Ok so I did the tstat bypass along with a new airtech WP and a HD fan clutch. I was seeing temps spiking up to 220 to 222 at idle and speeds over 70 mph.Crusing at 45 to 65 I was seeing 208 to 212. Now after the work was done Im seeing 183 to 184 at idle and 184 at 80 mph, Crusing at 45 to 65 is 168 to 177. Dont I need to at least get into the 190 range to be at full operating temp? Are my numbers too good now ? Should I step up to a 190 tstat? Wait till summer and see what happens as air temp rises? No doubt this mod stuffed the high temps , 03 Disco 2

 

 

I would say your old temps are an indication of air but no one seems to appreciate knowing that...just more money, parts and time to waste.

 

The old set up was the stock tstat setup. I did the "inline* tstat setup with the 180 tstat, Sorry I totally blew that first description. Im in Georgia . I did a 30 mile dive that included stop and go and freeway.

 

Nope....no air...I used a vacuum pump to fill the system. I think my issue was a bad WP but I wanted to the inline at the same time so I went ahead with it. The pump was obviously dragging at times.

 

Those are normal temps for the bypass stat mod. You are fully warmed up, but it will throw low temperature codes if you run a stat below 180. Enjoy!

 

Looks great. I throw a PO126 "too long to reach temperature" code every time I start my 03 D2 up, but my ambient temps have remained cool here in Missouri. Your running temps coincide with mine. If you aren't seeing that code, that is encouraging to me as spring has begun to sprang here now and maybe it will quit doing that as soon as the delta is smaller. You did a nice job on that!

 

 

I havnt checked yet . My SES light is on due to SAI delete at the moment so I dont know/ Ill read the codes again soon.
