From what I heard, the 2.x's have a dual fan in the PEM and the 1.5's only one. I believe jbadger mentioned his PEM temps did drop after this upgrade. Although it appears the real reason that a dual blower was added was for cold weather climates with salty roads and snow and failures occurring with the single fan.
I believe that is under the front hood, not in the rear correct? Is there an upgrade in the rear by the motor and PEM?
So the rear fans were not an upgrade for the 1.5?
dhrivnak, how hard is it to take the PEM off on the 1.5?
Thanks much.
Quick correction, I have a 2.0. Yes, my blower failed and so I took it in for service and got the dual blower assembly. It was a $1500 upgrade through the service department at Fremont.jbadger had his 1.5 retrofitted, he'd be a good person to ask questions about. I think this is a good move since keeping temps down on electronics typically lead to longevity of the components.
To my knowledge, my Roadster was never in cold climate (Sunny California), but yes i've heard they are prone to failure. The service department strongly recommended that I upgrade to the dual blower. I believe in previous threads I mistakenly called it a dual fan assembly, as I wasn't aware of the difference.The original 2.x's had two fans, one for the motor and one for the PEM. They were prone to failure, especially from road salt, and were replaced by a single fan (one motor with two blowers) plus a shroud to protect from debris. The upgrade was only done for cars in cold climates.
Thank you for this link. I'm going to look into pricing on this as my AC does not provide even cool air.A shroud was added to the front fans for 1.5 and 2.0 Roadsters to improve AC performance.
Cooling system improvement
