2006 Dodge Magnum Q&A
2006 Dodge Magnum Question: my car is overheating
I'm afraid you may have a blown head gasket. Is the check engine light on? Have you pulled any spark plugs to see if they are wet or smell like coolant? - Visitor
a cylinder leak down test will confirm a blown head gasket. a shop can do that for you and then move on. did you change the thermostat?? roy - mastertech6371
Roy is right about doing a cylinder leakage test to look for a blown head gasket. A simple test that is pretty accurate to verify a blown head gasket is a chemical test called a "block test". If fluid stays blue all is OK if chemical turns yellow carbon monoxide is present in the cooling system/head gasket is bad. - patrick mannion
Proper Cooling System Bleeding is imperative. Cooling system fill procedure is critical to overall cooling system performance. Close radiator draincock. Hand tighten only. Install engine block drain plugs, if removed. Coat the threads with Mopar® Thread Sealant with Teflon. WARNING: When installing drain hose to air bleed valve, route hose away from accessory drive belts, accessory drive pulleys, and electric cooling fan motors. Attach a 1.5 - 2 m (4 - 6 ft.) long 6.35 mm (1/4 inch.) ID clear hose to bleeder fitting Bleed Valve Location (2.7L): Located on the water outlet connector at the front of engine . Route hose away from the accessory drive belt, drive pulleys and electric cooling fan. Place the other end of hose into a clean container. The hose will prevent coolant from contacting the accessory drive belt when bleeding the system during the refilling operation. NOTE: It is imperative that the cooling system air bleed valve be opened before any coolant is added to the cooling system. Failure to open the bleed valve first will result in an incomplete fill of the system. Attach Tool 8195 , Filling Aid Funnel to pressure bottle filler neck. (The funnel is a Basic funnel with a separator in the down spout. You can make a separator using a piece of plastic). Using hose pinch-off pliers, pinch overflow hose that connects between the two chambers of the coolant bottle . Open bleed fitting. CAUTION: Do not mix coolants. If coolant is used other than specified, a reduction in corrosion protection will occur. Pour the antifreeze mixture into the larger section of Filling Aid Funnel (the smaller section of funnel is to allow air to escape). Slowly fill the cooling system until a steady stream of coolant flows from the hose attached to the bleed valve. Close the bleed valve and continue filling system to the top of the Tool 8195 , Filling Aid Funnel. Remove pinch-off pliers from overflow hose. Allow the coolant in Filling Funnel to drain into overflow chamber of the pressure bottle. Remove Tool 8195 , Filling Aid Funnel. Install cap on coolant pressure bottle. Remove hose from bleed valve. Start engine and run at 1500 - 2000 RPM for 30 minutes. NOTE: The engine cooling system will push any remaining air into the coolant bottle within about an hour of normal driving. As a result, a drop in coolant level in the pressure bottle may occur. If the engine cooling system overheats and pushes coolant into the overflow side of the coolant bottle, this coolant will be sucked back into the cooling system ONLY IF THE PRESSURE CAP IS LEFT ON THE BOTTLE. Removing the pressure cap breaks the vacuum path between the two bottle sections and the coolant will not return to cooling system. Shut off engine allow it to cool down for 30 minutes. This permits coolant to be drawn into the pressure chamber. With engine COLD, observe coolant level in pressure chamber. Coolant level should be within MIN and MAX marks. Adjust coolant level as necessary. - Johnny Mopar
check for blown head gasket mine did same thing found radiator fluid in #5 cly, - 65ssnova
I actually have a couple different lights coming on and off. my voltage light and my malfunction indicator light. can i really be having all of these problems at once. oh, and it's overheating. i o...
The first time the car overheated was in December. I had to add antifreeze to it. Then in February I was idling (but I did turn the car off twice) in Walgreens and it ran hot, but their was still...
My car ran hot one time Never had the problem before. I had it towed to the dealer. They said I needed $1400 in repair. Replace fan module, thermostat and gasket, oil cooler and sensor. I have neve...
New Thermostat New Gaskets New Radiator Worked fine for a couple months afterwards and then suddenly overheating again. History: Purchased in 2013. Worked fine during test drive. Worked fin...
it's only happened one time. i want to know if its a battery problem or an alternator problem
