How to remove coolant before remove intake?

[nelson84]

I have an 84 vette and will be porting the intake. What is the best way to remove the coolant from the intake so it doesn't spill all over everything? Is there a way of draining most of it?

I wanna know this too. Let's see which expert will know the answer.

On my 1982 (same L83 motor) I just opened the valve on the radiator.

Water flows to the lowest point, and the valve on the bottom of the radiator is lower than the intake manifold.

After you do that, there could still be some fluid trapped in the upper radiator hose.

Good Luck!

Anybody have an environmentally friendly way to collect the stuff. While I'm not a tree hugger in the strictest sense, this is some nasty stuff that should not be allowed to drain into the storm sewer and into the water system untreated.

Total coolant drain

Remove the knock sensors as well as opening the radiator drain. Sounds like a lot of work but it's worth it. Remove the fill cap to speed draining. You may have to poke the hole after removing the knock sensors as they really get scaled over. There will be a flood when the knock sensors come out or the scale breaks loose so have your drain pans ready.
I use one of my grand-kids small plastic sand box cover to catch splash from the regular drain pan. The drain pan sits inside the plastic 'bowl' (it's about 4' diameter and 5" deep. Don't miss a drop.

Now if only I had room in the garage to store this machine that I will use once every two years.

I have a inline electric TPI fuel pump with 3 feet of hose on each end. Then just use aligator clips to power it from the battery. Drain the coolant into a 5 gallon dirt bike gas can never a drop lost. Then if need be I have a valve fitting on the block I can connect this pump to if I need to drain the block.

Nice clean and easy way to recover coolant and have no mess whatsoever!

The drain valve is on the radiator under the radiator hose , pass side.
Easiest to access valve from wheel well under frame or under car than down from from the top.
There is minimal coolant left in the top hose after that has finished draining.

I use one of those hand-operated vacuum pumps (that you can get from any parts store). Remove the heater hose from the rear of the intake and stick the plastic tube into the intake through there. You can blow into the plastic tube to tell when you've hit coolant. Hook the vacuum pump with the little plastic "bottle" it comes with and use that to start siphoning coolant from the intake...as soon as it starts filling the little plastic bottle pull the tube from the intake off of the plastic bottle and just let it flow into an empty 5gal bucket. Works well for emptying the radiator too!
