What would cause the coolant and transmission fluid to combine and be visible in the overflow for coolant?
broken radiator
What causes coolant reservoir overflow or backup?
The radiator cap could be the cause of coolant reservoir overflow or backup. Have the cap checked to see if it is bad.
Why would the water in your radiator turn thick and yellow after overheating. This was both in the radiator and the overflow.?
The most likely cause of this is a blown head gasket dumping oil back into the coolant passages. The oil will mix with the glycol in the antifreeze and make a thick yellow paste. It is very important to flush the cooling system after the repair or this sludge will cause heating problems.
Will a Bad heater core in my 91 ford tempo cause the overflow and radiator to empty?
Only if the coolant is leaking from the heater core, but you will see this.
What would cause sludge build up in the radiator of a 1992 Pontiac Bonneville SSEi?
degradation of the coolant. flush the system and refill it, and all should be well.
What causes thick gray sludge in your radiator?
Thick gray sludge in the radiator can be caused by a buildup of corrosion, oil contamination, or a coolant leak mixing with debris. This sludge can block the radiator channels, leading to overheating and potential damage to the cooling system. It's important to flush the radiator and identify the root cause to prevent further issues.
Why would antifreeze level in overflow drop?
The antifreeze level in the overflow tank can drop due to several reasons, including coolant leaks in the system, evaporation over time, or a malfunctioning radiator cap that allows coolant to escape. Additionally, if the engine is overheating, it can cause the coolant to expand and push some out of the overflow. Regularly checking and maintaining the coolant level is essential to prevent engine overheating and damage.
What would cause sludge in the radiator and overflow on a 1994 Camaro 6 cylinder?
If you have the pink Dexcool antifreeze in it then that is the reason. You can go on the web and there are several class action lawsuits against General Motors concerning the issue.
What causes coolant to boil and overflow?
Engine coolant temperature is cooled by the radiator, moved by a water pump and controlled by a thermostat. If there are troubles with any of those components the coolant will boil Also if the head gasket goes bad gasses from combustion inside the engine will get into the coolant and cause it to boil.
Why are you losing coolant out of your overflow?
There could be several reasons. Under normal operation, the vehicle will experience this as the coolant heats up and expands into the over flow. A bad water pump, low level of coolant, as well as a clogged radiator could also cause this problem.
Why is 91 Honda accord ex coolant radiator is cracked?
If the radiator is cracked then the vehicle has ran dry on coolant. This would cause the radiator to crack if there wasn't any coolant.
What causes pressure to cooling system to force water into overflow reservoir?
Radiator pressure is caused by coolant expanding as it heats. The radiator cap allows that pressure to build until it reaches a certain point (determined by the manufacturer which is why it's important to use a proper cap for the vehicle) then a spring compresses and coolant is allowed past the cap seal. The coolant flows through a hose to the overflow tank. Now here's the magic part. Back in the day, before reservoir tanks, that excess coolant just fell to the ground, wasted. Now, with the tank, the liquid is actually drawn back into the radiator as the engine (and coolant) cool. The result, an always full radiator Cheers
