Not replacing thermostat

I had read many members have chosen to replace their stock thermostat with one from Jet. I myself didn't question, I simply thought.. well, others are doing it and this is a cheap piece so I am sure there is good reason.

I ordered mine, and was looking towards installing it. What I didn't do, was google the pros/cons of doing it from knowledgable sources, or more importantly, talk to a mechanic with years upon years of Hemi experience.

I probably should have, I'd have said myself $60.

After talking with two different mechanics, I'm not going to replace my stock thermostat with the after market model that helps the Jeep to run a little cooler. Why you ask? Well, the most obvious reason - the entire 392 Hemi engine was designed to run at a certain temperature. When you change that equation, you alter how hard the internals are working and this can lead to engine damage and decreased fuel economy. (not that fuel econ is our biggest issue as SRT owners)

I know this will bother some users here, and that's not my intent in the least. My intent is to save some possible headaches. If you google it, talk to mechanics - both will tell you not to replace it. Yes, you'll find forum users in various places saying it's fine but are these guys mechanics? No.

I spoke to the master mechanic at the dealership and he laughed at the idea of replacing it. I spoke to a different mechanic at a place that does after market upgrades and he said the only time you do this is if you're building a track car. You will not see performance gains, you'll see more engine wear but at the track, it'll be cooler which of course at the track, matters.

Not sure this will help anyone, but hey - if one of you still want to buy the aftermarket Jet thermostat, i have one, unopened, yours for $40. Cheaper than anywhere else.



Not trying to sound like some anal retentive asshat saying to keep our rides stock.. ha.. I know some of the mods we do could alter different things. I just thought.. is a $60 mod really worth the risk? After talking to a different mechanics and googling it, for me anyway, it's not.

Then u shouldn't replace your springs because it will cause premature shock wear. ..guaranteed. You also shouldn't add a cai or higher flowing filter or intake because more dirt will get into your engine. I could go on and on....lol.

Re: Not replacing thermostat

I expected some people that previously had installed the tstat to come in and voice a differing opinion, and that's fine. Your ride, of course you're going to do what you want to do. I did post that I recognize we modify things and we get differing results at the bottom of my post by the way, so you're not saying anything I didn't already agree with.

I'm not trying to piss in anyone's corn flakes here. I'm just reporting back some info I learned by simply asking people that have gone to school and are trained with our engines. How someone uses or ignores the info, that's up to them. If you're going to raise a point of why the tstat rocks though, do so. For all I know you're a master mechanic and you know your stuff. By all means man, drop knowledge on me. If the after market tstat is awesome, I'd love to know why.

Anyone with training I have asked looks at me like I'm drunk.

I'm told it doesn't improve anything. If you're tracking your SRT daily, and that's it's use - then yes, it helps you because engine heat is an issue when racing/tracking a vehicle. If you're not tracking, it doesn't help you.

Re: Not replacing thermostat

From my understanding this is a worthless mod unless you have a tune. WIth a tune you should be find.
