Hi guys, i wonder if anybody could help me

I renewed my radiator last autumn and refilled with coolant and water mix,
i bled the system properly and there are no leaks.

The thing is i can't remember where on the engine temperature gauge the needle setled when fully warmed up.

I know that they're not that accurate but mine settles above the half way line, it doesn't get any hotter unless i leave it standing and the fans come on when it reaches around three quarters but i can't remember if the needle was below the half line before the coolant change.

Where does your needle settle when warmed up ?

 

hey my bug stays at between a quarter and half and never moves

 

Yeah.. Same on my classic.

 

as above between quarter and half

 

Mine sits just above the 1/4 marker and only goes up very slightly even when giving the car 'the beans'.

 

Never more than a half

 

'05 STi and its always about 1/3 on the dial no matter what i've been doing!

 

This is what i seem to remember before my rad change but i couldn't be sure.
There's no air in the system as i keep checking because of this uncertanty.

I think i'd better change the fluid again for one that is complete rather than adding water to the mix.

Any ideas on what's preferable ?

 

I don't think changing the anti freeze mix would really change things, as when I was initially running in my engine it was on neat water and even when anti freeze was put in it didn't make a difference.

The additives in the coolant mix are mainly for not freezinfg (obviously) and to stop aluminium components from corroding.

It sounds like you have another issue.

 

Thermostat maybe ??????

 

You would know.

Sorry I coudn't resist.

 

Ha ha ha

Not sure "Offically" though

 

as above the thermostat.......get a 72c one......should have no dramas then.......after fitting that and temps are still up then there is an issue

 

Thanks for the info guys, i'll get a new stat and try that.

Don't worry me with head gasket worries Ty,there's been too many of them with this club lately.

 

Sorry Marc I wasn't getting at it being a HG problem, I'd be more suspicious of the thermostat or the radiator itself.

 

I hope it's the Stat for you Mate - lesser of all evils. I got an uprated High Flow Stat from Advanced Automotive - a reasonable 16 quid delivered I think it was - have a check on the site
