How to Check for Cooling System Leaks in a Plymouth Voyager

The cooling system is an integral part of the Plymouth Voyager's operation and checking for leaks is necessary to keep it running properly. If you can catch a leak in the early stages before it does serious damage, it can save a great amount of headaches and repair bills. Checking for these leaks doesn't require an extensive knowledge of auto mechanics.

Instructions

1

Move the Plymouth Voyager from its regular parking space and check the ground beneath for signs of coolant leakage. Because the coolant is a brightly-colored liquid, most usually green or orange, it should be easy to spot. Be aware that not all coolant leaks make it to the ground, as the heat from the engine may burn up the coolant before it can reach the ground.

2

Open the hood, grab a flashlight and check every visible area on the radiator for leaks. Look for any fresh coolant, corrosion or discoloration, which are sure signs of leakage. Examine the underside of the radiator, as rock and road debris can damage it during normal operation of the Plymouth Voyager.

3

Check the water pump and its gasket seal for leaks. The water pump is between the engine and radiator, behind the engine fan. The gasket seal is what secures the water pump to the engine block. Examine both parts for leaking coolant, corrosion or discoloration.

4

Inspect the hoses that connect the radiator to the engine and the engine to the heater core. Because these hoses are plastic composites, they are susceptible to bulging, cracking and splitting. If you still can't spot the leak source, a pressure system check may be in order.

5

Remove the radiator cap and fill the Plymouth Voyager with fresh coolant until it's nearly overflowing. Be sure the radiator is cool to the touch before you remove the cap, as the internal pressure from the radiator can erupt and burn anyone in the vicinity.

6

Turn on the engine with the heater setting on high. Allow the van to run for about 15 minutes. Switch the engine of the Plymouth Voyager off and inspect the auto part from the previous steps again. If there still isn't any sign of a leak, it's most likely internal and you should see a cooling system specialist for more diagnostics.
