What happens when coolant leaks in a Nissan?

Widespread transmission failure in 2005-2010 Nissan SUVs and trucks can be traced to coolant leaks from busted radiators. The leaked coolant mixes with transmission fluid creating a toxic mixture, known as the “strawberry milkshake of death”, that destroys everything around it.

Why does the radiator cap keep coolant from boiling over?

The radiator cap allows the pressure to build inside the engine as the coolant heats up until it reaches about 15-16 pounds (a typical cap rating). Since pressurized fluid boils at a higher temperature than room temperature fluid, that allows the system to operate a higher temperatures without boiling over.

What happens when a hose breaks off a plastic radiator?

For example, plastic radiators are more prone to punctures from road debris and are more likely to have pieces break off, such as a hose connection. Hose connections on plastic radiators can crack and break, causing coolant to leak, which can expose the engine to potential overheating unless repaired swiftly.

What happens when radiator coolant leaks into transmission?

The Strawberry Milkshake of Death Ruptured radiator cooler tanks are forcing coolant into the five-speed automatic transmission through the cooler lines. Not only does the radiator stop cooling the transmission, but the resulting slurry of coolant and transmission fluid eats valves, erodes seals and speeds up corrosion.

What can cause a radiator hose to collapse?

In other cases a cooling system fault can cause the hose to collapse. In either case an inspection must be performed as a coolant hose that has collapsed cannot flow coolant properly. This can result in the vehicle overheating and engine damage. 5. Radiator hose is broken The radiator hose can be broken in a variety of different ways.

Where does the radiator hose attach to the engine?

The upper hose attaches from the top of the radiator to the top of the engine at the thermostat housing. The lower hose attaches from the bottom of the radiator to the water pump of the engine. If you suspect either radiator hose is failing, watch for the following symptoms:

What happens when radiator coolant goes bad in Nissan?

Not only does the radiator stop cooling the transmission, but the resulting slurry of coolant and transmission fluid eats valves, erodes seals and speeds up corrosion.

In October 2010, Nissan extended their radiator assembly warranty from 3 years / 36,000 miles to 8 years / 80,000 miles after reports from a “small percentage” of owners with internal cracks on the oil cooler tube. There was confusion about whether the radiatorwarranty extension covered resulting damage to the transmission.

What happens when coolant leaks in a pathfinder?

Leaking coolant is mixing with transmission fluid through the cooler lines to create a toxic hell stew that irreversibly damages everything around it. The widespread issue has prompted the North Carolina Consumers Council (NCCC), a consumer protection group, to pleadthat everyone avoid the 2005-2010 Frontier, Pathfinder, and Xterraat all costs.

Why is coolant leaking from my Nissan transmission?

Leaking coolant is mixing with transmission fluid through the cooler lines to create a toxic hell stew that irreversibly damages everything around it. Automatic transmissions in certain 2005-2010 Nissan SUVs and Trucks are under attack from their radiators.

Where is the coolant leak on a Nissan club?

First off, Stop Leak is the worst thing you can use for nissan coolent systems. Flush that stuff out right away, it clogs up the heater core!! Anyway about your coolent leak, just by looking at the location on the picture, you see coolent down by the oil pan, most likly it is the water pump. The water pump is located in the timming cover area.

Why is my Nissan Pathfinder leaking coolant?

Leaking coolant is mixing with transmission fluid through the cooler lines to create a toxic hell stew that irreversibly damages everything around it. The widespread issue has prompted the North Carolina Consumers Council (NCCC), a consumer protection group, to plead that everyone avoid the 2005-2010 Frontier, Pathfinder, and Xterra at all costs.

What’s the worst thing to do with a coolant leak?

Mine is a 96 Maxima GLE w/ about 75K miles. First off, Stop Leak is the worst thing you can use for nissan coolent systems. Flush that stuff out right away, it clogs up the heater core!!

What should I do if I have a coolant leak?

So, that hose will travel from the motor back to the firewall or the rear of the engine bay. Overtime, due to heat and age, the ends of those hoses can become brittle and begin to crack where they are attached causing small leaks. In this case, the best thing to do is purchase a new hose and clamps and replace the broken hose.

Are there any recalls on the Nissan radiators?

The key to the petition was proving a safety defect existed, something Nissan has continually denied. NHTSA only forces automakers to issue recalls when there’s a safety risk involved. NHTSA found that the radiators are defective without a doubt. ” When examined under a microscope, cracks and fractures were observed at the lead points.

What causes coolant to leak from the intake manifold?

When these gaskets fail coolant will enter the crankcase or intake port, or drip down the outside of the engine. Intake manifold gaskets on many general engine models are made from plastic, and typically fail between 50,000 and 80,000 miles. A series of hoses connect the manifold with other engine parts.

Can a cracked head gasket cause a coolant leak?

Add sealer to the cooling system in an attempt to plug the leak temporarily, but arrange for the head gasket to be replaced in the meantime. A cracked engine block can cause internal coolant leaks, which will often dilute the oil on the cylinder walls and damage piston and rings.

Where does the coolant leak come from on a Nissan?

The tube appears to be some kind of water transfer tube running coolent from one side of the engine block to the other. This coolent tube is directly over the oil pan and displays a leak which appears to be coming from between the A/C and alternator. Do you know what this tube is? why it may be leaking? how to repair it?

5 Causes of Antifreeze Leaking. If you detect antifreeze leaking from the engine of your car, the wise move is to get it taken care of as soon as possible. A 50/50 mixture of antifreeze and distilled water flows around the engine during use, keeping it from overheating, so a leak can mean trouble.

What to do if your car’s coolant is leaking?

If the oil looks ok, the next step would be to pressurize the coolant system, remove the spark plugs and see if coolant is entering into one of the cylinders. Unfortunately the coolant leak might also be temperature dependent and it may take some time to find it, some leak hot, some leak cold and some leak warm.

Can a car lose antifreeze without a leak?

Monitoring its level and condition is a part of the regular maintenance of the vehicle. Generally, there should be a leak somewhat if the vehicle is losing a high amount of antifreeze.
