Re: `98 TJ Still Overheating

How does one know if coolant is DexCool or Zerex G-05? Can't seem to
find either reference on a bottle.

Re: `98 TJ Still Overheating
 

Sorry dude- fan clutch seems fine. Mild resistance at cold startup,
once engine is warm and cut off, fan stops too.

How does one know if coolant is DexCool or Zerex G-05? Can't seem to
find either reference on a bottle.

Re: `98 TJ Still Overheating
 

Valvoline clearly labels its Zerex brand coolants in large letters on the
front label and as it is the only supplier of G-05 you most likely haven't
got it. Visually it comes in a gold colored jug and is pale yellow in
color.

http://www.valvoline.com/pages/produ...asp?product=10

If you want the old style American Green Zerex now calls it Original Formula
and it comes in a white jug.


If the label says Prestone or Peak it is DexCool or based on DexCool.

FWIW: I found Zerex G-05 at PepBoys
