2000 Chevrolet Astro Q&A
2000 Chevrolet Astro Question: During Radiator flush I found suspected engine oil inside,mixed with cool fluid.
was the fluid brown or straw berry colored. could be trans fluid or oil depending on color - globalhelper
Trans. fluid and engine oil have coolers that run inside the rad. Prob. one of these is leaking into the rad. I dont think it is an engine problem!! - pushrod
