The cooling hoses used in your vehicle are subjected to both high and low temperatures as well as changes in pressure. For this reason, it is important to check the condition of cooling hoses regularly, and replace those that appear to be weakening.
Whenever the hoses are being checked, make sure there is adequate enough light to see all the hoses. This includes upper and lower hoses. Visually inspect each hose for signs of swelling, cracks or frayed ends due to weak clamps. If the engine is sufficiently cool, put your hand around each hose and squeeze. The hose should be firm. In the event the hose is soft, swollen, cracked of frayed, replace that length of hose.
REMOVAL & INSTALLATION
Make sure the engine is cool, and any system pressure has been reduced.
- Remove radiator cap, to relieve any pressure.
- Open the hood and cover the fenders to protect them from scratches.
- Disconnect the negative (ground) cable at the battery.
- Place a suitable drain pan under the cooling system hose that is to be replaced to catch any fluid that may come out. Always dispose of any waste fluid properly.
- Loosen any clamps which are holding the hose in place.
- Using a back and forth motion, slowly begin removing the hose. Take your time. Some hoses are harder to remove than others.
- Remove the hose. Clean fittings or ends that the new hose will attach to. Check to make sure the new and old hose are alike.
- Moisten interior edges of new hose with anti-freeze to help installation. Slowly insert hose over ends, working back and forth until secure.
- Install clamps and tighten. Add anti-freeze to radiator. Leave cap off.
- Install Negative battery cable.
- Start engine, allow to run for 10 to 15 minutes. If antifreeze level falls, add more fluid. Once level has stabilized, install cap. Check for leaks.
