Commute/Temp discussion

My wife's commute is 8 miles each way. 3 miles are through neighborhood type driving, the other 5 are at 55 mph with a couple stop lights thrown in. She tells me by the time she gets to work, the Ex is fully up to temp. But that's right when she gets there, and we are talking Houston heat with full AC use. As the temps are coming down, she is telling me it is barely reaching temp (190* ECT/EOT) and sometimes doesn't even make it there.

Would it be worthwhile to block some of the radiator off? I was thinking about maybe blocking half the radiator off, that case if we do have a warm day, or a ling drive I won't have to fudge with it.

Thoughts, opinions?

I think thats ok. I wouldnt suggest blocking the radiator. The best way to check is to get it up on the interstate, if it gets up to op, and there isint a wide swing in temps, your good. Of course you should check your temp sensor before you start up and see if it is close to ambient in the morning.

Sent from my phone that somebody didn't help me get.

I think what the op is getting at is driving the truck daily but not spending much time driving AT operating temp. There's been a lot of discussion about the truck not being at temp long enough to take any moisture out of the oil as well as creating increased wear.

I have a short commute as well. It's fine in the summer but this time of year when ambient temps are around 40* I can drive into town and back and still not see operating temps. When the daytime temps get up around 60 a blocked grill will send the temps too high so I'm waiting till the temps stay cool throughout the day. With the whole grill blocked (I block the rad behind the grill) the truck will warm up in the driveway for 5 or 10 minutes before we leave and be at temp by the time we're in town at -10 or so if I remember correctly. Once it hits -40 that's a different story. Everything takes a long time to warm up at those temps IF they ever warm up!

I say block it and watch the temps, you'll learn how much you need to block off to get warmed up quick but not overheat. The quicker you're at operating temp and the longer you stay there the better. JMO

Does anyone really care what I used to send this?

it wont get to temp in 8 miles of city driving. Blocking the radiator is fine.

I block mine every year once its starts hitting highs of 20 degrees or so
