Re: Overheating at Low Speeds
Thanks for the suggestions everyone. Timing is set at 12 degrees initial, 34 degrees total at around 2800 RPM. Distributor is connected to manifold vacuum that adds around 10 degrees at full vacuum. Idle speed target is set at 870 RPM. My car has FAST-EZ EFI, and I haven't moved the idle AF ratio target from the default setting (I don't recall what it is). My car doesn't have gauges, so I didn't have a way to monitor the coolant temps until I upgraded to EFI a few years ago.
Couple questions - I've noticed there are a few gaps between the fan shroud and the radiator, especially where the shroud and radiator meet at the top of the radiator. Would it help to plug that gap? What would I use? Also, would installing a HD fan clutch help?
Thanks again. Hope everyone has a good weekend.
