I noticed that my coolant seems to be leaking in my 2006 Kia Sedona, so I went out and got a pressure tester to see if I could troubleshoot it myself. I’ve got a Kia adapter, and it seems to fit the radiator cap fine, but when I pump, it bubbles up in my coolant reservoir and doesn’t build any pressure. Is this indicative of a problem or am I doing something wrong?
Pinch off the hose to the coolant reservior and try pressure testing the cooling system again.
Tester
Simple enough fix, I feel dumb for not trying it. It did the trick, though the tester had a bad seal. Should have read the reviews first. Harbor Freight may not be the way to go.
