Did LIM full job a few months back including new tep sensor in LIM
New Water pump
Rad looks brand new
New rad cap
Tried 2 thermostats now
Coolant flushed

About a week ago car was overheating fairly quickly once it go up to temp, no idea why so I pulled the t-stat right out and voila no overheating in fact car barely registered on needle during long drives & idling. I figured a bad t-stat.... got another 195 degree stocker again today and boom car overheating!

Upper rad hose feels hot but not tons of pressure. If I crack the bleeder at idle RPM coolant will stream out then stop (this is when the car is already at 212 deg). To help facilitate the air bleed I rev up the engine to 2K and hold. I expect coolant to come flying out as it passes the t-stat but I get absolutely nothing. However, when t-stat gone coolant flows out like a champ.

Need help here folks!
