Scotty, I am looking to do a coolant flush on my 2000 Pontiac Bonneville and I'll probably do it on my 2010 Toyota Sequoia as well. Can you give me some tips?? I'm probably gonna have to replace the inlet and outlet hoses on the Bonneville because I know I'm going to have to cut them off. As far as flushing the heater core, is there anything I need to look out for?? I can use a garden hose to flush the system and heater core right??
After 20+ years, it's time for new hoses anyway (a new serpentine belt would be a good idea, too).
Get one of these kits, so it's easy to do a flush this time and next time - the price is right. Prestone radiator flush and cleaner works great, too.

I wouldn't cut any hoses. They are molded to fit your engine. All you need to do is yank one end off the water pump.
Usually the hoses are 3/4" and 5/8" diameter. You can buy extra pieces of vinyl tubing at the hardware store for only cents per foot. Then buy one of those 'T' adapters that glen has shown.
Here's what I did:
I already bought both inlet and outlet hoses that go to and from the heatercore. They are molded. The hoses on the vehicle now are pretty much seized and instead of breaking something, I thought it would be best to just cut the hose off so nothing gets damaged. There's no issue as far as flushing the heater core with a garden hose right???
that's how I do it
