ok I should have put more info in my post...
The engine is in my ae86 (not standard
) and was put in by a workshop, at first it over heated because it had the standard single core radiator. It now has a bigger radiator and gets too cold when going 100kph. The obvious thing would be that the thermostat was stuck open.
This is when I found that the thermostat is mounted in the bottom radiator hose with two back to back housing covers, (which i thought was strange because most enigines would have it just b4 the top hose (hottest place)) the mechanic had drilled two small holes in the thermostat so it would work backwards.(?)
Note: I assume he put the thermostat in a "custom" housing, further down the hose, is because you wouldn't be able to use the standard thermostat position?.....
So this is the strange part, I would have thought if having it in the bottom hose was a problem (because water is cold), meaning it
shouldn't open, causing over heating.... but it does the opposite.
What it all boils
down to is that i need to find out why it isnt controling the temperature even after i put a new thermostat in!?
*wonders if anybody understood that*
