Why does my car take awhile to warm up?
Your heater core can fail, and signs that it’s doing so include no heat, excessive window fog, coolant leaks under the dashboard, low coolant, your vehicle overheats, and you smell coolant inside the vehicle cabin. If your heater won’t heat up, your heater core may be the culprit.
How long should car engine warm up?
Let the engine run for 30 seconds. That’s all it takes in most vehicles that are 30 years old or newer. If it’s extremely cold and your vehicle is covered in snow or ice give it a minute or two longer to warm up.

Why is my boat hard to start after warm up?
My theory is a leaky carb float valve (is that a carb or injection motor?) or maybe primer valve, just slightly flooding the engine. At home on the muffs, engine is much easier to start without backpressure on the exhaust. On the water, lifting the hi-idle lever advances the timing, let’s it start right up.
What causes an engine to die in hot weather?
Sometimes the condenser inside the distributor or the one by the coil, if equipped, will cause this. Even less often, the ignition coil itself. Both of these are fairly rare. Check the car for spark when it dies and won’t start, then go from there. 1976 L48 RoadDemon carb, Weiand intake, 3:36 gears, DUALS.
