Hyundai XG350 Thermostat Problem
Thanx
Asked by HyundaiXg350LAnswer
we cannot see or touch it. what were the 3 opinions???
is the check engine light on??
why was the thermostat replaced originally???
did it overheat at any time???
Roy
The check engine light isn't on
the thermostat was replaced because occasionally the temp. gauge would fluctuate now it's ever single time i drive.
I believe its over heating, yes
first thing is get a leak down test done to verify that the head gaskets are not bad.
beyond that, sounds like air in the system but should have bled off by noe.
Roy
can i do a leak test myself or i have to go to a shop?
if you have tool to do the test, yes. it would be cheaper to have someone do it for you.
Roy
ok great
someone told me it may be my water pump and they are expensive
.
could that also be the problem?
not really no issues with impellers on these pumps.
start with the test first before assuming anything
