So I've been noticing any issue of my temperature gauge almost reaching the H segment while idling in traffic. It was reading at 116C+ (240F) on the ECT at these points. I took it into the shop, who replaced my radiator cap and thermostat but said that due to the heater core bypass, the coolant is not able to circulate. I opted to forego testing it with a new hose assembly as I'm assuming the heater core was bypassed due to failing/leaking (I bought it as is). The operating temperature now looks like it stays around 106C (222F) now (IAT 53C). Is this a normal thing with this bypass?
