i'm trying to replace my upper and lower radiator hoses. do have drain out the coolant to do so? how much coolant does the S need (#quarts)? and is there any instructions on the site on removing it?

 

If your coolant is still good use a clean pan to save it, open the drain valve on the radiator, drain it, change hoses, fill it again. Be very careful with the coolant as it is very poisonous, wash your hands well after handling it and make sure you don't touch your mouth with coolant on your hands!

 

Since you have a 2000MY vehicle, you should flush your system if you haven't done it already. If it's already been flushed and replaced in the past, you can reuse it. Open the cock valve on the bottom of the radiator and drain it before removing the hoses.

Ethylene glycol (antifreeze) is poisonous if ingested, but I wouldn't call it very poisonous. You don't want to drink it but if you happen to touch your lips on your fingers that have some on there, you'll notice a very sweet taste. Incidental contact like that won't hurt you. Older cars with copper radiators had lead solder, which was much worse.

If you only drain your radiator, a gallon of premixed coolant should be enough. If you plan on flushing the entire system, you better have 2 gallons handy. The use of Honda radiator fluid is preferred, since it is a silicate-free coolant that won't harm your aluminum block or gaskets. Standard Prestone anti-freeze is a no-no.

 

Still worth being careful MSDS Ethylene Glycol. Particularly toxic to pets (cats/dogs?). Don't let your pets near any spilt fluid.

 

Thanks so much guys.

 

one more question, how do i flush my whole system? beside the valve opening on the radiator is there another place to open to flush the system?
