D2a Coolant Overflow Reservoir

**Vinnie** · 11th December 2021, 12:07 PM

Hi All,

My coolant overflow reservoir (good old plastic one) has split, this is the second one I am on. I've been told that the aluminum replacement is the way to go. Is this a better option? If so what brand/s should I look at? There are a few out there but have read reviews about those failing as well and just want a bottle that's not going to give me grief.

Cheers,

Vinnie

I run the allisport one and it's fantastic and lifetime warranty too

X2 on the Allisport version
I've been changing a few out recently , these rolled up the other day. 2 are the power steering reservoir
I get the in built low coolant float version... spot on.
Twice the price of a genuine replacement but well worth it

Edit : The blingy cap finishes it off, the tank I've linked to will suit the car in your signature

Hey, you weren't supposed to open that until Christmas!

I should have told the owners that, but it was more like " can you fit them up ( including spst relay, buzzer and led ) before christmas...please.

OK , one's mine (P.S. reservoir) probably the only one that won't be fitted before Christmas

I am toying with the idea of getting one of these. I see the tank with the float switch only comes with the float switch.

Where do you get what is needed to set up the low coolant alarm?

Dave, I got a loud, audible alarm from Jaycar, it's not much bigger than a 50c coin.

But don't you also need a bit of electronic trickory to go with it?

Not really.
the switch in the expansion tank is on or off.
the alarm or led indicator just shows you that the switch is on(or off).

with one wire on the switch connected to earth, the other wire needs power from somewhere, (eg. battery), other wire will go to alarm/led and the other wire from alarm/led will go to earth.

As Ian mentioned, Jaycar will have what is required, I use an spst relay and use the relay earth circuit for both wires from the switch, it's just a personal thing which avoids feeding another powered wire through the cab.

Arthurs previous answer appears to have 3 wires involved or direct short when switch is closed , maybe I'm just not understanding correctly.

A simple method would be this , but don't forget to run a fuse
