Hi All - A couple of weeks ago the check engine light came up, while I was on the highway.. Quick glance to the engine temp, showed it had not reached its optimal temperature. Reached back home and took a look in the diagnostics, I was able to get the P0128 - Thermostat Rationality error code. Looked up online and the results stated showed it might be a faulty thermostat or any leak in the coolant line.. I went ahead and cleared the DTC's and for a couple of weeks I let the engine heat up before I take off and I've observed it takes at-least ~10-15 mins on idle for the temp to reach at mid level. Again the light popped back up last night and I want to get this rectified.
I'm strongly planning on changing the thermostat, because I'vent found any leaks in coolant and a search on how to do it brings me to WAYLIFE thread, which make me more happier than ever. Thanks to @scull20 for this write up, so before I land up with this job, is there anything else that I should be looking at to rule out other possible causes?
also how soon should i get this fixed, I mean now I really wait till the engine temp gets to mid to start my drive, so I'm assuming at least this work around will not have an adverse affect on the engine right?
