If mine ever goes south I’m going back to oem myself

[QUOTE=Hotrodz;3717451]I have been running the oem radiator as recommended by my TT installer since day one just over four years now. I never had an issue with temps until I started tracking the car and Sebastian at Specialty Z and I discussed my options which did not include either of the two aftermarket radiators mentioned so far. The only one that he felt had any real merit was the Ron Davis custom radiator for the 370z. It requires modification of your front engine bay and you have to delete your AC. He suggested I open up my front bumper to let more airflow in before spending significant dollars on radiator change. So far that has worked even on track days over 100*.

The other thing you need to consider is that those aftermarket radiators are thicker than the oem and don't allow as much space between it and the intercooler therefore despite the other issues you may not make much headway on keeping your temporary down. Long story longer...stay with your oem. Just my two cents worth of nothing lol!

This is good advice. So need for CSF or Mishimoto junk on a boosted car.

I'm currently on my third CSF radiator and this one is the updated version. It's been installed now for 3 years and started leaking about a month ago. I'm officially giving up trying to have an aftermarket radiator in the Z and will return it to stock very soon. I will say, when I notified CSF of my second radiator's failure they did replace it for free, as it was not the updated version. As much as it would be awesome to replace this one, I am just ready to not pay for a radiator install anymore.

I'm totally with you. If CSF had contacted me and offered a new revised one, I may have bitten. However, they were nowhere to be seen even after contacting them. So BAD CS and BAD PRODUCT = suck.

I totally feel you on having to replace it over and over again. That's why I said "revised" product. The down time and uncertainty of driving a non reliable car is not worth it.

Here is the another thing to consider as some unfortunate folks found out. Unless you water temperature spikes while you are losing water you will never see a change in water temperature when the tank has gone dry....because the temp gauge is reading the ambient temperature and without warning your engine goes boom!

One of the reasons I installed an aftermarket water temp gauge. The sensor is in the upper radiator hose.

Me too but boy was it a ********** to get that silicone hose on with the fitting in it.

Here's mine.

Yeah I need to get that and an oil pressure gauge.

What size is the inline sensor adapter?

Thanks Rusty!

This is not just for the 370z, it is for many other cars also. The 300zxtt and 300zx from 1990 to 1996 were the same way.

That’s the one
