I am planning to try this this weekend. You mentioned something about the key way for the fan bracket. How do you remove it safely. Also, did you drain the coolant before removing the hose and thermostat housing?
Is there a need to replace the thermostat housing that connects to the block? Someone told me that the factory ones have a poor flowrate.. Truck is throwing this code, and has 200k miles on it. Any suggestion there??
Do you just drop the new thermostats in? No clock wise turning them? I just dropped mine in and losing coolant not sure if thermostats are not sealed inside or If I didn’t tighten the bolts correctly
Note: The fuel pick up in the tank is mounted permanently at the bottom of the tank so it does not matter what the fuel level is! Fuel is always picked up from the bottom of the tank.
Anyone know why my coolant is getting pushed into the reservoir side. No codes ,engine is running normal temps and i literally just replaced both thermostats and tank.
Do NOT buy those thermostats. OEM only. IF you buy aftermarket, it had better look nearly identical in construction to OE. These Israeli tstats are obviously cheap/not suited for duty in these trucks. It may not be day one, but you WILL have problems down the road for using them.
FYI, 1 T-stat is 185 degree (front) the rear is 180 degree from GM. I only stick w/ GM OEM parts. Good video.

Did you drain any coolant before you started I didn’t notice
Thanks for the video
Thank you very much for this video sir. I appreciate you.
I second that
That is the fuel system test port that you referred to as a refrigerant port. Also the duramax was co developed with Isuzu.
Thank you
Thanks for mentioning the thermostat gaskets are the only gaskets for the housing
You bet

I am not familiar with a code for that. What code do you get?
Did you have to purge your coolant system afterwards?
is that refrigerant line or fuel rail test port you removed the bracket bolts from?
Good question 😅
It’s fuel rail test port
How those o reilys thermostat holding up?
So far so good. I live in coastal california so the weather is not severe.

I'm not sure what you mean by clock wise turning, I did drop them in and clocked them according to specs. How much coolant are you losing?
Good info
i’m getting same code but my truck runs at normal temp what’s the issue?
Good question
Maybe a sensor or electrical. Electrical are always bad on these trucks
same problem . your thermostats are stuck open . mine was the same
@@dp9629 come down to it. You are right. That's what mine was.
@@floridagirl386 I swapped the ect sensor on the hopes it was going to be that easy but shot the code again about a week later.
Very interesting , thanks. I never run below 1/4 tank on fuel, due to dirt getting sucked up out of the bottom of the tank. 👍

Great video sr!!!👍
Glad you liked it!
Did you need to burp it?
Yes
I also got the Israel thermostats from Napa, they said they were 180-185, but currently running steady at 203, how about yours
Thanks
I’m thinking! The thermostat with the wholes goes to the back of engine. Not the front
Yup, probably

Any luck? Mines doing the same thing
Head gasket
No, not head gasket, no coolant in oil and has no signs of that issue. Was told it may be turbo going out or something in that area
You like to hear yourself talk.
