Default Is your LSx overheating?? HERES WHY..[PICS]

These pictures are UNALTERED..

I pulled the waterpump to start a cam swap, and this is what I saw. God only knows whats inide the radiator, waterpump, and waterjackets..

What moron company would allow powdercoat to get inside the water ports???

NO, I am not having cooling issues. But just in case someone else is, it may be because the powdercoating has blocked up your system..

Machine shops: Do us shops and customers a favor and clean up the waterports PRIOR to building the motor..(even though you shouldnt have to.)

Well, on to calling GMPP....

Do you still have Dex Cool? That looks like the typical garbage caused from that wonderful invention.

If you still have it.....whether that is the cause, I strongly suggest switching to a "global" type coolant.

This motors got about 1100 miles on it...

What your seeing is NOT the coolant. That is the powdercoat peeling off INSIDE my motor..

I run around 75/25 distilled/dex.

In other builds I have run EVERY combination imaginable. Where we live, the coolant isnt as necessary. Its only needed for lubrication properties.

Those blocks are NOT powdercoated. Take a rag with acetone and rub it - it comes off. They're PAINTED!
