Where is the coolant leaking from behind the engine?
Seems to be in the area between the 2 spark plugs on the drivers side. Seems to be an external leak because no coolant in oil, and no check engine light. I had been noticing coolant lowering every week or so, but not much. Now after this trip, the leak is much more pronounced.
What happens when you have a vacuum leak in your engine?
Engine vacuum leaks are commonly associated with the following symptoms, but keep in mind that this is not an exhaustive list. An engine with a vacuum leak could potentially run normally, but it may idle faster than usual, idle roughly, misfire, hesitate, or stall. You may find your vehicle doesn’t accelerate as well as it typically does.
How can I find a vacuum leak in my car?
Start with a vacuum hose diagram, which you can find in a repair manual or sometimes on a sticker under the hood. Using one of the following methods, finding the vacuum leak might manifest itself as a change in engine speed or idle smoothness. Smaller leaks may only manifest themselves as fluctuating STFT readings on a scan tool.
What happens if you have an intake leak in your car?
Major intake leaks might prevent the engine from starting at all. Fuel Economy and Emissions The lean air-fuel ratio will burn hotter and increase the generation of oxide emissions, such as nitrogen oxide (NOx) and sulfur oxide (SOx). Even if the check engine light isn’t triggered, the vehicle may still fail emissions testing.

Where does the oil leak come from in a PowerStroke?
Top of engine oil leaks can also come from the two plugs installed near the rear of the engine — into the head.These two cylinder head plugs face into the engine valley and are oil drain ports. They’re located just below the valve covers. If one of the plugs comes loose or the o-ring fails, it can leak a lot of oil into the valley.
What causes a diesel engine to leak oil?
Leaking diesel that runs through the engine valley and down the back of the motor. On the way, that fuel collects dirt and oil from the valley. Then it runs out the valley drain hole and down the rear of the engine, making it appear to be an oil leak.
What to do about oil leak in Riffraff diesel?
Look to this location after you’ve inspected the oil discharge hose fittings, the rear plug and/or the “non-serviceable” plug. The rear plate requires an 8″ pair of c-clamp pliers to remove the retaining c-ring. Riffraff Diesel sells a replacement rear plate o-ring seal.
When did the Toyota long life Red coolant come out?
But, your vehicle (not sure what year but somewhere between 2000 & 2004, right?) would most likely have had the Toyota Long Life Red coolant in it. Is your current coolant red in color? This coolant is meant to be changed every 30,000 miles or 3 years, whichever comes first.
Is there water in the oil or coolant tank?
There is no water in the oil, and there is none coming out the tail pipe. Not sure what is back there that could leak coolant. Just started doing this as I haven’t noticed much besides the coolant tank needing a bit more coolant after a week or so.
Why does coolant leak so slow in a Toyota Tacoma?
The reason it leaks so slow is as the engine gets hot, the metal expands (thermal expansion) and makes a seal, so no leak while the engine is running at normal operating temp. As the metal cools it shrinks but the coolant is still hot and under pressure. Once the coolant cools, the leak stops again, so you have to look in that specific window.
Where to look for coolant leak in Toyota 4Runner?
Look for coolant trails because sometimes it can be leaking out of the water pump or thermostat and the wind will blow it back towards the steering rack. A small extendable mirror and a flashlight will help find the source.
Can a worn radiator cap cause coolant to leak?
A worn, weak, or leaking radiator cap will not hold pressure, lowering the boiling point and allowing coolant to boil out. It may also allow coolant to leak externally. Luckily, this is a quick and cheap fix. Just wait for the engine to cool, refill the cooling system, and install a new radiator cap.
