How To Fix A RAM Coolant Leak

Coolant is crucial for keeping your RAM’s engine cool, but if you’ve noticed puddles of liquid under your truck or the temperature gauge rising, you might have a coolant leak. A coolant leak can lead to engine overheating, which, if left unchecked, can cause significant engine damage. Whether you’ve noticed the leak or suspect one, it’s essential to fix the issue as soon as possible. You can schedule a repair appointment here or follow this guide to help you identify and resolve a coolant leak in your RAM.

Identifying a Coolant Leak

1. Check for Coolant Puddles

• One of the most obvious signs of a coolant leak is the presence of bright green, orange, or pink fluid under your truck.
• The coolant might be leaking from various parts of your engine, radiator, or hoses.

2. Rising Temperature Gauge

• If your truck’s temperature gauge rises to the high or red zone, it’s a sign that the engine is overheating due to a lack of coolant.
• This could point to a slow or steady coolant leak.

3. Sweet Smell

• Coolant has a sweet smell, so if you notice this odor while driving, it’s a sign that coolant may be leaking.
• Pay attention to areas where you smell coolant—this could help pinpoint the leak’s location.

Common Causes of Coolant Leaks in RAM Trucks

1. Damaged Radiator

• Over time, the radiator can develop cracks or corrosion, leading to leaks.
• Radiator hoses can also become brittle and crack, causing coolant to leak from them.
• What to do:
• Inspect the radiator and hoses for visible cracks or damage.
• If you find a damaged hose or radiator, you’ll need to replace them.

2. Faulty Water Pump

• The water pump circulates coolant throughout the engine. If it’s leaking, it can cause coolant loss and overheating.
• What to do:
• Check the water pump for leaks, especially around the gasket.
• If the water pump is faulty, it should be replaced immediately to prevent further engine damage.

3. Leaking Heater Core

• The heater core is another potential source of coolant leaks. If you notice the windows fogging up, it could be a sign of coolant leaking into the cabin.
• What to do:
• Inspect the heater core for leaks inside the vehicle.
• A leaking heater core will likely require professional repair or replacement.

4. Blown Head Gasket

• A blown head gasket can cause coolant to leak into the engine cylinders or oil system.
• This is a serious issue that could lead to engine failure if not addressed promptly.
• What to do:
• If you see coolant in the oil (milky brown substance on the dipstick) or experience white smoke from the exhaust, the head gasket may be the problem.
• A blown head gasket usually requires professional repair and can be costly.

Fixing the Coolant Leak

If you’ve identified the source of the coolant leak, here’s what to do next:

• Replace damaged hoses or radiator – If a hose is cracked, replacing it is usually straightforward.
• Replace the water pump – A faulty pump should be replaced by a professional.
• Seal minor leaks – If you can identify a small leak in a hose, you can temporarily seal it with a coolant leak sealant, but it’s always best to replace the damaged part.
• Repair or replace the heater core – Heater core replacement can be tricky and might require professional assistance.
• Replace a blown head gasket – This repair is labor-intensive and often requires professional expertise.

If you suspect a coolant leak in your RAM, don’t wait for the issue to worsen. Schedule a repair appointment here to get your truck back on the road with no more overheating worries.
