Hello I have a question about my 2010 Dodge Challenger with no heat. Can you please help me. It’s been 2 long winters with no heat. And I’ve tried everything. ---

Have you taken it to either a dealership or independent mechanic? ---

Yea I have a 2010 Dodge Challenger 3.6 L and I’ve been without heat for almost 2 winters. I’ve had the heater core replaced, a new thermostat, coolant flush, everything you can name. It’s not the blend door actuators or anything like that. The last shop I took it to told me it could be the engine oil cooler. I was just wondering was this an accurate assumption that the engine oil cooler may be the issue with the heat. I just don’t wanna waste another couple hundred at the shop and nothing’s fixed. ---

I cannot think of any scenario under which a bad oil cooler would affect your heat. ---

The return hose from the heater core goes to the oil cooler, if the coolant passage though the oil cooler is plugged, no coolant flow. I saw a few plugged oil coolers on 2006 to 2008 3.5 L engines when I worked at the dealer. Back then there was a service action to replace the coolant in certain 3.5 L and 6.1 L engines because of a supplier problem with the coolant, no anti-corrosion additive. The result of the bad coolant was a lot of aluminum flakes clogging the oil cooler. Your 2010 Dodge may have had poor quality coolant in the engine. ---

Thank you so much. So you think replacing the engine oil cooler may solve my heat problems? And what coolant do you recommend for the 3.6 L dodges. ---

hot coolant goes thru heater core and is cooled. and than it goes to oil cooler. and back into block? i would believe there is a bypass prior to this circuitous route. would be nice if you could put a temp probe on heater core in/out hoses. to see what temps were. even cool coolant from oil cooler feeding back to block will be warmed before it exits motor and goes into heater core. after 2 yrs, i would have removed oil cooler loop.
