Lower Radiator Hose Heater

High temperatures can cause trouble for motorists

 Heat can zap the life from batteries: While drivers cannot do much about the heat, they can make sure their battery is securely mounted in place to minimize vibration. They can also clean any corrosive build-up from the battery terminals and cable clamps, and ensure the clamps are tight enough that they will not move.  Keep your engine cool: Make sure the cooling system is flushed and the coolant replaced periodically as recommended by the vehicle manufacturer. Between flushes, make sure the coolant is filled to the proper levels by checking the overflow reservoir.

Inspect hoses and drive belts for cracking, loose or other signs of poor condition. Worn parts are more susceptible to failure in hot conditions and must be replaced.

Avoid excessive heat when the rubber meets the road: driving on underinflated tires can affect handling and braking of a vehicle, but it can also cause tires to overheat and increase the likelihood of an eruption. This problem becomes even more worrying when road temperatures are extremely high. Cars need fluids during extreme heat too: Drivers should check all vehicle fluids including motor oil, transmission fluid, power steering fluid and brake fluid to ensure they are filled to the appropriate levels. Fluids lubricate and serve as coolants by helping carry heat away from critical components. When fluid levels are low, this cooling effect is reduced, and the possibility of overheating increases.  Keep passengers cool: Maintaining a comfortable driving environment reduces fatigue, which can play an important part in driver alertness and vehicle safety.During the extreme summer heat, an air conditioning system functioning may be more than just a nice convenience.

The National Safety Council proposes measures to deal with an overheated vehicle when there is no help nearby. If your car overheats, do not drive more than a quarter of a mile. Towed to prevent further engine damage.

Pull to a safe place and turn off the engine. Do not open the hood until the vehicle is completely cooled or the temperature gauge has gone from hot to cold. Check the coolant in the radiator.Look in your owner's manual, if you do not know where the coolant reservoir is. Make sure the radiator cap is cool before opening. Slowly twist it off with a towel and be careful of any hot steam. If necessary, fill the coolant up the radiator.

2000 V8 LS Lower Radiator Hose blew - Lincoln vs Cadillac

My lower radiator hose cracked (blew) yesterday while wife was driving. See circled portion of photo where the plastic portion cracked. Car overheated. Got it home after letting it cool down. I found out this lower radiator hose (without the oil cooler lines) is a special item and not even stocked locally due to the special plastic middle portion that's about 12 inches long. I am currently chasing down a leak and going to pressure test the system tomorrow after work, but how did you first notice the leak? Overheated, popped hood and saw the crack? My leak is coming from in between the headlights, which I don't know how it could be coming from there seeing no coolant part runs between the headlights. I think it is running down something. Guess I will know for sure after the pressure test. I am currently chasing down a leak and going to pressure test the system tomorrow after work, but how did you first notice the leak?

In this latest case for my car it started overheating, I popped the hood saw coolant on top of the air cleaner. when I got it home to the garage I removed the air intake/air cleaner and saw the hard plastic tube section of the lower radiator hose had a hairline crack down the length of the tube (see red circled section of the hose in the 1st photo I posted).
