Check all the above and look into changing to a Tectalloy 90 or 100 ready mix.

You will required 2 X 5Ltr bottles of coolant Plus 2ltr demineralised water, if you want to do a full flush and fill. I did mine a week ago and now the temp gauge is steady at just a whisker above 1/4 mark.

ok couldn't smell any exhaust gases while running so bit of relief.

whats the best way to dump all the coolant from radiator and block without to much trouble? is there a drain plug underneath or just pull bottom hose off?

You won't smell them mate. Unless the gasket is totally furked. You will need a little pump with testing fluid in a couple different chambers. You pump it over the open resiovouir at operating temperature and the liquid changes colour if exhaust gases are present.

99% of mechanics will have these and shouldn't charge anything to test :)

My bad should of explained better.

Ok well I put a Nulon radiator flush through dumped it then ran fresh water and dumped that finishing with a 50/50 mix of Nulon coolant.

Hopefully never see that brown sh*t again.. didn't smell to healthy either :stinker:

good to know, mine has gone to an odd brownish colour which does look terrible. I remember when the car was new it was bright green and healthy looking.
