Worth changing? im fitting a new alloy rad, hoses and doing throttlebody bypass mod, whilst the coolant is drained is it worth replacing the thermostat for a new OE one whilst im there? or a cooler running one?

Car has done 88k and is standard power until remap later this year.

 

i would defo change save you the head ache if it went funny later mate zero sports 1s are good but pricey

 

Thats what im thinking, its £55 for zero sport Cooler stat or £28 for subaru one from dealers, is it worth the extra £25? seems a lot for what it is?

 

Got a brand new standard stat here

 

Definately replace now rather than having to do it all again later. Go standard new replacement. No need to run cooler ones on road cars.

 

Deff. look at a new stat...One that fails and stays open, not closed. The Z/S one and Grimspeed one both do...
Grimspeed one is only $50, looks like the seal they provide is a bit crap though...

cheers need it for thursday though latest, so that grimmspeed is a no go. Seems people are split over OE or Zerosports cooler

Do the Subaru ones stay shut if they fail then?

 

Before spending big money, I'd ring a couple of local motor factors. Probably get a decent one for under £10.

 

Euro car parts have one £16, Facet Thermostat? will the quality be same as subaru one?

 

Also i used carplan blue antifreeze last time but local place only stocks comma

They have

Are these suitable? subaru near me use shell but dont have stock to sell me

 

Yes, Subaru are unlikley to make their own as it is. And VERY unlikely to use a dear one.
Even the window switches are branded, "Nissan".

 

nice one cheers, anyone help me on which coolant to buy (as posted above)?

 

You can use virtually ANY decent modern anti-freeze, just DON'T mix the types. It can cause sludging and waterway blockage.

Mine came from a local factors, not dear, suitable for an alloy engine and with corrosion inhibitor.

So either of the above would do.

 

Reading about and it seems newer OAT antifreeze can cause problems in older cars with heater matrix, destroying seals, gaskets etc

 

Be careful when buying the pattern thermostats,when i was buying,some of the pattern ones are smaller than the genuine one and also the seal can differ in thickness,some pattern ones do not come with a new seal either.

i opted for the genuine one and seal for £25,seems pedantic but it wasnt a job i wanted to do twice for the sake of £10 difference

and yes,the new OAT stuff can froth up in classics and cause issues,if you have a 2001 onwards impreza,you should be o.k with the later antifreeze

its a MY00 classic, currently got Standard blue 2 year stuff in but most places locally only stock the newer types i linked to?

 

2 options,

1.retain fluid lost when removing the pipes/stat etc, i also removed the rad,found it easier to then
2. buy the proper stuff and re-do the antifreeze at a later date,local halfords ?

 

dont want to use old coolant as the rad is damaged by a big stone so crap might have got in it.

I looked at halfords antifreeze but it states
Silicate (IAT)based Standard technology

Subaru recommend an anti freeze that is free from amine/phosphates, silicate and nitrite.

 

Halfords is a no-no for this sort of stuff, unless you have a spare arm and leg to pay with

Look up motor factors on yell.com

 

Cheers located a comma stockist now that i didnt know even existed, only 6 miles away so will go in tomorrow.

If anyone is after a decent alloy rad coolpartsuk on ebay supplied mine and its fantastic, loads better than the standard rad!
