Hi there. Have you checked to see if the fans are coming on? Do they achieve both normal and high speed? Is there any noise or abnormal operation? There could also be an air pocket in the cooling system, or the thermostat installed backwards (it does happen). Does the engine boil over? Check the actual temperature of the engine with an infrared thermometer temperature gun and compare the readings to the combination meter gauge. The gauge or sensor could be inaccurate. I strongly suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several technicians available that can assist you with a car is overheating inspection.
How to Identify and Fix Common car Problems ?

When a water pump gets replaced, it`s not unusual to have some coolant leaking and for the weep hole to see some seepage. If the leak is small, it could just be from the seal`s break-in period.
When intake manifold gaskets become damaged, coolant may begin escaping from its system. Eventually even a relatively small leak will eventually cause coolant levels to drop to dangerous levels. Be sure to take note of any signs that your car may be experiencing a coolant leak.
The intake manifold also helps cool down the cylinders to prevent the engine from overheating. Coolant runs through the manifold to the cylinder heads where the coolant absorbs the heat and reduces engine temperature.
The water pump moves the coolant through the system and the thermostat regulates this flow to maintain operating temperature. If the water pump has failed, the coolant will not flow through the system so the temperature will rise quickly and the heat will be concentrated on the engine.
Pump impellers and seals may fail and foreign matter and debris from the tank can clog the pump internals. Low water levels in the tank can also cause run dry failure. If your pump/motor system stops running you may have an electrical fault or foreign matter seizure.
If the intake manifold gaskets leak coolant into the intake manifold the engine may overheat as a result, without any visible external leaks. Any coolant leaks should be addressed as soon as possible to prevent the possibility of serious engine damage occurring due to a bad intake manifold gasket.
Water pumps can leak from 2 different places; the shaft seal or the water pump gasket. If the water pump bearings are starting to wear out they will allow the shaft to wobble and coolant will leak out.
After the water pump is repaired, the coolant may still leak for a variety of reasons. First, the seals around the water pump may be damaged. These seals prevent coolant from leaking out, so if they are damaged, coolant can easily escape. Second, the gasket that sits between the water pump and the engine may be faulty.
Without a correctly running water pump, your engine will overheat in the summer or freeze in the winter. This can not only cause damage to the gaskets, cylinder heads and pistons, it often results in total engine failure.
To ensure these technologies work in the way they were designed to, these intake manifold gaskets must be installed on a clean, dry surface with no additional sealants used.
If the ECM reads low intake manifold pressure due to issues like a vacuum leak, it`ll assume that the engine load is high and send more fuel to compensate. This leads to excessive fuel consumption and poor fuel economy.
Irregular Operating Temperatures One of the most prevalent symptoms of thermostat failure is irregular operating temperatures. A stuck closed thermostat will cause engine temperatures to skyrocket, while a stuck open thermostat will cause an engine to run cool.
Strange Sounds And Temperature Changes
You may hear rumbling, boiling, or knocking coming from the radiator. All these signs point to an issue with your car`s cooling system. The thermostat also affects the temperature of air that flows in your vehicle through the vents.
Common problems include overheating, leakage, low water pressure, noisy operation, and cavitation. These problems can be prevented or fixed by regular maintenance, inspection, and replacement of worn-out parts.
Sealing Intake Manifold Gaskets. There are a couple of different sealers we like to use when doing this kind of work. To hold the intake gaskets in place on the head, we like Edelbrock`s Gasgacinch, which is a simple contact adhesive. For RTV, we like the Permatex Ultra Gray or Optimum Gray.
Generally a really bad intake manifold gasket will make a car run rough at idle and/or cause a service engine light to illuminate. … As far as driving the car, as long as you don`t have a fluid leak or the car is not stalling or running rough, it should be fine to drive for a few months.
The exhaust valves can get burned, the leak can damage oxygen sensors, or the problem can cause the catalytic converter to fail prematurely. It may also increase your fuel consumption, meaning you spend more on gas each week. This is a job best left to the pros since a leaking exhaust manifold can be dangerous.
Typically, a vacuum leak will cause situations like hard starting, rough idle, excessive fuel consumption, and engine codes. You might even be able to hear a leak – sometimes a whooshing or whistling sound can be heard with the engine running.
What sound does a bad water pump make? Any high-pitched sound, or an increasingly loud whining sound as you accelerate is usually coming from the car water pump. The same sound happens when a belt is loose, or the bearings are bad. No matter which of these it is, getting your car to the mechanic is a must.
Squealing noise
A squealing or chirping noise from the front of the engine can also be an indication of a failing water pump. It can sound very much like when a serpentine belt is making noise, and in many cases, that`s because it is.
Antifreeze (aka coolant) is pumped through your vehicle`s engine as you drive, absorbing excess heat and exchanging it with the outside air. That means an antifreeze leak could cause the engine to overheat — and that can lead to major engine damage.
The water pump is one of the vehicle components that may never require replacement if your vehicle is well-taken care of. You can own a car for over 15 years and never have to replace the water pump. That`s not to say that it can`t develop a problem.
The three symptoms this might cause are: Poor engine performance. Poor fuel efficiency. Sudden engine surges.
Manifold Pressure Gauge:
If RPM is reduced before manifold pressure, manifold pressure will automatically increase, possibly exceeding the manufacturer`s tolerances. When power settings are being increased, reverse the order-increase RPM first, then manifold pressure.
