I was getting ready to change out the fluids for winter when i noticed what looks like white chaulk inside my radiator and level was low. Anybody got any ideas what that is from and should i be worried??

 

Forgot to mention truck is 1987 f250 4x4 w/ 6.9.

 

Could that white chalk be oily........

 

maybe the mineral in the water your adding. The water was burned off and the menrals are left.

 

It could possibly be oily but it is very white not like when oil and water are mixed, but i really dont know. What does it mean if it is oily?

 

Have you checked your oil? If your oil level is high and also milky, you probably have a blown head gasket.

I checked the oil and it is not milky. It is also at the proper level. Is it possible that the good old well water out here on the farm could cause this? The temp doesnt seem to be unusual at all. Should i try to flush out some of the debris or will that cause more of a problem? Are there any prducts i can put in to clear this up?

 

Napa has a coolant system cleaner to clean the scale and Calcium deposits that you are seeing in your radiator. Or you can take it to a radiator shop and has the system flushed.. When adding water to your coolant system it should be distilled water to lesson the chances of mineral deposits building up....

 

Thanks to all of you who replied i will get to napa as soon as possible and buy some distilled water to put in w/ the anti freeze.


Thanks again,

Remember,diesel rated anti freeze,and dont forget the coolant additive.

 

I dont know what you mean by additive but i do know about diesel rated anti freeze, can you explain?

 

Search for cavatation

 

You should use an additive in the coolant to prevent "cavitation". Do a search on it. There have been quite a few threads on it. You can buy the additive at Ford for about $7 a bottle. You will probably need two. Follow the instructions. And buy some test strips at a place like NAPA. Check the coolant regularly. Good luck with it.

 

Are you are getting your engine flushed or doing it yourself the "Book" states remove the tstat to allow complete flushing at higher flow levels to remove deposits.Removing and installing a new tstat is a good 2-3 hour job..........

Never Never Never use tap water unless it is an emergency, always use deminiralized/distilled water.

 

What is this about diesel rated antifreeze? My truck runs right on the "r" when I'm getting on freeway it rises to "m-a" or towing dump runs on "m" could this be caused by wrong antifreeze? it has additive.
