smiffy 99 Report post Posted May 28, 2012 right everything might be allright but i'm a bit worried. car starts and drives fine doesn't loose water and using the same amount of oil as it always has. now the problem is that if i drive hard and then stay at say 80mph the temp goes right past 90 and stays there (red light doesn't come on). it then takes ages for the temp to go back down to 90. it will sometimes rise back and come back down. all the hoses have been replaced with silicone ones. now could the rad be shot or when the cam belt was done last someone never changed the water pump for a metal one and that is shot or something else is shot or i'm just worring about nothing. Just thought that the temp should stay at a constant 90 when driving any help would be good ta Quote Share this post Link to post Share on other sites

smiffy 99 Report post Posted May 28, 2012 but it does it all the time, rises falls rises falls rises falls, surely an airlock would just overheat straight away and the red light comes on. if it is how do i get rid? Quote Share this post Link to post Share on other sites
jhc 28 Report post Posted May 29, 2012 Air locks can move around. If its where the sensir is it will read hot. If it moves it wont. It may not be, but as you've had the cooling system apart recently to fit hoses it would be my first suspect. Not sure on the bleeding methods for these cars, do they have bleed nipples, are they 'self bleeding'? Quote Share this post Link to post Share on other sites

Smaky 73 Report post Posted May 29, 2012 I suspect there's nothing wrong but pluging it in to live diagnostics would show exactly what the temp is, at worst here I would think it's a fan resistor for the low speed fan or the radiator is just a little past its best before date.

smiffy 99 Report post Posted December 3, 2012 I can get the cams, I've seen them against new ones Why ? don't you think they needed changing. The lifters where fooked aswell Quote Share this post Link to post Share on other sites
Smaky 73 Report post Posted December 3, 2012 I can get the cams, I've seen them against new ones Why ? don't you think they needed changing. The lifters where fooked aswell It's not whether they are worn or not, but where all that material which has worn off them has gone, normally it makes its way to the sump where it ends up having a nice munch on the big end shells, if it's simplys who are doing this then I'd certainly be after garentees for this possibility.

Smaky 73 Report post Posted December 3, 2012 And cams don't wear down for no reason... I'd be trying to find out why? Low oil pressure? low oil? Or is it just that the coating has worn off as they all do on the mating surface. Quote Share this post Link to post Share on other sites
smiffy 99 Report post Posted December 3, 2012 theyve dropped the oil and changed it, suspected wrong oil used at some stage. its done 117,000 miles anyway Quote Share this post Link to post Share on other sites
