By eHow Cars Editor Replacing a leaking radiator hose can be easy and quite painless on most cars. Check that both ends of the leaking hose are easily accessed before attempting this repair, because on some cars the hoses are tightly tucked away and this job might be better left to a professional. == == == == == == == == Difficulty: Challenging Step1 Turn off the engine as soon as you suspect a leak, to prevent the engine from overheating. Step2 Determine which radiator hose is leaking and exactly where the leak is coming from by looking for wetness. Step3 Purchase 1 gallon of antifreeze and the correct replacement radiator hose from your local auto-parts store or dealer. (Radiator hoses are not interchangeable. They come in specific sizes and shapes for your particular car model.) Step4 Wait for the engine to cool down for at least 20 minutes, before beginning any work on the cooling system. Step5 Place a large pan or wide bucket on the ground under the hose to catch the coolant. Step6 Use a screwdriver to loosen the hose clamps at both ends of the hose you are replacing. Step7 Remove the radiator hose by twisting and pulling where it connects to the radiator and engine. If the hose won't budge, use a utility knife to cut it off the fittings. Step8 Remove the hose clamps from the old radiator hose and slide them onto the new hose. Step9 Put the new radiator hose on. Spray the inside of the hose ends with WD-40 if the hose is hard to get on. Tighten the hose clamps. Step10 Refill the radiator and the coolant reservoir with a 50-50 mixture of water and antifreeze. Step11 "Burp the cooling system" by running the engine with the radiator cap off until the engine warms up. Keep the engine running until both the upper and lower radiator hoses feel warm (this indicates that the thermostat is open and the coolant is flowing through the entire system). Burping the cooling system allows any air bubbles to escape. Add coolant to the radiator as needed. Step12 Look for leaks. Inspect around the hose clamps for dampness. Tighten the hose clamps if there is any wetness. Step13 Put the radiator cap back on. Step14 Check the coolant level after driving, to ensure there are no leaks. · If the leak is coming from around the clamp holding on the hose end, tighten the clamp with a screwdriver. This may be all you need to do if a loose clamp is causing the leak. · In a pinch, you can add either plain water or pure antifreeze if that's all you have, but your cooling system normally uses a mixture of 1/2 antifreeze and 1/2 water. · Never open the radiator cap or loosen a radiator hose clamp when the engine is warm or hot. The coolant could spray out and burn you. · Dispose of used coolant properly. Bring it to a repair shop or parts store for recycling. Do not pour it down the sink or into the gutter.

1992 delta 88 royal 3.8v6 you need to buy a radiator how do you tell if your radiator has a engine oil cooler on it so you can get the right radiator?

radiators are used as transmission coolers (typically) and only on automatic transmissions. you will have two metal oil cooler lines that go from the trans to one of the side tanks of the radiator. if you indeed have an engine oil cooler (on newer cars and trucks) you will have an add'tl two lines that go from the engine block (usually at a oil filter adapter housing) to the other radiator tank. if you have a standard trans and still have cooler lines going to the radiator its for engine oil. some but not many vehicles use the engine oil cooler as a total separate cooler usually mounted in various locations around the radiator and it will be smaller.

2000 Pontiac grand prix and the transmission oil is milky in color and the oil level continues to increased and the transmission slips?

The reason the fluid is a milky color is that water is getting into the transmission. How you ask??? Well the cooling lines go into the radiator to cool the fluid. It is at that spot it is picking up water as the cooler inside the radiator has a leak. the best solution would be to change the radiator. You could block the fitting ports for the lines at the radiator and put an external cooler on it. YOU MUST thoroughly flush the transmission and change the fluid and filter.
