How to Replace the Heater Hoses in a Geo Tracker
The heater hoses in your Geo Tracker are prime suspects if you have a coolant leak. Even if you don't have a leak, replacing any worn hoses before they have a chance to leak and damage the cooling system is a good idea. This replacement is relatively easy and requires little mechanical skill.

Drain the cooling system. Place a bucket directly underneath the drain plug of the radiator. Then, open the plug to allow the coolant to drain completely from the radiator. When finished, be sure to pour the old coolant into a sealable container, as coolant is extremely toxic to both people and pets.

Locate and loosen the clamps from the heater hoses. The heater hoses on a Geo Tracker are up near the windshield and connect the heater core to the engine. You will need pliers or a screwdriver to loosen the clamps depending on which type clamp were used in your Tracker.

Use a knife or another sharp object to cut away the hoses from the heater core and engine block. Be sure to slice lengthwise on the hoses and don't use too much downward pressure, which could damage the hose fittings. Also, never pull or twist on the hoses that connect to the heater core, as this action could damage the core.

Scrape away any leftover hose pieces or debris from the fittings. Then, smear a dab of gasket sealer on the fittings. This sealer ensures the hose connects to the fittings properly and securely.

5
Put the clamps on the new heater hoses and put the hoses on the fittings. Make certain you slide enough of the hose forward, so it won't come loose when you put the clamp on it.

Tighten the hose clamps into place. Next, refill the radiator with fresh coolant and turn on the ignition of the Geo Tracker.

7
Let it run for about 15 minutes. Be sure to check for any leaks from the heater hoses throughout this time. If you don't find any leaks, put the radiator cap back on, close the hood and clean up any mess.

Tips & Warnings
You may need to replace the hose clamps, as they can also deteriorate during the normal course of operation.
Never work on the heater hoses or the radiator when the engine is hot or warm. The heat from the engine will heat the coolant and burn you.
Don't put any gasket sealer inside the heater hose. Only use it on the fittings as this can cause a leak, if there's a loose connection.
