The feature set and design is very attractive. It uses a Meziere 50 or 55 gal (forgot which) per minute electric water pump and a 5000 cfm MK VIII fan. When you start the car both the water pump and the fan get a soft start so you don't overload your electrical system. There is no thermostat! In the top radiator hose there is a temperature sensor that measures the temperature of the coolant leaving the engine. You set your target temperature and the system provides a closed loop control of engine temperature by seamlessly raising and lowering both the pump and fan speeds to maintain the target temperature you have selected. At highway speed the fan shuts down.
When you park the car the unit will continue to run both the fan and the water pump for a minute to a minute and a half slowly but uniformly cooling the engine down. It is a very nice package both in terms of cooling capacity and also in terms of nice touches like the short run on period after you shut off the engine.
Ask for Dave at Hollister Road Co. He is super easy to communicate with and helpful beyond your expectations. The phone number is 713-937-0387.
Almost forgot, when you remove the thermostat and the obstruction it represented in terms of coolant flow it is stunning how much more heat energy your cooling system can sink away.

p.s. The 85A fan only controller is listed as out of stock but I believe the 125A is still available. Dave should be able to give you an availability on the fan only controller if that is the route you choose to go. |
Great post, good info Ed, thanks
Where in the world did you mount that thing?
I have had no problem with my fan and I am staying with a traditional water pump. My fan also stays on for a good 3-5 minutes after I shut the car off. My the fan is on a relay and I thought that solved the problem of starting up big load?
Is the fan only much cheaper
I will probably keep it simple and not do this mod ....for the moment anyway!
I think I will call him per your suggestion and get his input
