The heater quit working in Joy & Matt’s 2005 Dodge Caravan. Scheduled to bring their van in for routine maintenance, our auto mechanic found in his inspection that the radiator was actually leaking. Though there was no evidence of the 2005 Dodge Caravan overheating, the radiator lost just enough water to cause the heater to quit working.
Undetected radiator leaks are common especially in radiators with plastic tanks. The leaks begin at the radiator seam due to the heat and pressure in the cooling system. The pressure builds over time and weakens the seam between the radiator tank and radiator core causing the seams to loosen, causing leaks. Once the radiator is low on fluid the heater will quit working due to low flow of fluid into the heater core. The heater core is a radiator type part located under the right side of the dashboard. It is incased in a plastic housing and cannot be seen from inside the vehicle. It heats up when coolant from the engine travels in and out of the heater core through two small hoses attached to the cooling system of the engine. As the engine warms up the coolant heats up and a small fan pulls air through the warmed up heater core providing the heat to warm the inside of the vehicle.
Thanks to Joy and Matt’s little girl, there family was Val & Mike’s Auto Repair’s “Big” contest winner for the quarter! While waiting with her Mom and brothers last August at Val & Mike’s while their van’s oil was being changed, she played our Newsletter Contest Search and she found all the hidden wooden trucks. Their entry was picked and her Mom and Dad won a FREE oil and filter change, tire rotation, brake check, battery test and 32 Point Inspection. She was very excited about winning especially something her Mom and Dad! And she is soooo cute!
