Very important..... I guess I figured they woudl read the directions!!!!

That condition would be called hydrolock, and that isnt good.....

After you let it sit, run the sh*t out of it clear out all that stuff!!! Its an excuse to go fast.... Do at least 3 or 4 redlines.....

If you get pulled over, just say "officer, I was cleaning out my engine"

The brake booster is a black, thick frisbe looking thing on the drivers side mounted to the firewall...... There should then be a hose connected to it, that leads to the intake...... When you unplug this hose, you will hear a hissing noise, which is normal......

When you apply the liquid you will put it in that hose, and when your done just plug the hose back in.....

Okay can someone give me a name brand and what it may say? Aree these top engine cleaners meant to into the gas tank but instead we're putting it in through the brake booster?

I went to kragen and I found some bottles for like 3 to 6 bucks that say will clean the valves and carbon deposits from the pistons, but IM confused because they say to put it in through the gas tank?

I need brand name.

There is a connection between antifreeze and NOx levels, but it's different than what you wrote.

LOW coolant = engine running hot = increased combustion chamber temperature = increased combustion chamber pressure = ripe conditions for formation of NOx.

I haven't used any of these "top engine cleaner" products for a long time. Some names to look for are Gum-out, CD2, Gunk, STP, etc. Read the labels in the parts store. Typically they are labelled to remove varnish, carbon deposits on valves, free up stuck rings, etc. Packaging may have changed, but these always used to be in metal cans with a pull-top lid (like a pudding cup) because the solvents in them will dissolve plastics (don't spill any on your paint or your driveway).

I can relate to what Wes is saying about the white smoke. Once while a student I used an aerosol can of carb cleaner on my 84 Charger (Omni). I was in the parking lot at work at lunch merrily spraying this stuff down the carb throat & revving the snot out of the engine. I finished the can, stood up & looked over the top of the hood to see a wall of white smoke 50ft high and 200 feet long drifting across the parking lot. Oops.

Good luck. Emissions compliance can be a pain in the arse.

Go to the GM dealer and ask for a can of "Top Engine Cleaner". I don't have the part number with me but I can get it. Directions are on the can.
The other products that you mentioned are shotgun type products that are actually fuel additives.

The fuel additves really dont do much...... The only one that actually does anything is BG44k, and you can only get that at BG product dealers......

The reason you put it through the brake booster is because it gets it directly into the intake, rather than going through the fuel system...... It can also clean up the intake tract to a certain degree.......

You could also use SEAFOAM....... Its about the same stuff, but the TOP ENGINE CLEANER is made for the intake system.......
