How noisy are the Mishmoto fans? Looks like an easy enough replacement job from the video on YouTube.

It will be the fan motors, if you confident you can refurbish the motors, but most just replace them with the mishmoto fans.

Hi Ricky,

Can you believe the garage hasn't sorted the problem yet! I got fed up with them and just took my car back today. Looked into the issue in more depth... My previous diagnosis seems to be wrong as neither of the fans are coming on with or without aircon and the temperature slowly climbs on idle. Any ideas on what to check next. Just checking out the fuses now

If the garage are trying to bleed the system using the built in bleed screws,and cant get any coolant out then it sound more like the system is air locked, there are several threads on this problem, so if you do a search, you can either DIY or tell the garage, who should know how hard some cooling systems are to bleed,

Do this before proceeding any further ae you need to get to the bottom of the problem before throwing silly money at it by just wading in and replacing the water pump, which may be unnecessary,

I would take it to somewhere that knows more about Zs.

I don't know what they have checked. One fan turns on with aircon.

As in the title, where do we all take our zeds? In my experience certain garages shy away from these cars and I've had some hit and miss work done. Mine has just started overheating and the garage I use are claiming it is the water pump but said that would like me to take the car away if this is the case as it would be a big job So... Any garage recommendations?

The garage said they tried bleeding the system and no coolant came out at all and that that was the reason they thought it was the pump. I shall ask the garage to check the rad hoses as you suggest.

If the thermostat has been replaced or removed, you can check with either, and its still overheating, then its more than likely the fan/s if only one is coming on with the air-con switched on and the engine up to running temp, the its definitely the fan, its a well known fault, the fan motor brushes get stuck/worn and can be DIY fixed if you know what your doing.

 

I would first eliminate these before letting the garage charge you big money for replacing what probably a perfectly good water pump, you can also test this by letting the car warm up and seeing if the bottom rad hose is hot or cool, if cool it likely to be the water pump, although unlikely IMO.

So the garage thinks the water pump is at fault, is this a big job? The garage said that it might involve taking apart the font of the engine and that they don't want to carry out such a complex job as they are very busy atm :s

Okay so one of the fans turns on eventually with the aircon. So I think it is the thermostat as still no hot air in the cabin. Am I safe to drive to the garage at speed so that there is airflow over the radiator? Or is a replacement thermostat a simple enough diy job?

AC on doesn't turn on either of the fans. I am suspicious because of the steam coming out of my coolant tank ha ha. New symptom... Whilst driving and climate control on hot it still comes out cool

You say the dash is showing the temp as fine, so what's making you suspicious? My gauge shows a bit under halfway, I occasionally hear the Mishimoto fans come on if in heavy traffic. If the stat was an issue (i.e stuck closed) the temp would continue to climb.

The best way to check cooling fan function is to turn the ac on, if fans don't spin its a fan issue. However from what I've seen the temp gauge should have gone into the red before boiling over.

So it happened today in stop start traffic, go figure. Fans don't appear to be turning and dash is indicating that the temperature is fine. Is this an obvious thermostat issue? Coolant level is fine, in fact too high for my liking even after spewing coolant out the overflow pipe. Hate to see boiling coolant in my baby Any idea what the issue could be?

Just got back around to this. I googled but couldn't find the name of this autoelectrician. Would really like to sort out the speakers soon as I've been lacking decent sound for so long!

Good choice 😀 welcome to the family

Just received this beauty from Ewen at Clark Motorsport. Very quick delivery and Haribo was demolished in seconds! Nice touch getting it fitted on Tuesday so will provide a bit of feedback sometime after. I'm sure the garage will be happy enough as the quality is very impressive, this is a well made bit of kit! Plus the girlfriend likes the colour

Hey guys, unfortunately I won't be able to make this one after all. I hope to see you all at the next meet, have a good one!

I soundproofed my boot with Dynamat and put a rubber carpet underlay and a foam carpet underlay in my boot. Didn't really notice much of a difference.

 

I have had a cobra resonated set up on teh car from when I brought it (not sure how old it is). I've just put a new Cobra back box on and the noise is greatly reduced but its only ~50 miles in.

 

My old back box would drone 2500-3500 which is pretty hard to push through unless you want to hoon all the time.

 

One thing I've always wondered is if changing the cats and the Y pipe from OEM would make any difference to the cobra drone.

Good to know the soundproofing hasn't made much difference, saved me a job. I can only imagine changing the cats and Y-pipe would make the drone louder. What actually causes drone anyway? Is it just the resonance in the cabin or does it sound droney outside too?

I think you will find most aftermarket Exhaust will suffer drone at some part of the rev range. Personally I would adapt your driving style to punch through this part of the rev range rather than throwing money at trying to reduce the drone.

Yeah I think this has to be the way forward for now

Ok so a 1000 mile + update...

Sound has stopped changing and I assume it is lovely and carboned up inside. Although it sounds wicked, unfortunately it has definitely got a pretty annoying drone from 2000 to about 2600 revs which is a shame because this is the sole reason I got the resonated over the non resonated.... God knows how bad the drone is from the non resonated! As a daily driver this is a bit much but perhaps can be improved by some sound proofing in the boot and bulkhead? If anyone has any idea how to decrease drone other than avoiding that Rev range completely then I am all ears.

Cheers guys

Hey man have you spoken to the garage just behind the pasty drive through next to the car wash and valeting. in pool? Heard good things about them there

No I haven't might check them out

Hello,

I'm on the lookout for a decent autoelectrician down Cornwall way to connect up my aftermarket HU to a Pacroem-nis2 adapter.

If you know of anyone (preferrably if they have worked on a Z before) then please let me know, i've been missing that bass oh so terribly

Cheers,

Glen

Why not buy an ARK DUAL GRIP ?

 

 

Because it's out of his budget?

 

 

Have you checked out the ISR Single exit? Awesome sound for the a great price £300ish I think.

Scorpion is just too quiet.

 

Many people are satisfied with their Invidia exhaust.

Cobra is another contender in your budget - Although the ISR single exit sounds very similar for a fraction of the cost.

Cobra, bloody great sounding exhaust for the price

I would recommend using a fair bit of that budget purely for purchasing the exhaust and try to fit it yourself. I had never done any real mechanical work before my 350 and found it really simple to fit my exhaust just on small ramps on my drive

 

Either way, hope you find something you are happy with!

 

Thanks for the advice guys. I think I am swaying towards the Cobra Resonated with rolled tips, should do the job I may have to replace the cats as well soon as I spotted one of them had a hole.

 

Is the hole not just in the heat shield though ? If so no worries there until they start rattling and then you could just rip the heat shield off as many have done. Or like me found it the perfect excuse to get some Berk hfc's.

Hmm perhaps the heat shields are making those rattling sounds that have been annoying me no end! Anythin else likely to cause a rattle below... no more puns please this is a clean thread

Exhaust Update!!!

Cobra resonated exhaust is fitted and supplied by Cougar Store (thanks again!). When first fitted it sounded very muted and dull without the crackle and pops but within a short drive (20 miles) she was sounding wicked! (I assume this is the carbonation inside the exhaust which is stated to take up to 1000 miles). She is a bit droney between about 2000 and 2500 revs but I am hoping this will subside during the 1000 miles, or else I will have to change my driving style and keep more towards the redline

Whenever I reach 1000 miles I can provide an update for anyone who is interested, but for now I am definately of the opinion this was a worthwhile purchase. Can't get enough of those crackles, who needs an F-Type!

Thanks ZedMan, I don't know why I wasn't notified of your reply but I've only just seen this. Exhaust was fitted by Blowing House garage in Penryn, they did a neat job and a great service.

My next thing is that I need an auto electrician for fitting my Pacroem HU adapter. Any recommendations for a decent Autoelectrician nearby? Cheers

I've heard about this mystical place.... But yeah a bit out of the way for me.

Hey guys and gals,

I replaced the bose HU and have bought the Pac-Roem adapter but that is where my experience ends... Can anyone recommend a decent autoelectrician in the Cornwall area, preferably who has worked on a 'z' before. I'm missing the sub very much

Cheers,

Glen

Old thread but since a few of you are in the Cornwall area I have a quick question. I have a cobra resonated exhaust on the way and does anyone have any garages they can recommend in the county? Cheers!

Thanks for the advice guys. I'm not a fan of the single exit exhausts compared with the dual, especially when the stock bumper has been designed for 2.

 

I've read that the cobra is quite quiet?

 

Definitely not quiet especially if you go for the louder of the two.

I've watched a few more videos and I agree, though would be worried about drone from the non-resonated version. Has anyone experienced drone with the resonated version?
