I know, just looks dinky. |

Peter,
Those thin belts are racing belts and are designed to withstand high RPM's compared to normal V-belts. |

Ben,
There is only one way that one could "blow out 3 water pumps" as your source indicated. That would be by running the water pumps dry, that is, there was an air pocket in the impeller chamber that prevented the pump from being primed. He ran long enough to heat up the seal and cause it to leak.
Viscosity of the fluid being pumped is a factor in flow velocity but not a factor in pump life.
NPG+ is reduced in viscosity from NPG so it is easier to use than NPG. In nearly all cases no modifications need be made to existing hardware to convert from a water-based system.
Why make any effort to change the cooling system? Because cooling system failure is inconvenient and because it is so easy to tap into a cooling system's reserve capacity just by using NPG+.
After all, you've already bought the Ferrari. Wouldn't you like to run the air conditioner on a hot day when you're in traffic? |

I don't think there's any concern with the pump, but I can't get over how miniscule the Gates belts are on these things! This is the kind of rubber belt you'd find in a Lego kit! |

The 3x8s do have a much more accesible waterpump. Ferraris in general have very powerful/durable waterpumps. There is almost no resitance on them (most cars run other things off of the waterpump belt) so there is very little strain on the axle. It should be better than many other cars at taking any added strain from this stuff if there is any, but if it goes it's a little bit of a pain cause it's a Ferrari part. But the waterpump doesn't have very much to it, so as far as Ferrari parts go, it is just about the easiest to fix. |

ok I may have been mistaken I didn't spefically ask about NPG+ vs. NPG so it may have been the older stuff that was problematic (for that guy). I was just asking around in general about it vs. regular cooling.
Thanks for the clarification Paul.

Heath & Ben,
1st: I live in Florida and the past week temps have been in the mid 90's.
2nd: NPG + is a new product that is thinner than NPG, The Ferrari unlike most other cars does not need any cooling systems mods since it runs a full flow system. I do advice you to run a good syn oil so that you have complete hi temp protection.

I asked around about this seems one local Audi repair place is in love with NPG+ as well. Well I kept asking around and well one guy blew out 3 water pumps (in just a few months) becuase the stuff is a bit thicker than just plain ol' H2O. After his 3rd pump replacement he want back to standard coolant mix and never again had any problems. While I'm interested in hearing more about your experiences, my TR's water pump is far too valuable an item (labor wise = engine drop) to take ANY risk of this nature, IMHO. Somehow I think (I have no experience whatsoever with, so correct me if I'm wrong) the 3x8's have an easier water pump to remove if anything like that were to happen.
Just my thoughts.

WHAT PART OF THE COUNTRY DO YOU LIVE IN? DOWN HERE IN THE SOUTH IT GETS REAL WARM. PLEASE KEEP POSTING UPDATES. I'M REAL INTERESTED IN YOUR LONG TERM RESULTS.

I have now been running Evans Cooling NPG+ a waterless cooling fluid for a week now and I am never going back to water again.
At 220 degrees I can open expansion tank cap without a problem and my boiling point is 370 degrees and freeze point is -70 where it will contract not expand. The stuff is non lethal to people and animals and is good for 100,000 miles.
No more pressurized cooling system problems like blown hoses and gaskets.
