My engine is in a 98 sls, 4.6 N*. Are you familiar with the product called K&W amp nanotechology head gasket and block sealer. Does it work.

 

Can you explain to me how you drain the coolant on a 98 sls. theres no drain valve. Do you pull the small hose on bottom of radiator on passenger side of car.

 

Not sure about a 98 radiator but on my 95 the drain plug is on the driver side at bottom. It isnt like the brass **** valves that extend out on older cars I have had. It's just a plastic screw in plug that can be over looked if you dont look close enough. If you cant find it just pull the lower radiator hose off slowly. Does the same thing just a little messier. And obviously dont do it when the engine is hot or you will get burnt bad. Also Pets like to drink antifreeze and it only takes about a teaspoon to kill a dog so dont just drain on ground!!!
