Hey guys I have a 90 Civic DX w/ 156,000 mi, and when it's cold outside (like teens and single digits) it takes forever for the engine to warm up. I mean I can go clear across town (15miles) before the gauge even moves from cold. I have had the thermostat replaced, and I know the radiator is good. Any ideas on why my engine isn't warming up? It only bugs me cuz of it affects the amount of heat I get!
