How often should you add antifreeze

There are different opinions about the frequency of Antifreeze changes. Some people go by time, others also use mileage as indicators. First, use a compatible fluid, as there are several.

I would say every 3 years. If your engine has a lot of aluminum it should be changed more frequently. Really people overlook the Radiator material as it is usually Aluminum and it needs love too.

Sometimes the job can be messy, some Makers do not supply a drain fitting and expect you to just pull the bottom Radiator hose loose. I would also suggest no more than 40,000 miles between changes, probably 36,000 is recommended in most.

1999 olds silhouette heat is warm when running but the gets cooler when idling also heater hoses have no pressure on them. I have checked coolant level added some. Checked for air in cooling system by...

The heater core could be clogged. If your antifreeze is orange , then it is Dexcool antifreeze which causes slime and sludge to build up in the cooling system. It can clog a heater core. My suggestion would be to drain and flush the entire cooling system with Prestone Super Flush. Put in a new thermostat while your at it. Refill the cooling system with a green antifreeze that is labeled compatible with aluminum engine parts and radiators.Do Not refill with Dexcool antifreeze.

What type of antifreeze is used in shadow vt500

Standard auto antifreeze. Follow directions on the back and make sure you dilute the antifreeze with water. Undiluted doesn't provide enough protection.

Water leaking from head

Are you using a Phosphate free antifreeze. This should NOT happen if you are. Phosphates in regular antifreeze eat and pit the aluminum that the heads are made of. Have you ever seen an old piece of aluminum that's all powdery and pitted and nasty ? phosphates in regular antifreeze do it even worse. sounds like you will have to replace the leaking heads. Then make sure you never use regular antifreeze in your bus. Dexcool is a good one to use but there are lots of other brands now that so many autos have aluminum heads. also if your going to replace heads I would get performance heads. little bit more money but way WAY worth it. More power is much needed in any bus. :)
