Didn’t inherit my dad’s mechanical ability, so how do I add coolant if it’s been run dry (or possibly has a slow leak)? It’s my kid’s so not sure how long it has been empty and it has been running hot lately. Just trying to confirm if I add coolant to the radiator directly, to the reservoir or to both? And how much?

Hi,

When the engine is cold, remove the radiator cap and inspect level. If it is low in the radiator, top it off with a 50/50 mix of coolant and water.

Next, inspect the level in the overflow reservoir. There should be an indicator on it which says full. Fill to that point.

If there is a leak, you really need to find it. Here are a couple links you may find helpful:

Here are the directions straight from the repair manual. The attached pic correlates with this. I circled the two locations for filling.

Remove radiator pressure cap and fill system, using a 50/50 mix of Mopar Antifreeze/Coolant, 5 Year/100,000 Mile Formula and distilled water.

Continue filling system until full. Be careful not to spill coolant on drive belts or the generator.

Fill coolant recovery/reserve container to at least the MAX mark with 50/50 solution. It may be necessary to add coolant to the recovery/reserve container after three or four warm up/cool down cycles to maintain coolant level between the MAX and MIN mark. This will allow trapped air to be removed from the system.

Take care,
