I have a question about the 1998 Silverado 4x4 vortec 350 automatic that I just bought. That's making me question if it's the water pump. Computer, fuel pump and many electrial connection to say the least, are different. It's kind of hard to tell what color it is because it's so low. That will be the block drain plug. If the plug is out or damaged it could cause the water to leak out of the back of the engine.
If you put in a thermostat that opens sooner it will allow a cooler engine. Engine coolant circulates through your engine to keep it cool in the summer but won't freeze in the winter. Some like to run their car cooler, but in my opinion if it warms up to a slightly higher temp 200-210 I feel better about moisture being vaporized from the crankcase. Allow the truck to run with the pressure cap tightened on the radiator. You can sometimes prove this is the problem by removing and checking the spark plugs.
. Mine was leaking and, as bad as it sounds, is glued to prevent any further leakage, which has worked well so far. I just need to put some antifreeze in it for now until it's done at the shop getting the transmission fixed. The vehicle was immediately taken to the closest dealer where the coolant was flushed and replaced. This is not a wear and tear problem. Always wear safety goggles when working on your Silverado 1500. Empty the radiator into a drain pan, remove and inspect the upper hose I think the upper goes to the water pump, but I'm not sure.
If gm is aware of this problem caused by the mis-manufacturing of the part a recall should be issued to all affected vehicles. Then check the radiator, drain plugs, radiator unit, etc. My Owner's Manual says the coolant heater will be wrapped up and located near the power steering pump. Be sure to check your owners manual to determine the correct type of fluid to add - for Chevrolets, it will typically be in a section titled Fluid Capacities in the back of your manual. A used head is usually cheaper than rebuilding existing and it is probably warped, meaning it must be milled which will alter compression on that side and can screw up valve train geometry.
If you notice an oily surface in your coolant, immediately have your mechanic inspect your Silverado 1500 for head gasket leakage. Some 1996 and ups developed some serious cooling sytem issues. This caused dissimilar metal corrosion in the fitting itself which lead to unnoticed pin hole leaks in the cooling system. It would probably be less expensive to buy the correct engine or replace the truck. If you are asking for now or temporary go ahead and color match it.
Be careful the engine and water will be hot. It is common for them to leak too. Sounds like it may have overheated sometime in the past. You will also have 1 or more cylinders with low compression so it will misfire blow white smoke out the tailpipe since it is gettin … g into cylinders and may even hydrolock depending on volume, meaning engine could seize suddenly while on the freeway possibly destroying trans and or driveshaft as well. There was no testing required for this, it was replaced due to age, mileage, and because I was in the middle of replacing various cooling system components. Turning on the heater will make the temperature gauge drop; then you will know that your thermostat is freezing and not allowing the coolant to circulate. I have seen many problems with the Intake gasket on these models as they are supposed to be reusable.
If I remember correctly, the leak was caused by a galvanic reaction between the 2 different metal components. If it's leaking then coolant will be running down the lower radiator hose. The most common cause is the intake manifold gasket. The vehicle was taken to an independent mechanic where it was diagnosed that the cylinder head was leaking coolant and needed to be replaced. When running, the truck has some white vapor in the exhaust. You're either spewing it out or your burning it. If you notice an oily surface in your coolant, immediately have your mechanic inspect your Silverado 1500 for head gasket leakage.
For now to be safe run the stuff that can go with any color. Happy hunting owe also this will let you know if you pulled a me and over flow the coolant through the reservoir overflow and then wonder why there was coolant everywhere. Could be a freeze plug too. Watch the gauge as it is running; when it is overheating, turn on the heater. Can anyone tell me if the pump was going bad would the truck run a little hot? Sometimes, if the leak is bad enough, soon after starting the engine you can smell ethelyn glycol coolant at the end of the tail pipe. Chevrolet is apparently aware of this common problem and has issued I believe service document 1986750.
Aluminum blocks can be repaired and welded the same as cast iron the difficulty is in the material being welded and where the crack is. A stuck open thermostat will have an engine take forever to warm up as coolant … is constantly flowing from the start and a stuck closed thermostat will make your engine run really hot and possibly blow it. I don't know if you can buy the gaskets or not but with the mileage on it the water pump is on borrowed time anyway. Promptly wipe up any spilled fluid as it is highly toxic. When I pulled into my drive the temp finally went down, almost like my thermostat just opened up.
I have a 1998 Silverado 1500 that has been experiencing some overheating problems. What's a good antifreeze to put in it for now? The cardboard will also help direct you if it makes it past the fan. The contact stated that general motors wasaware of this problem. Does anyone have any links on how to change the water pump on a 95 silverado? It's difficult to know if the sensor is broken just from normal operation of the vehicle; to find out, you have to test the sensor itself. To make it cooler step 1 is to change the thermostat, assuming everything is working correctly a cooler running thermostat. It will have a black rubber hose hooked to it.
