This is true. They have some nice parts. Quality is there too!

My oem is going on 16 years

[camatv]

i prefer oem also.  oem gear and impeller etc..   never had any issues with them.  

 

i have a few low hour billet PD ones if anyone is looking..

I contacted mull and they are about 4 weeks out on impellers so i probably wait if not im going to do chariot but i do need to figure out which antifreeze to run because i am going to get a oversized radiator and its alumiumn

[DBR06Banshee10]

50/50 or straight?

[hoppedupandcutdown]

I prefer 50/50, that way you don't have to worry if your water has crap in it.

[DBR06Banshee10]

What if i use distilled water?

[hoppedupandcutdown]

that would be proper.

[DBR06Banshee10]

Ok will do

I run about 70/30. What zilla said about antifreeze is true.

 

Im not convinced overheating is due to any sort of design flaw. Plugged radiator or one thats beat to shit comes to mind as more likely along with jetting.

Or even a dirty rad. I took mine off once and flushed the outside with A/C coil cleaner and water and couldn't believe what came out.

[DBR06Banshee10]

Im still going to get the over sized rad cant go wrong with that

[DBR06Banshee10]

What kind of rad u brought? And what kind of impeller?

[Zillaguy]

You should always run an antifreeze and water mix... If you're going to run straight water, it needs some kind of lubricant in it, like Water Wetter or some other kind of additive... Other wise it could damage seals.. Water is a great coolant, but a terrible lubricant...
