1988 Ford Ranger Fuel Pump Over Heating And Stops Running. It Cools Down And Runs Fine Until Heats

What happens when you overfill the radiator reservoir tank?

Not much will happen in most cars. As the liquid heats it will expand & run out the overflow tube. This might happen a few times but sooner or later it will get down to the proper level.Keep an eye on the coolant level that too much doesn't overflow out. If it gets low when the engine is cool add a wee bit to bring it to the proper level.And remember: be sure to read the instructions carefully … some 'antifreeze' is premixed, while some brands come full strength. The unmixed coolant doesn't absorb & transfer heat as well as properly mixed coolant. If your coolant is full strength mix water with the coolant in the amount shown on the jug's instructions panel. If already pre-mixed don't dilute further.Finally, if you're putting new coolant in the cooling system don't forget to open the heater control to fully open when you drain the old coolant, then leave it open when adding the new coolant.. The heater core inside the cabin is like a second radiator … heated coolant flows from the engine to the heater core & transfers heat from the coolant into the cabin. Failing to open the heater control can cause air to enter the cooling system which can result in engine overheating, possibly causing a blown head gasket or even a cracked block or head.

What happens if you attempt to drive with a broken serpentine belt?

The serpentine belt powers many different accessories and required pieces of equipment on an engine. You can live without the air conditioner. The car is usable for a short time without the alternator working if you have a good battery. You can man handle the steering wheel without power steering. Some cars have a smog/emissions control pump that needs to work or the engine will run rough or even not at all.BUT, you will overheat your engine if the water pump is not turning and pumping coolant through the engine and radiator. You could make a short drive of 5 minutes or so before engine heat would be a problem. Hopefully, that is to a mechanic who will replace the broken serpentine belt.

Why does my car's temperature get high when I turn the AC on?

Assuming that the auxiliary fan (s) come on when the A/C is on, There are several reasons that the temp gauge rises….Is your temp gauge accurate? Most car companies have the dash gauge designed to go to the middle of it’s sweep and stay there, unless the engine gets really hot, they usually just goes to the middle and sits there, as long as the coolant temperature is between 70 C and 100C. They make them like that so that the consumer doesn’t see it moving around on a regular basis, that way, when it does go up, it gets noticed quicker. To determine if yours is accurate, or if it’s the kind that just sits there until something goes really wrong, an OBD2 code reader talks to the temp sensor that the engine’s ECU ( Engine Control Unit )… If the reader shows the temperature rising, but the dash gauge doesn’t budge.. then you know..Let’s assume that your gauge IS accurate… When you turn on the A/C , several factors now come into play. First, you’ve just placed a ( slightly) higher load on the engine, which is now burning more fuel, and creating a bit more heat. Secondly, that fan that just started spinning? Yup, it’s electrically powered, which means the Alternator is now needing more power from the engine.. A bit more fuel, a bit more heat created for the engine’s cooling system. Thirdly, all that energy ( Heat ), that the A/C has removed from the car’s interior .. Guess where it’s going?.. To it’s own little radiator, properly called a condenser coil, and that’s located right in front of the radiator. So now you have hotter air than before passing through the car’s radiator.Thermostats don’t “pop” open and closed, they open a bit as the coolant temperature gets to the design spec of the cooling system. They don’t open to full flow for at least another 10 C.Thermal efficiency.. As a radiator gets older, scale buildup on the inside of the tubes inhibits the transfer of heat to the air passing over the fins.Add all these together, and you have the reason that the temp gauge moves when you turn on the A/C..

What could be the cause of a car’s temperature gauge to fluctuate?

There are several possibilities.1) faulty teperature gauge. In this case the gauage will have to be replaced. This is relarively simple and inexpensive depinding on the make and model of the car.2) Issue with the radiator, coolant of the car. This could be caused due to insufficient coolant, leakage of coolant, damage to the radiator of the car. This will require extensive repair. In this case, it is advised to get the issue diagnosed and fixed at the earliest to avoid engine damage due to over heating.Hope this helps. :)

Is it okay to drive your car without thermostats?

If you take out the thermostat then the coolant will just flow 100% by the water pump. Assuming that your system is properly sized so that cutting off flow with the thermostat will result in the proper operating temperature being met then running without a thermostat will always result in a lower than intended operating temperature.Here are some things that will happen:Your engine will run cooler than the desired temperature most all of the time andit will pollute more since it is tuned to run at the designed temperatureYour heater will take longer to become effective since the coolant is used to warm the heater core heat exchanger so you may, on cold days take longer to warm the cabin andmore importantly, it will take much longer to defrost the windshield using the defroster function.Probably it won’t hurt short term to the car engine itself, I don’t think. But in the long term operating it significantly below the designed temperature could have a number of effects, perhaps on lube viscosity, various carbon buildups that lead to other engine performance problems and possibly permanent damage.I once had a mechanic shop replace the thermostat and flush the coolant. When I get it back the car took forever to warm up the heater and get the engine to the temperature. I eventually took off the thermostat housing and found he had placed it about half way off and clamped it down with the housing out of position- it didn’t leak but the gap on one side pretty much made it free flowing.

Can I drive my car with a broken thermostat?

Yes of course you can! And, you may be surprised by just how far you manage to go, before the engine overheats, seizes, and turns into an immovable, useless, expensive to replace, chunk of metal!It’s probably easier to remove the plates, pour gas all over the inside, and light a match—the effect is about the same. Thermostats invariably fail in the “closed” position so the “shelf life” of a car with a bad thermostat is measured in minutes.You need to borrow a car and go buy another thermostat and gasket—-or at least the gasket. Typically, the cover is held on with two bolts, so use a wrench (or pay a mechanic) to remove the bolts, and then the old thermostat. If you haven’t been able to afford a NEW thermostat, use the new gasket to re-install the cover, and don’t drive too far, especially in winter, til you actually get a new thermostat.

What is the cause of white smoke from the exhaust and fuel smell?

White smoke and the smell of raw gas out the exhaust. Is a definite sign of running rich.Condensation well mostly disappear. Along with not having the smell of gas vapors. Once the engine reaches operating temp.Are there any check engine lights displaying. From the ECU/PMC throwing a error code. Causing the engine to run limp mode?When was the last time the fuel pressure was checked? Too much will extra gas, pass through the injectors. Much like changing the Injector Pulse Width MAP.A hanging injector will mostly likely cause cylinder(s) to fill with gas. Depending on what intake valves are open, along with intake manifold. The fuel system stays pressurized, even tho fuel pump is shut off. Allowing the pressure to bleed off through the injector(s). By keeping the system under pressure. Allows for quicker starts. Because there is no lag, while the fuel pump rebuilds the lost pressure.Running that rich can/will cause the oil film. On the cylinder walls, getting washed off leading to scuffing.I could see the white smoke, smell the gas. When adjusting fuel pressure on my super charged CRX Sir, may it R.I.P....
