Temp gauge creeping up in traffic, is my radiator on the way out?
Quote from Yasmin Penrose on September 17, 2026, 6:52 amNoticed something weird on my 2015 Grand Cherokee last week. Was stuck in that brutal afternoon traffic near Al Zahiyah and the temp gauge started climbing past its usual spot, not into the red but close enough that I turned the AC off and cranked the heater just to be safe. It dropped back down once I got moving, but now I'm paranoid every time I stop at a light. Coolant level looks fine, no puddles under the car, and the fan seems to kick on, so I'm not sure if it's a clogged radiator, a weak water pump, or just the UAE heat doing its thing. I started asking around and someone mentioned a top Jeep radiator specialist in Abu Dhabi that actually pressure tests and flow tests instead of just throwing parts at it, which sounds way better than the guesswork I've been doing. Before I book anything though, has anyone here dealt with intermittent overheating on a Jeep? Did a flush fix it or did you end up replacing the radiator? Also curious if a worn radiator cap can cause this because mine looks original and kinda crusty.
