Warm up time?

I have a '74 914 2.0L. Let's say the air temp. is about 50 degrees. Let's also say that the engine is stock and all pieces of engine tin and thermostat are present and working. How long does it take for y 'alls' engines to get to normal operating temp? Mine seems to take a long time (about 10-12 mins. worth of city driving). Just curious.

I reinstalled my heating system for the upcoming cold weather this past weekend. As I was laying under the car, a thought crossed my mind: "What was Dr. Porsche thinking?"

Thanks again PP for this website!

I'm not sure what you mean by "normal temp"? If it is hot enough to get plenty of heat for the heater/defroster, then it should not take long at all. Our stock 74 2.0l puts out hot air with in 3 to 4 blocks of driving. I would make sure you are feeding both sides and that there is good solid connections in all the tubes and ducts. I tested ours with a biiig shop vac set to blow into the duct at the hot air fan connection and found lots of cracks and tears in all the flexible lines, but you couldn't readily see them. I replace them yearly to prevent this from happening again.

I agree with Brian. With all the hoses in good working order, What my 1.7 lacked in HP It made up in comfort level with the heating system. As I recall, The first time I drove my car I remember being relived.

Guys, thanks for your input. I only wanted to know how long it takes for your engines to reach normal operating temp. I gather that 10-12 min. is not an unusual length of time. I aplologize for offending y'all with my comment questioning the layout of the heating ducts. For this I am truly sorry. Dr. Porsche has cursed me for this comment. I suddenly have a slight "miss" now.

Thanks,
