What system? Engine Cooling or Air Conditioning?
Yes, the water pump can leak if you do a coolant flush.
Drain, flush, and refill.
It is not necessary to flush any system on a car. Brake fluid absorbs moisture from the air which in turn causes a corrosion to build in the system. That in turn will cause the cylinders to leak and not work properly.
There's a leak in the pipe.
There may have been some Bar's leak/stop leak added at one time. Flush system. If that's not the case and it's a milk shake consistency, then you could have a bad head gasket allowing oil into the coolant.
Find the leak and replace the hose/part that's leaking. It's a good time to flush your coolant system, too.
flush your entire coolant system including removing the block heater and flushing that out as well.sounds like you have a carbon deposit build up some where in your system
If you have a crack or leak of some kind in your engine block it is only a matter of time before it completely fails. Most block sealers are made to plug the leak from the inside but also in turn put deposits along the cooling channels of the engine. It is the same as a human having high cholesterol sooner or later an artery will clog and there will be critical results. If it is a leak that can be repaired I suggest address the problem ASAP. Then do an engine flush to get the junk out of the system. By the way in an emergency pour a shaker of black pepper in your radiator to plug the leak!
If your F-150 is running hot after adding stop leak, it could be due to a few reasons. Stop leak products can sometimes clog the cooling system, obstructing coolant flow and causing overheating. Additionally, if the stop leak was added to a system with existing issues, such as a failing water pump or a damaged radiator, those problems may be exacerbated. It's advisable to flush the cooling system and check for any underlying issues to prevent further damage.
Because you either have a leak or someone did it wrong.
Check for a leak at the wax ring of the toilet. This leak will migrate out, on the surface or under the surface of the floor. Check for a leak in the wall in the back of the vanity (the vanity may have to be removed). A slow leak in a wall is likely to be the DWV system, not water.
I have never smelled coolant that smelled like fish. It usually smells sweet. I suggest you do a complete coolant system service. Drain, flush, replace thermostat, install a 50/50 mix of proper coolant and distilled water, bleed air from system.AnswerIt has gone bad and needs flushed and replaced! Hopefully that's all that wrong with itAnswerIt's good to flush the system, but the anti freeze is within the engine and internal heating circuit and should be sealed. Therefore if you can smell it you have a leak, so flush but also find the leak.
