[/quote]My newly acquired 99Turbo runs hot but doesn’t overheat it’s been many years since my last Turbo so I have a few questions I hope you can help me on .
It’s runs part way between normal and hot on the gauge but mainly towards the upper end .
It has Evans waterless coolant I’ve been told this can make it run hotter? Is that correct.
I have spotlights fitted could they be restricting airflow ?
Should I change the stat and put a 82 dg one in ?
Is the airflow to the oil cooler restricted by the Saab sport bodykit as the standard front spoiler has a much larger opening .
Is it worth investing in a alloy radiator with a larger capacity , has anybody done that and are they available ?
The electric fan is working ok and cuts on and off but does stay on most of the time.
Any thoughts .[/quote]
I would try an engine flush and use regular coolant, like you have suggested and see how you go on. Change one thing at a time!!
Then remove the spots.
If you have or have access to a thermal camera I would give it a go, it will show up dead areas in your radiator. I can do this for you, where are you located?
Changing your radiator for a larger alloy one will not help and will just cost you more money. The original rad has copper tanks etc and is more thermal efficient. If you radiator is of the old type (less efficient fins) it can be re-cored for about £120 ish, with a modern core and better finnage....I think I have just invented a new word

.
Another good modification is to alter the passenger side radiator hose, to the bottom of the radiator, like on a 900 (that is why they altered it!) this will then force more coolant across the whole of the core and not just accross the top, you will need another top pipe to do this, the rad shop may have or you can butcher an old radiator, then you will need a 900 hose to attach to couple it all up. Also bear in mind you may need an alloy header tank with a small nipple to come off the top of the rad, otherwise you will get a small dead spot, just where you fan cut-in switch is situated.
