My car overheated. Coolant was visible on the engine, but I did not see any busted hoses. I think it could possible be the thermostat or the radiator fan.
If you’re seeing coolant, there is a leak somewhere. Coolant leaks can originate from many places other than the hoses. This includes the engine, water pump, etc. A pressure test of the cooling system using dedicated equipment will reveal where the leak is coming from. When a vehicle overheats, major engine damage can result. I suggest you have a trained technician, such as one from YourMechanic, diagnose and repair your vehicle as soon as possible.

They happen when the hose either deteriorates due to heat or abrasive damage, or when there`s a problem with the clamps that connect the hose to another component in the engine. If a radiator hose is leaking, there are a few signs to look for: A pool of fluid under the car when it`s been parked.
If you allow a leak to persist in your engine`s cooling system, you will eventually get a low coolant level in your vehicle. Low coolant levels can lead to improper cooling simply due to the lack of cooling in your system which can lead to boiling in the engine block, and hot spots where coolant no longer reaches.
You most likely have a blown head gasket and the coolant is leaking into the combustion chamber(s), where it is getting past the rings into the oil as well as going out the exhaust. Sometimes the block gets warped from this leakage and has to be re-honed and decked (flattened) or replaced altogether.
A Honda Accord`s coolant leak is most commonly caused by loose hose connections, a broken radiator, or a failed water pump. With time, sediment and rust accumulate in radiators, hoses, and hose connections, leaving holes in the radiators. Accords can overheat or run hot if they leak enough coolant.
Coolant is used to remove heat from the engine by transferring heat through a series of coils. The cool air then flows back into the engine, preventing the engine from overheating. It`s best to avoid driving your car if you have a coolant leak because an overheating engine is an unsafe engine!
The most common failure mode on a standard, moulded hose is electrochemical degradation, or ECD. ECD is caused by an electrical charge being carried through the coolant from component to component. It occurs because the hose, liquid coolant and the engine/radiator fittings form a galvanic cell or “battery”.
Stop leak products are designed to seal leaks in radiators, coolant hoses and gaskets by plugging them with some type of material. They usually come in bottles that you pour directly into the radiator (wait until your engine is cool to open the radiator, of course).
A cracked engine block can cause a range of problems. Ultimately, since the circulation system that cools the engine is comparatively fragile, a cracked engine block will lead to coolant leaking out of the area it is needed and leaving the engine to overheat.
The best way to confirm the source of the leak is to wash the radiator and hoses with water, and then start the engine and look for new signs of coolant.
It may be a broken hose and/or a hole in the radiator. Solution: Check your hoses to see if any coolant is coming out. Replace the hose(s) if you notice coolant coming out of them. If you notice coolant leaking out of your thermostat that can be an easy fix.
When intake manifold gaskets become damaged, coolant may begin escaping from its system. Eventually even a relatively small leak will eventually cause coolant levels to drop to dangerous levels. Be sure to take note of any signs that your car may be experiencing a coolant leak.
Corrosion within the radiator is one of the leading reasons that coolant leaks. As the tubes get older and weaker, you may get sediment or debris inside that causes a leak. The sealing gasket between the tank and the radiator can also wear out, and that could lead to a leak.
Gaskets and Seals
One common place of a coolant leak is the radiator pan gasket. The drain plug can also cause leaking, and if the cap that seals the radiator can no longer contain the pressurized coolant, it will leak or spray out from underneath.
When Should I Replace My Radiator Hose? There is no set lifespan for a radiator hose. On average, they should last for at least five years, but some will last longer, especially if you`re vigilant about having your coolant changed and your vehicle maintained properly.
The most common coolant leaks occur in the hoses that connect your engine to your radiator or heater core, or other small hoses running coolant to different equipment on your engine.
Yellow – Yellow fluid indicates a radiator coolant leak, which can happen if there is a loose hose clamp or a damaged o-ring. This is vital to fix as soon as possible. Green – Green fluid can point to an antifreeze leak. Antifreeze can start to leak when certain hoses, fittings, or clamps have worn out.
Electrochemical degradation is a primary cause of most coolant hose failures. This phenomenon occurs when different kinds of metals in the cooling system generate an electrical charge, which is carried from one component to another by the coolant.
There is an easy way to find out if your engine`s head gasket has blown. Simply check under the oil filler cap. If the gasket is not damaged, the inside of the oil cap will be mostly dry. If you discover a milky brownish-yellow substance that is similar to the thickness of a milkshake, you probably have a gasket leak.
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.
Technically speaking yes you can use plain water in your cooling system but it isn`t recommended as a long term solution and certainly not in extreme weather conditions.
Why is my car overheating but it has coolant in it? It could be that the coolant concentration is not correct, or you may have a bad thermostat, a failed water pump, broken drive belt, or a bad radiator or radiator fan.
Sand ingestion would look like small beads to form on the hotter surfaces of the plug. But burned engine coolant leaves ashy, white deposits on the electrodes and insulator, creating hot spots that could cause pre-ignition and a misfire code to be set.
Broken radiator hose or hot pipe is easy to fix with Rescue tape because it can handle temperature up to 500F and pressure up to 950 PSI. | Rescue Tape is extremely durable, but when it comes time to remove it, it does not leave any sticky residue like a duck tape.
