Smoking Engine Block

I have a 1999 Chevy Silverado 1500, single cab with a 4.8L V8 engine with about 225,000 miles on it. I have a antifreeze/coolant leak and have been having to put a whole new jug of antifreeze/coolant in my truck every day for the past 6 days now. I just found the leak right underneath the engine block, just in front of the oil pan. It was a pretty steady stream but now my engine block has started smoking. My question is this. Is my truck done for and should I just buy a new car or can I just replace the needed parts and save it? I want to try to avoid buying a new car for now but I feel my trucks days are numbered.

Sounds like your water pump is taking a leak on you. Personally, as long as the coolant isn't getting into your oil I'd repair the problem and keep driving it. Water pump aren't too expensive and from what I've been told/researched not a real hard job to do. Big thing is to make sure the water pump gaskets seal up real good.

If you can get a mirror or look from below, look for a small hole on the water pump on the bottom of the pulley snout. There should be a drain hole between the front bearing and the rear bearing of the water pump. When you see water coming out of this hole, that means the rear seal on the bearing is letting water past it. What happens is the bearing gets worn out and it leads to the seal getting worn out.

 

GM sells a kit consisting of the pump and gasket. I think they also have one that has the thermostat housing, gasket and thermostat. Do yourself a favor, change both as well as the hoses. No sense changing a water pump and using old hoses and belts. Also, consider changing the belt and idler pulleys on the serpentine belt. Those bearings wear out too. Trust me.

 

The whole job shouldn't take you more than a few hours if you've never done it before. Less if you have experience.

You could have been taken to the cleaners if you had gone directly to a shopping or dealership.

 

You might want to learn about some of the basics, at least.

      The Peckish Synapse

      By Grumpy Bear · Posted

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
