CSF Radiator for G37 Automatic

Project G37S Transmission Upgrade Part 1 – Cooling Upgrades

 

Compared to OE the CSF radiator is .1” thicker than stock according to the electronic caliper.  Volume capacity seemed a little greater with the CSF unit, but it was hard to get a back-to-back volume measurement of the CSF vs OE.
CSF Radiator install for G37
The CSF 2-piece radiator and A/C condenser combo drop right in without any fuss. Excuse the blurry photo. It was just after this point we busted the high pressure AC line for the new condenser and we had to run to Infiniti for a new hard line. Oops.

 

 

G37 specific hoses made by HPS made from multi-ply premium grade silicone and reinforced with high quality polyester enabling the hose to withstand higher temperatures and pressures if needed.

As noted in the previous page, we had witness marks of coolant weeping from our factory hoses.  So it was time to replace the radiator hoses. We went with HPS Performance Products as they offer custom fitted OEM replacement silicone hoses made of a 3-ply reinforced high temperature material that exceeds the SAEJ20 standards. The HPS hoses also come in your choice of 3 different colors: black, red and blue. We thought a contrasting red would be a nice presentation in the engine bay so we went with part number 57-1049-RED.

Here you can see the multiple layers and reinforcement of the HPS hoses.
To ensure we didn’t have any air-pockets in the system we used this Lisle spill free funnel. There are all sorts of adapters in the kit to fit your cooling system. We turned the engine on and let it run for about 10-15 minutes to allow all the air bubbles to escape. There’s also an extra stopper so the remaining fluid can be put in the overflow tank or back into the jug of coolant.

  1. Can only speak from our experiences, but our 370Z Project had the CSF radiator/condenser combo for a year and a half without a single issue. It was then outfitted with the CSF triple-pass radiator and that has been on the car since 2014 – also with zero issues. Here are the links to those articles:
