Difficult as the stock doesn’t give an accurate temperature.

Thank you, I will have a think 

Stock gauge is still there and as far as I know still hooked up to the OEM sender. It goes to just below halfway and gets there before aftermarket gauge gets to it’s fully warmed up temp 

Thank you, that would be great.

Yes aftermarket gauge fitted in the cab, still have the stock one as and that is steady at just under halfway.

Would generally the top hose temp be less than the rear?

Ah took ages for the garage to get all the air out of the system when changing the radiator so might leave it for a while

Cheers

I've had similar issues recently, are you certain of what make/ model of thermostat you run?

 

I replaced a stuck-open OEM thermostat recently with a Mishimoto 68* thermostat. I found my temps were reaching only about 70* when normal driving, a bit less on faster roads and a bit hotter on slower ones with less airflow. When coasting down a hill temps would get as low as 62* so I don't think Mishimoto's claims of it opening at 68* are exactly accurate. I assumed something was wrong with it and to their credit they sent me another after I described my issues. Exact same temps, no change at all.

 

I replaced it again with an OEM-style Motorad thermostat and temps are now bang on with temps sitting in the 80's while cruising.

I'd say your issue may lie with the thermostat.

Sort, I believe I bought an OEM one but was off eBay and not from the the UK. Maybe it wasn’t the bargain I thought it was…

Any easy way to test it?

Normal temps are I believe around 90-95 . I'm guessing that's a aftermarket sensor? 

 Yeah it’s an aftermarket one, recently installed although previous reading was similar 

Thank you.

is 70dg definitely too low for cruising? You can see location of sensor below if this makes a difference 

I don’t drive the car hard at all 

I’m sure it is but still want to replace it with a standard pressure one if possible.

Yes along with water pump 

It’s been fully bled by a specialist so should

not in theory have air in the system 

Not if it is the high pressure cap but it’s running a bit cold (crusing is 70dg)  / coolant doesn’t seem to expand when hot and heating isn’t brilliant.

Hi,

I have the above installed on my DE along with the Koyo high pressure cap but I think this is causing issues.

The OEM cap doesn’t fit and Koyo only supply high pressure ones.

Tried to google alternatives and sought the help of Torqen without success.

Is anyone else running this radiator?

Thank you!!

The lugs seem fine. 

Just tried again even with downward pressure it won’t budge past 3/4

The Koyo goes on with ease 

Cheers

I think the high pressure Koyo Cap is causing me issues so trying to find a standard one that will fit 

Hi,

Im trying to replace my Koyo high pressure radiator cap with a OEM Nissan one but doesn’t seem to fit right. It won’t twist all the way round like the existing one does

My car has a Koyo Aluminium Racing Radiator if that means I need to stick with the Koyo cap? 

Thank you 

Definitely have an issue then.

Thank you 

Hi,

I’m not sure if I have an issue or not.

At the idle the heater blows luke warm air but very hot whilst driving. No other temperature issues.

How hot should the heater be at idle compared to driving?

Thank you 

 Just had my 06 Rev up on the Dyno at Horsham whilst having some other work done.

Does this look normal and healthy? 
 

Car has induction kit and RSW Exhaust system

Cheers

Hi 

My 2006 350z has recently started blowing cold air whilst idle and even when moving it wasn’t as hot as it used to be. 
 

Today at the end of a 30 minute drive the fans came on and didn’t go off, the stock temp gauge moved to the middle but my aftermarket temp gauge was at c85 and normally fans don’t kick in until 95.

Other things which maybe related;

Squeal from the engine bay (sounds like belts)

Aftermarket oil temperature gauge has been bouncing but when settled reads normal

6/7 months ago it has a new radiator, cap, hoses and thermostat 

Any help would be appreciated

Thanks Coz, I appreciate the reply

I will remove this weekend and see if I can see anything 

Hi,

Sorry for the noob questions but I want to replace my cone filter. Do I just unscrew the existing one at the end and screw the new one on? Also how to I figure out the size, measure the intake? 

Thank you!

Thanks Olly.

Yeah probably do what you said but just found out my Greddy oil cooler hoses are leaking so will put that to top of the list

Thanks Paul.

Do I need to make any modifications to put the original back? Car has some expensive mods so surprised they would have changed it if original is better unless it was just for sound?

Thanks Jack appreciate the reply.

Yeah happy enough with it at the moment and car is definitely on the loud side.

Can I just replace it with any cone filter or does it need to be a HPI one?

To be honest I haven’t as I have zero knowledge on so any suggestion would be appreciated!
