Coolant for Rebuilt motor

[gabedrummin]

Dose anyone know what Coolant /Antifreeze is recommended for a LN Enginnering motor ?

[dghii]

The IMS bearing has nothing to do with the cooling system of the car. Use the recommended antifreeze....Porsche coolant, Zerex extended life, etc. Not going to recommend any specific coolant but I stuck to the Porsche coolant so I didn't have to think too hard.

If you think there might be some magic elixir coolant for an 'LN engineering motor' why don't you ask LN Engineering? Surely they would know.

Haha! They probably sell some proprietary blend I’m sure...

Go with Porsche fluid. Just makes it easy. Keep in mind one gallon is actually 2 with 50/50 solution.

You need an OAT coolant. If you can find a generic one for modern Japanese or Euro cars, you can use it. I use Prestone Dexxcool, and get it at Walmart, full strength. Then go over to the grocery dept. and buy .88 gallons of distilled water. It's orange, btw. I don't ever buy premix. Sucker product, paying a bunch of $$ for distilled water.

Burner has a nice Youtube video about what coolant to use. Burner's videos are very worthwhile to watch & learn.

Toyota's is red btw.

You can get away with any brand if it's OAT, but don't mix in the green stuff.

I use Pentosin, it's pink and it's what the VW Dealership's use, and the label list Porsche also. It's in my VW Jetta and my Porsche. You can buy it at Advanced Auto for much less money. Be sure as other's say top off with Distilled Water. You are looking at 5 gallons I believe of coolant in the Boxster.
