installing a upper radiator hose, on the engine side of the hose about an inch down the piece you slide the hose over has a raised lip, and another raised lip about 2 inches down, do i slide the hose over the first lip and stop at the second lip?
My car has 200000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello, thank you for writing in. Correct, you want to place the hose clamp between the two raised lips. If the hose will willfully go over the second lip, that is fine. The goal is to have the hose beyond the first lip, and have that lip there to give the clamp something to hold the hose on with. The second lip is to give an area for the hose to recede down into so the hose clamp can get a good grip. The longer the hose stays in place, the more the hose will form to the area giving you a good seal.

Your engine has two radiator hoses: an inlet hose, which takes the hot engine coolant from the engine and transports it to the radiator, and an outlet hose, which transports the engine coolant from the radiator to the engine.
Most vehicle cooling systems are comprised of four main hoses. The upper radiator hose is connected to the thermostat housing and to the radiator. From the bottom of the radiator, is the lower radiator hose that is directed to the water pump.
The most common cause for radiator hose collapse is a vacuum issue caused by a faulty radiator cap. Caps are rated around 14–16 psi. Under normal circumstances, caps should release the negative pressure caused when an engine cools down and the liquid coolant contracts.
Firmly squeeze both the upper radiator and heater hoses. They should feel firm, stiff, and rigid. A hose that feels very hard or makes a “crunch” when squeezed is an indication of age-related hardening or deterioration and should be replaced immediately. Oil is another enemy of rubber hoses.
The side of the radiator where the tubes connect should be at the bottom, and the pump should be mounted in a position where it is slightly lower than the top of the radiator, where air is captured. One good mounting position is to place the radiator at the top of the case with the tubes pointing downwards.
Keep in mind that the top hose is output from the engine and the bottom is the intake (counterflow system). So the bottom hose should be cooler than the top hose.
If a radiator hose can be squeezed, it only means there isn`t pressure in the cooling system, but this can indicate a problem. Cooling systems are designed to hold pressure. This raises the boiling point of the coolant so it can run above 212 degrees Fahrenheit.
The most common sizes of heater hose are 5/8″ and 3/4″. Inside a heater hose you can see the edges of the cords. Note the thin wall and sparse cord, this is low-pressure stuff. Radiator hoses are also lined with cords, but they are typically molded to shape to help prevent kinking and for better flow.
Replacing a radiator hose is a super easy job no matter what you drive! The only frustrating part of the job is trying to find a way to get to the clamps on the ends of the hose. Like any job the right tool always makes things easier!

I have to replace an upper radiator hose, what steps must I take to access the hose and remove it.
ANSWER : Access to the hose is clear. On a vehicle of this age, if you are replacing one radiator hose, really all should be replaced, including the heater hoses, due to the inevitable deterioration of rubber products. YourMechanic does perform radiator hose replacements on a mobile basis and so feel free to set up a mobile visit to have the hose(s) replaced. If you replace the hoses(s) yourself, be sure to use any available purge points to remove trapped air as you refill the cooling system. Trapped air can cause engine overheating until it dislodges.
Have a leak from upper or lower radiator hose.
ANSWER : I would recommend looking at either hose to determine which hose the leak is coming from with the car running as this will pressurize the system and force water to the leaking point. Consider scheduling an appointment with one of our expert mechanics to come to your home or office to diagnose the leaking coolant issue and make necessary repairs.
There’s a hose under the top radiator hose that seems to be leaking antifreeze. What hose is that and is it an easy fix?
ANSWER : Hi there. Usually the hose that’s directly under the top radiator hose is a return surge tank hose; typically coming from the radiator overflow coolant reservoir. Since winter is coming around soon, the best way to diagnose a coolant leak and to ensure it’s not your heater core of heater hose is to contact a professional mechanic and have them complete a coolant leak inspection. This service is the best way to eliminate the guess work and ensure you’re Chrysler 300 is repaired sooner rather than later.
Hi Steven, I have a 1995 pontiac grand am, quad4 16 valve. Today the upper radiator hose broke and I replaced it. The problem I am
ANSWER : There could be trapped air in the cooling system. The sensor could be dirty or defective or there could be a fault in the warning circuit. In some applications, there is a potential delay (documented in the Factory Service Manual) for the sensor to reset once you have completed the repair and refilled the cooling system. If there is no overheating, especially due to trapped air, and the cooling system is full (check when stone cold and check reserve tank, too, of course) and yet the warning light remains on for more than three days, the recommended service to get this resolved is a warning light diagnostic. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
overheating due to coolant loss with no leaking
ANSWER : Hi there. Completing a compression or pressure test might help diagnose the source of your problem, but I would suspect if you’re not finding a leak, that the issue is a blown head gasket. Two ways of determining if this is the case. First, check your engine oil. If the oil is milky, this means coolant is getting inside the engine oil galley’s some how, most likely due to a blown head gasket or cracked engine block. Second, check for signs of white smoke from the exhaust. This is also an indicator of coolant. Coolant has to go somewhere, and if you’re constantly running low on coolant and having consistent overheating problems; with no visible leak, the issue is probably internal.
I have an antifreeze leak internal I replaced the upper radiator hose new radiator as well can not see a leak or drip
ANSWER : Coolant leaks no matter how big or small should be addressed as soon as possible. As you noticed, the engine will run hot with a low coolant level. Even a minor leak can expand to a large or catastrophic leak with no warning. A minor repair now can turn into engine overheat and damage. The leak can be small enough now that it is burning away when contacting hot surfaces and not hitting the ground. If the radiator leaking is the cause of the coolant loss, then it should be replaced as soon as possible. The cooling system operates under pressure – usually 12-15 psi. A small leak can become a large leak because of the pressure. Have a certified technician address this as soon as possible. Do not use "coolant leak sealer" products as they are a temporary fix and can actually cause more damage by clogging small coolant passages and damage the water pump as well.
How to install the bottom radiator hose onto the radiator. It has a metal fitting and won’t stay on properly.
ANSWER : Hello. The lower hose has a twist lock that holds on the lower hose and the radiator outlet has two O-rings. Sometimes the hose will not lock well once removed and most mechanics recommend replacing the hose with a new one any time the hose needs to be disconnected. If you need help with the radiator hose installation, a technician from YourMechanic can assist or simply perform the installation for you.
