Drove my beast with the new t-stat and it is much more alive. I did have a lot of other things done, but I know there was the largest difference from my t-stat. It used to run 75-78 degrees Celsius, and now is around 81-84 degrees Celsius. That is a pretty large difference. I also had the temp sensor done as well.
I posted some pics below. As you can see, my old t-stat has 79 degrees Celsius on the top. Is that standard?
Been meaning to do this.
I have to do a flush as well.
Hoping to have to do the replacement ONE TIME. Unlike some of the people who kept getting o-ring tears and had to do the job multiple times.
Even with my cooler running - there is no appreciable change in Fuel Economy, or signs of running rich. Exhaust tips stay pretty much SOOT free.
Running my winter tires - Michelin Pilot Alpin PA3's 245's on 18x8.5" all around - I have no difficulty breaking traction even in the higher gears.
In order to eliminate any tearing, it helps to lubricate your oring before penetration...
I was about 5 minutes short of asking for a picture of a proper thermostat, as this one is a-typical in operation. Just about swap mine out after work as I am running at the first dot on the temp guage.
I have the parts in garage to do this too. What I find amazing is the price difference for the T stat. Some go from 46 dollar to 140 something from the dealer. I bought one spec'ed out for M5 but not a OEM, Behr - if I remember right. Rated at 79 degrees. Any one else find it prices all over the place too?
Glad to hear it makes a difference because mine was reading similar numbers.
I don't know about the prices....just bought it from Tischer.
I recently read about a member that was going to replace the tstat....but started with the sensors....ended up being a sensor & not the tstat. I ordered new sensors & tstat....will start with the sensors...change one....run it for a day....go to the next sensor if needed....run it for a day.....tstat last (hopefully save some possibly un-needed work)
Well id start with the sensor, its cheap and easy to replace (20 min). If that doesnt help, then go for the thermostat. If i can give one piece of advice for anyone doing DIY work its, take your time and work at a pace comfortable for you. Do it right once and you wont have to do it again, because nothings worse then re-doing a job you've already done.
Take pictures, make notes, individually bag bolts/parts, do what you need to do so you dont forget where stuff goes.
