Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

The standard rads are the same one's used on the GT3/GT3RS so are more than up to the job of cooling a standard C4.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Can anyone advise me of the dimensions of the Radiators on the 996 C4 please? I am contemplating having them replaced with upgraded Rads, made by a company who specialise in Touring car and F1. These will be lighter than the original Rads and more efficient. P.S The have just done an exhaust system for me and it is incredible, great sound, great look.

POST 2Original post

Its hard to give demensions as you need more than the length/width/depth of the radiators. You also need to know where the pipes are sited, their dimensins and fixing points. Here is a link to start with http://www.eurocarparts.com/ecp/c/Porsche_911_3.6_2004/p/car-parts/car-cooling-parts-and-car-heating/cooling/car-radiator/?203330230&1&94f91955a85ca9598cd57f5de740f23cc432d725&000261 but try going to the Behr Hella web catalogue for more info. If you are getting the rads made, it is probably as well if you can find old knackered ones cheaply for them to use as a template.

POST 3Original post

Unless they are cheaper I wouldn't bother. The standard rads are the same one's used on the GT3/GT3RS so are more than up to the job of cooling a standard C4. Design 911 do standard rads starting at £87.50 for OTRAC then £123 for the same Hella ones Porsche use. Design 911 Radiators If you really want some extra cooling then it might be worth a look at the way Porsche do it. That's to add a centre rad (see the Design 911 link above)

POST 4Original post

Hi. The rads are: width 490mm, height nominally 310mm (of the core), 350mm from top to bottom of the galleries, at their "slim" point, and 390mm top to bottom of the galleries at their biggest point, which is at the hose connections. So overall height is 390mm. Thickness is 45mm. On the front of the rad are four fastener bosses where the air con condenser attaches. The bosses are 355mm apart (centres), horizontal dimension (width), and 335mm apart in the vertical dimension (height). These are measurements from my 996 turbo but I think the rads are the same dimension as your C4. Best of luck.
