Have you tried draining and refilling the system?..wondering if you have an airlock or even a failing water pump?..or thermostat?..Have you checked the electrical connections?.
Have you taken the hoses off?..
I recently changed my coolant,mine's an R too,and filled it with tap water and let if heat up/open the system a few times then used the correct coolant..
