I am curious. Today I noticed some white foam in my coolant tank, chillen on top of the coolant in the bottle. What could be causing it? Is this a sign of a cracked block or cylinder head? I have no idea what this could be. Anyone experience a similar problem. I am really hoping its nothing major, but the radiator and all the hoses were just replace about 6 months ago. Only thing not replaced was the water pump. Thanks fellas

White foam can mean that ur gasket is going and when the engine hits the combustion cycle it is also heating up and foaming the coolant. Could be a headgasket issue.

 

yepsounds like to me sir that youhave a blown head gasket...Pull the dipstick and if it looks like a milk shake...there's your problem.

 

New radiator or used?

First thing that comes to my mind is tranny cooler.

 

I would think that if the tranny cooler went, the fluid would be discolored....red and green mixed wouldn't be white foam.

I say check the oil, and maybe do another coolant flush to see if it comes back.

Get the engine up to full operating temp and then idle it while you watch the overflow line from the rad to the bottle. If it's blowing a fairly constant stream of bubbles in the overflow tank then you'ge got a popped gasket (or cracked head/block) for sure.

If not, you might just have some junk in the coolant (soap?) that can allow it to foam up.

 

Thanks fellas. The radiator is brand new. All the hoses are as well. I will look into it this week hen I drive her some more. Any other tell tale signs I should be looking for? The oil is a little low, but the color is just fine.

Then its your headgasket which is gone or starting to go so you are getting coolant and combustion together to make white foam

 

Thanks, that is more what I was thinking. Looks like its time for some major repairs!!!! Thanks fellas
