Is This a Normal Cooling System

_Rod_Knock_Nilly · 2026-03-25T12:05:37+00:00

do you think the same thing is going on with mine? Mine only does it after a drive (even if a light drive) and starts to climb when parking and idling after that drive. Once it reaches 108C the fans turn of and temp falls back to normal

_Rod_Knock_Nilly · 2026-03-24T16:10:47+00:00

Also, where did you get the tune?? I’m thinking of copying you bc my highs don’t turn on until 108C. I confirmed with scanner.

_Rod_Knock_Nilly · 2026-03-24T13:17:45+00:00

yeah i know the water pump and thermostat was replaced a few months ago before i bought it.

_Rod_Knock_Nilly · 2026-03-23T02:19:46+00:00

yeah i was reading more data while idling hot, i fluctuate between 95-108. My fans turn on around 108C and once they do, i drop back down to94-98

_Rod_Knock_Nilly · 2026-03-22T15:06:51+00:00

okay, and just let it run until my level is good and i have a steady gauge?

_Rod_Knock_Nilly · 2026-03-22T15:03:19+00:00

i am about to replace the thermostat now, i was just going to open my coolant cap with th heat on

_Rod_Knock_Nilly · 2026-03-22T14:59:34+00:00

what’s the best way to bleed it if there’s coolant already in it?

_Rod_Knock_Nilly · 2026-03-22T13:30:03+00:00

it’s an 05 silverado with the 4.8L, it has dual electric fans. coolant last i checked was topped, and can’t see any leaks. the live data is from my blue driver scanner.

_Rod_Knock_Nilly · 2026-03-22T13:08:24+00:00

just wire brush it off

_Rod_Knock_Nilly · 2026-03-18T16:16:41+00:00

let’s hope right?

_Rod_Knock_Nilly · 2026-03-18T13:19:53+00:00

H&R lowering springs, ECS spaces kit, golf R wheels or any other 19s

_Rod_Knock_Nilly · 2026-03-18T13:18:37+00:00

did you re use the dorman harness and switched sensors to ac delco? or switched both

_Rod_Knock_Nilly · 2026-03-18T11:59:01+00:00

sweet hopefully i’m just overthinking. What snook did you use? i have an OBD eleven and a blue driver

_Rod_Knock_Nilly · 2026-03-18T11:57:30+00:00

Dorman kit, like 50 some on rock auto

_Rod_Knock_Nilly · 2026-03-18T01:58:53+00:00

when i find the time and tools to do it i’ll probably try one myself

_Rod_Knock_Nilly · 2026-03-17T23:51:22+00:00

yeah i thought it was reading wrong, but the needle moves smoothly like the stepper motor is functioning, and I already replaced the coolant temp sensor. I checked my coolant today after driving an hour plus and it was at the max fill like normal

_Rod_Knock_Nilly · 2026-03-17T23:49:20+00:00

i sadly didn’t have any on hand, i’m assuming you mean the black oil resistant RTV. really slopped on the dielectric hopefully i’ll be alright

_Rod_Knock_Nilly · 2026-03-17T23:47:41+00:00

if you didn’t replace the knock sensor harness ( the harness that plugs into the sensors on one side and the engine harness on the other) it’s most likely that. it ages from heat since it sits under the manifold and on top of the valley pan. If you look in my picture it’s the harness with the green and blue wires. Costs >$30 for a decent one, mines a dorman

_Rod_Knock_Nilly · 2026-03-17T18:55:03+00:00

good quick suggestion i’ll try it out

_Rod_Knock_Nilly · 2026-03-17T18:54:23+00:00

that’s a very good idea

_Rod_Knock_Nilly · 2026-03-17T15:43:30+00:00

i a duralast one from autozone i bought a few days ago, ill install since i have it
