Just A Observation Of My Engine

On my truck that I just recently bought I looked around on the engine and noticed something a little odd. On the right side of the engine compartment there looks like there is a shut off valve to something, its on one of the hoses that run into the firewall. I don't have a digital camera, so I can't take any pictures, but is this normal? On the previous trucks I owned, I have never seen this before.

Sounds like a flush adapter for the coolant has been installed in one of the heater hoses.

+1 but it's hard to say for sure without seeing it. Try to borrow a camera or something.

Some old school guys used to put shutoff valves in the heater hose to keep hot water from circulating in the summer... wonder if it could be that? Not sure what kind or year of truck we are talking about?

Its on a 01 silverado with the 5.3. There are two hoses that go into the firewall and they both go into the engine, this valve is on one of these hoses. And it also looks like plastic.

Those should be heater hoses (assuming you are not looking at the A/C lines). The plastic item is likely a hose port installed for flushing the the coolant system or a valve to limit/stop water flow to the heater core (colder A/C). Does your heater control valve work correctly? Maybe an ethnic fix for a failing temp controller.

I have looked again, and its on the hose that runs down into the front part of the engine, and I found the receipt where the previous owner had the radiater flushed. The radiator shop installed the t-fitting. So will that hurt anything?

      GM Hard Folding Tonneau by REV review

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
