Is there any white/grey residue in your radiator ? if not, it doesn't need to be flushed. change transmission oil and filter every 30,000 miles under normal usage, belts should be inspected at least once a year, a tune-up every fall is also recommended

Can flushing my 4.3 engine with ATF fluid damage it?


If you add one quart to the engine crankcase, normally that will flush the system. If you completely fill the crankcase with 4 1/2 qts., that will wash the bearings and camshaft and will not have enough lubricating qualities. On the other hand, if the vehicle has very high mileage, sometimes flushing speeds up a problem that is just starting, but not evident.

05-07 Nissan Pathfinder hard shifting and bad coolant


These pathfinders have a major common problem and there is no technical service bulletin. Does your pathfinder have a hard (jerking)1-2 gear shift? does it have a hard shift in any other gears, when downshifting, or comming to a stop? Is your coolant a grey cooler or is your trans fluid bad? check your coolant on top of the radiator (when its cold) or in the coolant reservoir. Check your transmission fluid with the trans dip stick (with engine on). <br /> <br /> What is happening is the trans fluid cooler (on the bottom of the radiator) and radiator are cracking and trans fluid and coolant fluid are mixing together. If you catch this problem very very early it might be possible to fix it with a simple flush coolant and tanns flush and new radiator. But in most cases it requires a new transmission and new radiator and major flushing. It will probably happen to all pathfinders for these years, just depends on when. go to the dealership for check ups and check your coolant fluid, trans fluid, and shifting often to diag it quickly.

Bad radiator


Step_1 disconnect inlet (top hose) & outlet bottom) hose. I'm assuming you're replacing a corroded radiator. They now offer copper or plastic radiators that have high resistance to corrosion. If you replace with alluminum or steel radiator, do a flush job yearly with replace with the green radiiator solution or the red one if you replaced with aluminum radiator.
Step_2 disconnect the electric fan. first unhook the wire connection, then loosen the 4 screws that's holding the fan assembly against the radiator.
Step_3 Loosen the bolts holding the radiator unit. When re-attaching the new radiiator, install new hoses as well. Fill the radiator through the pressure relief cap with 60-40 radiator to water mixture. The instructions say 50-50, but 60-40 is a stronger solution that prevents freezing, boiling, & corrosion buildup. It there's a coolant filter, replace this unit as well. It looks like an oil filter cartridge.
Preventive miantainance: Perform a coolant flush every 50K miles. Most car manufacturers recommend 30K miles or 2 years, which ever comes first, but that's to boo$t revenue for car dealership service centers. IMO the max is 70K or 2 years. When you notice the temperature is overheating in the summer months, an engine radiator flush AND replacing the thermostat is the solution. Most shops will say "you need a new water pump" and the scammer had not even performed a diagnostic test. The water pump will last the life of the engine (140K+ miles) unless the car had run dry without radiator fluid. The radiator fluid lubricates the water pump. Running the engine dry (or low of) without radiator fluid damages the water pump. Running tap water instead of 50-50 or 40-60 radiator fluid mixture will also cause premature wear on the water pump because water by itself is insufficient lubricant on the water pump.

Radiator flush


Where are you located sherdibelle, is the cost labor and parts. See if you can find a radiator shop that will boil out your radiator. I quickly checked and a after market radiator cost $150.00-$200.00 so the place you went to is charging $800.00 labor or is this at a dealership. what is the labor rate.

Why does my car overheat when i stop.


check fluid levels in radiator, old radiator fluid flush system and replace fluid with new, bad radiator cap, bad thermostat, bad radiator hoses collapsing or you need to take your radiator to radiator shop or buy a new one. If you have electric fans make sure they are comming on when engine is at idle possible bad temp. switch on electrical fan.

Just purchased a 1998 cady sts with 94k miles, what milage does it need a maintenance?


Hi. the 100k mark will be a great mileage start point for some serious preventive maintenance on this vehicle. This includes a transmission flush, radiator flush,fuel and filter change and, complete tune up procedure.

I would also scan the ECM/PCM for any hidden stored codes as well.

Pleas rate and god bless:)

tire rotation, air filter, breather element,
Inspections:
Timing belt for wear and tear
other belts be it V-belts or Serpentine
radiator fluid (older than 3 years needs a flush and fill)
transmission fluid and filter change. if its a manual transmission then change the gear oil
Battery inspection
Ignition system--- Spark plug gaps,wires,cap and rotor and coil inspection.
Motor Mounts inspection
Other things good for a car of that high of mileage are flushing out the old brake fluid and filling with new....same for power steering.
mostly inspections
Last but not least... put a can of Seafoam* into your gas tank and drive it on the highway for at least 30-45 minutes. congrats on your high mileage honda :-]

You can purchase different fluids that will break down rust and corrosion, but if you have a very old or well worn (rusted) radiator it can cause leaks. I once worked on a 15 year old Ford Ranger where the person who had it before ran almost pure water in the radiator. The radiator ended up rusting out in the inside, and the cleaning fluids seemed to really help. It was odd, because the radiator appeared full, but when you went to drain it, only about a half a gallon would drain. It took me multiple applications of the fluids and flushing it about 6-8 times to get it cleared. This may be your problem.

First make sure your engine isn't hot. Typically, you just drain the old fluid in a pan and dispose of it properly. Don't let any sit on the ground or in an open container because animals will drink it.

I then simply place the drain plug back into the radiator, then pour about a mixture of anywhere from 30-50% antifreeze and the rest water. It is preferable that you use distilled water due to scaling.

In colder climates, it is more ideal to have a stronger ratio of anti-freeze verses water. Buy one of the cheap testing bulbs (they run under $2.00) to test your fluid.

Leave the top cap open, start your engine and let it reach operating temperature. When the thermostate opens (evidenced because your fluid levels at the top of the radiator will drop) you will then need to add more water to finish topping the fluid off just below the neck of the cap.

If you have a serious issue with rust, you could possibly look at having a garage flush the system for you. Some shops have the ability to flush the system under pressure. Usually they do only what I described above.
