Buy a kit at auto parts comes with adaptors and instructions
You still need to flush the engine block and heater core.
remove thermostat housing and lower radiator hose from block flush through block.
Ive never heard of draining coolant plugs except on a diesel engine . Once you drain the coolant and flush the system it should be fine
Take it to dealer and hope they do it correctly, There is a plug on bottom of radiator loosen and it drains coolant out of radiator, but not out of engine, There are plugs on the side of the engine block that have to be removed to drain coolant out of block. Probably impossible to get to and accidents happen, sorry I hope this helps some.
Do you mean flush the oil (not recommended) or flush the coolant?
To flush an engine of coolant in the engine of a Kian Spectra refer to the manual. Auto manuals can be purchased at auto part retails or in bookstores.
If coolant is rusty or dirty - yes
Actually, the drain is a Allen or hex-key screw located on the right side of the block towards the back of the engine. In fact, is is roughly above the oil filter and is almost flush with the block. Look beneath the carburetor with a mirror or from beneath the vehicle and you'll see it. The block needs to be drained when performing a full flush.
DO NOT FLUSH the coolant system on a northstar. Drain the coolant, replace with 50/50 Dexcool and fresh clean water, and you're good to go. Especially NEVER NEVER buy a "Coolant Flush" at a dealer or quicky-lube place. All you'll get is the previous sucker's engine gunk pumped in to your engine.
Hi it'slikelyto be oxidisation particles from the aluminium either block or radiator mixed with coolant.A good engine flush and coolantreplacementwould be a good idea.
You can flush the block thru the line to the heater core at the firewall. This will flush the heater core also.
When you changed the Radiator did you flush the engine to remove the transmission fluid that the already mixed with your water in the engine block. If not that would explain the presence of the fluid in the coolant holding tank.
