Currently have no problems with my set up, just a bit worried, when summer rolls on by here in california, 105-115 degree dry weather. I already feel the turbo is adding a great amount of heat into the engine bay, and i just dont want anything to melt. I believe theyre tuned to turn on at a certain temp, and stay on.


I have the stock cooling system, turbo blanket, and down pipe wrap, anything else i can add? Bigger radiator or Bigger Fans?

Was looking at this, but wasnt too sure.

2-ROW ALUMINUM RACING RADIATOR+2 FAN 99-12 CHEVY SILVERADO 1500/2500 4.8/5.3L AT

Reason im concerned was because even when i was non FI, the temp still climbed a bit in the summer.

I had that aftermarket radiator and ran 70% DI/30% antifreeze. 160 degree thermostat.

I always kept my ECTs in the 170s when boosting and ran E85. Some would argue that is too cool, but I believe in keeping the motor chilly to keep it alive.

With that rad and above additions, truck would run 163-168F on the highway. In stop and go traffic in 100F ambient temps I could keep the truck wherever I would set the Efans at. And yes, underhood was a furnace. Lots of DEI cool tape and titanium wrap.

Thanks for the reply! Did you get it with the efans as well or just the radiator? If you got just the radiator did the stock fans mount just like stock too?

Got the Tstat ordered from ebay. Now i gotta look through radiators.

Didnt someone or you just post this exact question two weeks ago?

There are alot of ways to reduce and protect from heat.
There are many threads here going into deep detail on what to do and what to buy.


Once my tequilla kicks in i may edit this post and go into detail again.
But please dig alil deeper here and you will find everything you want to know.

I did find some threads, on ls1tech/PT/Vette forums, but every year is different, new products come out. Was wondering if someone had a unique/different set up. Not to mention, there is a lot of conflicting replies on some of the threads(like using a low temp tstat, most replies were based on non FI setups), and i usually take personal experience advice like GMCtrk who has the set up already, and whos thread i had seen giving the same advice, the reason i bought the tstat right after i read the reply.

Might use some DEI wrap on some of the coolant lines, from some of your old posts i read.

Thanks for the reply brotha

What's the temp issue.
Coolant getting hot?
Or the engine bay is hot?
Need a little more info.

TURBO'ing a truck will add more heat to the engine bay, but the stock cooling system should be fine. As long as it's working properly.

Was afraid this would happen. Today the weather was 98* with about 30% humidity.

Coolant started boiling, and the coolant tank got damaged, i just replaced it (Luckily it happened on my driveway). However, went for another spin, and was stepping on it, going wot here and there, and it started climbing past the 210.

I dont know what to do. I was thinking of getting a 160 thermostat, and doing a coolant flush. Water pump seems to be doing okay. Since the temp steps back down when im at a stop.

What coolant to water ratio are you using?

A good coolant ratio of like 60/40 to 70/30 (coolant/water) should raise the water boiling point to around 235-240 give or take. I could see a 50/50 or less causing it to boil much much faster.

Your previous post said you bought a colder thermostat, did you not install one?

I would install a 170-180 to drop your temps another 10-15 on average.

Thank you for your reply! Im going to do a coolant flush, with proper fluid measurements, and try a 160 thermostat.

I had ordered a 160 thermostat, but i was training on base, and post office returned it, and never got to install it.

Do you think my tune can be causing overheating issues? However, idk, I do not think its my tune, because even before my turbo install, my temp would still climb in 105 degree weather, i even got the engine hot on the cluster once, even before my turbo install.

Just very disappointed in my truck right now. I really dont want to sell it.

With a stock thermostat 210 isnt abnormal, what temp are your fans set to come on? Who tuned it?
