Got the car
back to Perth from Melbourne just under 4000 k
Then rebuilt the engine
Not a bad product
*Not very expensive.
Cons: *Didn't work for me.
*Takes a long time to flush the system out completely.
I followed the directions on the bottle to the letter. I ended up flushing the cooling system 8 times before and 8 times after to make sure everything was completely clear. The product worked for 3 days, then I could feel when the plug gave way. The car loses power and idles rough. It's a leak between one of my cylinders and the cooling jacket through the head gasket, so it's pressurizing my cooling system and pushing the antifreeze out of the reservoir. This product says it works for head gaskets, but many will tell you that it doesn't work that often for that type of leak.
Looks like it's time to rip the head off and do it the most reliable way.
I tried some expensive stuff called Steel Seal that was mixed in the radiator fluid and claimed to work. Though it did partially work - the car would tripple its range to 15 miles it was still a junker. 8$ worth of KW has the car running properly every day for 9 months - though my trust level is low.
I can recommend the use of this product - just make sure you flush the system as any anti freeze left will bond and clog your system.
After long use the K&W sealer does not do the job fully, and I need a new shot. 8$ and 1 hour work per year is not bad though.
Still recommend it fully.
