I think it's on or near the top of the rad... there is no visible signs but when you run your hand over the top you can feel some steamy air rising. it's been like that for a while now so i'm gonna have to deal with it eventually.

still considering the diesel upgrade... drove a few yesterday, 2 dodge & 1 chevy... the chevy was beat and not worth it, one of the dodges was completly stock and was pretty weak. the other dodge had some work done to it and was pretty quick... quicker than my truck I think...[sm=confused06.gif]

 

still considering the desiel upgrade huh? dont leave us steve!!!!!!!! no !!!

 

Steve,

If that built up in two months, just think of what your water jackets look like inside the engine. I would say you should either take the truck in for a full force flush, or pull the rad and have it vatted at a shop. At least the radiator will have less sediment.

 

naa, that's how it looked 2 years ago and I was able to flush all of that gunk out no problem. as long as it stays full i'm ok. once it hardens, then i'll have a problem. when I flushed it back 2 years ago, a lot of gunk came out, then when I pulled it apart a year later after using distilled water, there was absolutely no sediment at all, it came out so clear, I would have re-used it if it werent for the new stuff sitting on the garage floor...

 

you are mixing that with coolant, right?

 

now i have to go flush mine again...

 

yeah well, a lot of times well water does that because of teh bacteria!

 

yup, mixing it with the orange 5 year stuff...

 

Are we supposed to use distilled water along with anti freeze? In other words, I flush and refill using regular water and prestone. Is that wrong?

thanks

 

yes you should use anti-freeze... 50/50 mix. I've never had a problem using the green stuff and tap water. For some reason the orange 5 year stuff creates this gunk in the tank & block that plugs everything up. 2 times now i've seen this.
