Feedback:
"Kit received and it looks awesome! Thank you so much for the deal!"
"Very quick delivery and well pleased with quality of items delivered, many thanks!"
"Results were good and I see lower temperatures than standard cooling system. Success!"

Illustration of it's purpose:

General info:
Parts have been professionally machined from aircraft-grade aluminium alloy with excellent corrosion resistance. More info about reroute purpose can be found here: http://coolant-reroute.com/ and in this topic: https://www.mx5nutz.com/forum/index.php?showtopic=89997

Few hints and tips:
- installation requires you to move the charcoal canister a few centimetres aside, or you can remove it altogether - the removal is very easy and there are many guides available online

- in case you have EGR system on your car, you will need to delete the EGR (I have the blanking kit for £15) or modify the EGR pipe
- install the thermostat with weep hole facing the top (upwards)
- for VVT engines (Sportive) use a non-VVT head gasket
- don't delete the heater core as it's wise to keep the coolant flowing, unless it's a track car

Basic kit - £89

A.) For engines with fan switch in front of the engine (1.6 NA - http://diy.icydesigns.com/i/368-p2.jpg)
B.) For engines without fan switch in front of the engine (all except 1.6 NA)
C.) WIth core plug (regardless of the engine), if you want to freeze plug the outlet - parts needed are included

Spacer options (included in the price):
1.) Standard (stock heater, stock gauge)

2.) Standard with 1/8" NPT thread for additonal temperature gauge

3.) Heater delete (no coolant outlet for heater hose) and 1/8" NPT thread

Hose: Gates 22436 rubber hose for £29 or you can design your own hose connection (e.g. if you want silicone hoses).

Housing: you can use a 1.6 NA housing or get housing from me - used for £15 or new Kia for £22 (1.8 NA/NB and 1.6 NB housings cannot be used).

Thermostat: you can keep yours or replace with a high flow stainless steel thermostat for £12, either 88°C (OEM) or 82°C

did any of you take a pic of what you filed flat as I have the engine out at the moment and will be doing this soon

Well I didn't

however it is easy to sort and you have the advantage of easy access with your engine being out of the car! When you offer up the spacer, you may only be able to get the top bolt in as the bottom of the spacer is fouling on the top of the bell housing. I machined (read, used a flat file

) and took off approximately 1.5mm to form a "flat" at the bottom of the spacer about 25mm long and the full widths of the spacer, that's all it was. If you look at the spacer, the heater hose take off will be at 9 o'clock position viewed as from the rear of the engine, the "flat" will be at 6o'clock, plenty of meat on the spacer at this point and does not encroach on the bolt holes or anything else so no big deal. Easy when you have the part in your hand to look at.

I had to do the exact same thing, filed down the spacer and the gearbox

dolphinboy · Jan 6, 2015

ok cool sounds straight forward even for me

I need a kit for my 1994 1.8 turbo but I'm utterly confused

SkidNation · Jan 12, 2015

Issue with clearing the gearbox has been resolved for all reroute kit orders since now.

2 mm of material is removed from bottom of the spacer. My apology for all those who were affected.

For 1.8 you need the "B" kit. What exactly can I help you with?

Henz Powell · Jan 17, 2015

Question about the front fan switch in the blanking plate. What's the tap thread specs for it? I need to make a thread for my blanking plate and have no idea of the sizes

Which kit for mk2 1.8?

Thanks Tom

Kit B?

SkidNation · Jan 20, 2015

Tom: yup, that is correct.

GTuff · Jan 28, 2015

What thermostat do I need to use whisper? Or will the oe one be fine?

SkidNation · Jan 29, 2015

OEM is not the best option as it's very tricky to fit it with temp sensor. It's possible, but personally I use (and recommend) getting a one-valve type.

Does that mean use this one:

Rather than this one:

SkidNation · Jan 29, 2015

Exactly

But as I said, you can try to fit your OEM and only order new if you experience issues (weep hole must be at the top, or very close to the top - from 11 to 1 hour on the clock).

There is nothing wrong with one-valve thermostat if it's a quality product, for NBFL Mazda used it too (http://www.mx5parts.co.uk/thermostat-genuine-mazda-mk25-p-1545.html).

Btw. I just finished working on simplified installation guide for reroute kit: http://coolant-reroute.com/installation.html

mmmctavish · Jan 31, 2015

Got mine - spot on. Thanks for extra

zoona · Mar 24, 2015

Possibly old info, but people seem to have been going to odd places for the Kia thermostat housing.

Just ordered it from my local Kia dealership and they can get it next day for £22.09. (part number 0K24715172A)

Which kit do I need for my Mk1 1.8 1996?

Kit B?

Cheers

Mark

SkidNation · Mar 27, 2015

Hi Mark, you are correct, B kit is the one for your car

Badmuts20 · May 9, 2015

What is the change what is made for the new ones?

I think I have a leakage at the reroute. and maybe is this the solution.

Its a 1.6 with 5 gear.

SkidNation · May 10, 2015

Hi, the small change only took off about 2mm of material at the bottom side of the spacer to clear some of the gearboxes. I'm 100% sure it's not related to your leakage.

Suggested troubleshooting:

check the hose connection(s), on some of them I even used two steel hose clips to have it extra secure
check if the coolant outlet barb is tightened properly
the last thing can be leaking gasket, if you didn't have the engine out while installing the kit it's very tricky to get it there right without damaging it

Stuntman · May 10, 2015

Hi whisper, what kit would need,

Mk1 1.6 1997

Also his do I order and pay etc?

SkidNation · May 11, 2015

Hi,

for your 1.6 NA you need the "A" kit. I've sent you a PM about the order.

Cheers,

Samuel

lethal_ghost · May 16, 2015

I need one for my 1.6 na

ecksjay · May 18, 2015

Hi mate, I'm assuming a 'B' kit is the one I need for mk2 1.8? Not read through what else I need so I may pester you with messages. Engine is partially stripped down so should be fairly easy. Thabks

SkidNation · May 18, 2015

Hi, yes - B kit is for 1.8 engines. (Hopefully) everything what you need to know is in my first post in this topic.

gtabomber · May 31, 2015

On a 1.8 NA with coil-on-plugs can i use the 1.8 thermostat housing as the coil packs arent in the way?

I guess the mk2 thermostat you linked fits the mk1?

Cheers
