Sorry for the new topic, but I need all the help I can get at the mo...

I'm trying to figure out why my engine gets so hot (M103).. I took it to the Mech. and we played with it. We noticed that under acceleration, the *bottom* hose would collapse.... and *slowly* return to shape....

What would cause this?

We've ruled out head gasket, because there are no exhaust gases present in coolant.

Clogged rad? Thermostat? Resevoir tank cap (rubber seal is peeling off and looks dodgy.)?

When I accelerate tho, the temp does drop (normal running 90deg and idle 100deg...)

I'm scared to drive her incase she overheats suddenly

Thanks,

Brian
