not that im aware. first dont start the car. get a small can or bucket to catch what is left in the hose. take and loosen the clamp at the stat first. pull the hose and hold it in the air higher then the top of the radiator. although there should only be drips of coolant in there ya never know.put the new hose on the stat part. get ready for there might be some spillage here. take loosen the radiator part of the hose ..pull it and get the other end slipped on in a hurry if you do encounter some leakage. its all pretty much a straight forward deal. pretty much one of those "fun" easy projects to do. no need to drain the system unless the coolant isnt protecting anymore or is contaminated. good luck!

...then, after you drive it for the first few times, keep your eye on the coolant level. It usually goes down as the air bubbles are flushed out of the block, and you need to add coolant.

cool..... thanks guys...... i was kinda sad that that happened today since it was a nice day and i wanted to drive my vette.
but its ok it looks like that needed to be flush and put new coolant anyways. it looked dirty when it spilled a little bit from the leak so its something that it need to be done.

If you drain your system you will need to burp the air out. I find the easiest way to do that is to park the car on an incline so the rad fill is the highest point. Then with the rad cap off let the car idle at temp for a few minutes.

Yep, raise the front end to burp with the radiator cap off.
Replace the radiator cap when the thermostat opens and the water starts to flow. Clean up/empty old coolant - pets lap it up then die.

When you refill your radiator with antifreeze pull the heater hose off of your intake manifold and fill until water comes out of the manifold connection. That way you are assured that all the air is out of your water pump and engine.

You can eliminate the need to bleed radiators by using a thermostat that has bypass holes. EMP/Stewart (sold by Summitt) works very well. Should the thermostat every fail, the bypass holes allow water/fluid flow. You can also drill your own holes, 2 each 3/16" in your current thermostat. These also work great for allowing air to pass through the system while refilling fluid.
