of the motor that dont get circulation and that will cause issues.

I would have it installed and then re check the system operation.
