Well an update to everyone i did a full flush man that coolant was disgusting somee brrown crap no oil in it tho seems like the previoos ownewr put stuff in it maybe sealer? welll there is NO SMOKE!! i havent done the block test yet ( i will doo it tomarrow) But when i first saw the smooke it was a **** ton just drove it foorr a hour engine didn ooverr heat oil levels are good and coolant isnt going down. Ill run a few more tests but it looks promiising right now. Oil looks a lil brown but their is no foam on the dip stick. Ill do a oil change aswell just incase. Will give an update tomarrow.

 

It doesn't take much coolant leaking into the engine to make smoke. If it's smoking still - something is wrong.

 

When I start my engine up their is a little smoke (I am in Ann Arbor Michigan and its very humid) So their is somee white smoke but nothing even closee to the scale I have seen on youtube from people who have actualy had coolant fails.

 

The brown sludge in your coolant was probably Redline Water Wetter. It reacts with some coolant additives and polymerizes into brown or black crud over time. It is an old technology additive that shouldn't be used with anything but pure distilled water at this point. Royal Purple and Mocal make better, more modern products, but none of those additives are actually needed, unless you are running straight water. They may add a tiny amount of cooling capacity to the system, but their main purpose is to lubricate the water pump, in the absence of glycol.

As for that K-Seal recommendation, it should be used only as a very last resort, and you should not get your hopes up. No way I would put that stuff in my engine.

 

i have coolant coming out spark plugs after a radiator change. any answers?

 

Fucked.... I won't be to much help but I was also given no info accept for coolant in the engine which should never happen under any circumstance unless something is greatly messed up. Maybe give some more info maybe like why you changed the radiator, was there any problems to began with, How did you find out there was coolant in the engine. Just something like that would help greatly in us helping you
