Default Turbo LS1 running hot

Hey all. Just looking for some ideas or insight. My car is a 2000 Camaro with a stock internal LS1 and a Huron Speed single turbo kit. Stock radiator, derale pusher fans and stock thermostat. Its been turbo for about a year now with no issues but out of nowhere the other day I noticed the car was running just a hair above normal (probably 190*-195* cruising on a cool day) and at idle it would get up to 240* best part is the factory gauge was just hanging out at 210 where it always is lol. It usually stays 180* despite the ambient temp at cruising and will see 220 idling or in traffic after a while but the fans always bring it back down. Car has no AC or condenser. Any insight would be appreciated. Not sure where I should start diagnosing.

Are you positive the fans are coming on when they should?

Verify the t-stat is operating like it should and the fan is coming on when it should. Radiator full? Is a head gasket blown? This is basic diagnosis.

Get the stock thermostat out of there and put a 160 in it. Make sure fans are coming on in the 180 range. Make sure front air dam is still installed. You should NEVER hit 240 with no AC/condenser installed. Is it tuned well?

I haven't gotten a chance to check anything yet but thank you for giving me some places to start.

I like having heat since I drive the car in the cold weather until it snows. I thought about putting a 180 in it and wish I had while it was apart and the system was dry, but I think a 160 would be too cold for me. It is tuned well, I never had a problem until the other day. Its been a year since it was tuned and I haven't changed anything.

Just because you put a 160 stat in it doesn't mean the car will run at 160. Most turbo cars we do run in the 180's-190's and have 160 stats. Shoot my LS6 has a 160 stat and runs around 170 and gets up to 190s with AC. Either way i would yank the stock stat and check the fan turn on/off.

I know it wont run at 160 but my brother in law has a 160 in his TA and the heat barely works in his car so I just figured I would stay stock but maybe ill do a 180

240 isn't overheated. Pretty sure high speed fans come on around 235. Mine will run 230 sitting still for a long time in 90 degree heat with the air on, and around 200-205 moving. Motor is on the stand now, and is in good shape, you're fine.

Second on the 160 stat and make sure your tune has the fans coming on at 160 or 180 or whatever.
I've heard of guys getting the fueling set but forgetting to lower the fan temp.
