I disagree. The cost for flush and test is close to the cost for a new
one. Wouldn't hurt to try to clean it and then order a new if that fails.
I tried to get my Suburban radiator services a couple of years agao, and was
quoted 187.00. I could get a new one for 213.00. Used to be around 50-60
for a radiator flush, test, and reinstall. Personally, if I could source a
new on for the 150.00 quoted previously, I would go that route and save the
time. This is a 20+ year old part after all. Just my .02. no need to agree
with me...my wife nver does. :-)
