I am looking for some rough figures on the normal time fo an EF7 CRX with D16ZC to start registering a rise on the temp needle, and for it to reach operating temp just below half?

Thanks

 

Obviously this all changes depending on climate, idling time, drive time, load, heater on/off... ect....

Summer in Midwest - 2-5 minutes
Winter in Midwest - 3-8 minutes

These are generic time frames as I don't use a stop-watch or watch the clock to verify... The low end is more "out of the gate" style driving; the high end being idling time.

 

I would say in anytime it's +70F it should take less than 5mins to warm up (ideling or driving)
If it's under 30F.... it'll take a while...if it's just ideling ... 15mins... if your driving it right away no more than 10mins for sure.
