Water/coolant usage?

GrimR33per · May 27, 2012, 02:31:45 PM

Is it normal to have to fill up abit every time you check?
As I fill it I can see it go down and not stay at cap level? I can\'t see any leaks so jut wondering, thanks

Mine does the same dude, dont worry about it unless your overheating and water is pouring out the expansion tank

Only heats to around 92, 93 after I stamp my foot a few times lol. No real water loss but is it ok to keep topping up with tap/ bottled water?

Have you checked the seal on the AST etc? sometimes the seal gets old and doesn\'t fully seal meaning that when it gets up to temperature the extra pressure can mean it leaks slightly.

Yea seals fine. Just went to check the water level again and it goes around an inch lower than the small hole. ?

Coolio, so to confirm. That is not for ast but for the other, lol. Thanks

Yes mate. easily mixed up as they both fit on each other and then you will lose coolant....I dun it !

Right, purchased...
Just checked mine and it must be standard as its just the cap and a rubber seal inside.

Hopefully it sorts it but if not what would I be looking at then? As thinking of it, I have had to put quite abit in altogether and as said I can\'t see any signs of leaking?

noted that cap on ebay is 1.3bar :o sure I read somewhere 0.9bar is better for the FD :confused:?

I got it on mine no problems, solved my disappearing coolant....
Yours could be loads of things, standard rad?

Try not putting water in and firing it up from cold, if the buzzer goes off then shut off and top up. It doesn\'t always sit at the top of the neck but sucks coolant in from the overflow tank.

Have you changed coolant recently ? It could just be burping the air out of the system.

Just keep an eye on it !

Took to work today and buzzer went off when I got in the car so had to top up quite abit. Ast was very low also.. How low is the coolant buzzer??!

Ot home now so im going to have a nosey round. W temp at 85
I cant see any puddles as of yet so will wait till water goes over 100..

Any suggestions though? It went back into pip as the water pipe round bulk head split and he\'s put a hose round it which I\'ll try and look at as I can\'t see it..

It shouldn\'t be using the amount I\'ve had too put in that\'s for sure
