Owner reviews for thermostat

Swapped to mahle and it's good to go.

I work at a Honda dealership in the mechanic field, and I would recommend the OEM thermostat, unless you have a rebuilt engine.

Man, you just get the thermostat itself. Nothing more. Something like that was for 2008 Rabbit (2.5 I-5). Mine car had exactly same symptoms. It would reach 70 C and maybe at some point 80, but had tendency to stay cool (below 80) when driving. I know thermostat opens at 80 C, so anything below 80 is not quite right.

I got the GATES 34710 Thermostat. I haven't had any problems since replacing it 3 years ago.

Stop using cheap thermostats. Get an oem honda unit and it will last and work correctly.

Your temp gauge is reading low because your mechanic is not using an OEM Honda thermostat. An OEM thermostat is designed specifically for your engine and the car will warm up quickly and the temp gauge will sit at the 50 yard line in any weather.

My 2007 MKV 2.5 Jetta is still having overheat problems even after changing the tstat to a OEM (Wahler) and the waterpump to one with metal impeller, which works way better than the original.

My Wahler thermostat starts to leak after 4 years. It's not a big leak (only a cup a month) but I'd swap it asap.

Just not Motorad--unless you want to replace it again in 6 months

I got a bad mishimoto thermostat with similar results.
