To stop a coolant leak with pepper, you can add finely ground black pepper to the radiator or coolant reservoir. The pepper particles can help seal small leaks by clogging the gaps as the coolant circulates through the system. However, this is a temporary fix and not a substitute for proper repairs, as it may not work on larger leaks or could lead to other issues in the cooling system. Always consult a professional for a permanent solution to coolant leaks.
yes, especially if the leak is causing coolant to leak, you can run out of coolant. then overheat.
If coolant leaks onto an engine it will cause no damage unless it leaks onto the alternator or into a wire harness connector of some sort. It is best to clean up leaked coolant as much as possible. It will smell a little when the motor is started. Leaked coolant on the ground is a danger to animals and children as it has a sweet smell but is very toxic.
Yes, coolant leaks can cause the temperature gauge to act erratically. When coolant levels drop due to a leak, the engine may overheat, leading to fluctuations in temperature readings. Additionally, air pockets can form in the cooling system, disrupting the flow of coolant and causing inconsistent temperature readings on the gauge. It's important to address coolant leaks promptly to maintain proper engine temperature and function.
it is probably your water pump
When it leaks. If it ain't broke don't mend it
You have a failed gasket, seal, or hose.
