Question about 1996 Nissan Quest

Nissan Quest 96 Engine running hot

My Nissan Quest 96 van is running hot because of a fan that has stopped to function. I realized that as long as the van is in motion, the engine doesn't overheat. But once I stop it at traffic lights for long during busy hours, it overheats. What are the posible causes of a fan not functioning. How can I solve this? By the way, I bought this fan with its housing about six months ago.

In the fuse/relay box under the hood in front of the battery are 3 fan relays. 1 for low speed, and 2 for high speed. 1 of high speed is back up. check the relays first.
B3 CHECK FUSES

  • Key OFF.
  • Check the 10A RELAYS fuse located in the interior fuse junction panel and the 65A RAD FAN fuse located in the main fuse junction panel. (engine compartment)
pLease rate as fixya if this helps. good luck

Hi again,

For some unknown reason(s), the Live Session was cut short. Our apologies for any inconvenience.

Perhaps you could try again? The old session/chat would no longer continue.

Cheers.

Check rad fan is operating. It should be coming on when temperature reaches normal operating temperature. Possibly fan shot or relay to fan is malfunctioning.

and since you already blown and replaced the gasket once, a repeat of the issue could mean a cracked or warp head or block... hopefully you didnt run the car very long when it overheated, then it is more likely just warped... that can sometimes be repaired by a good machinist. most importantly tho, DO NOT run the engine with that sludge in it. you will compound the problems. if you plan on fixing this yourself, remember your cooling system and oil need to be completely flushed.

You said something very important in your post. since you replaced the controls for the fan, have you checked to make sure the fan itself is good? You can easily test that by hot wiring it directly to the battery. If it fails to operate, replace it. Also check the outside of the radiator for obstructions such as bugs or leaves packed into the A/C condenser in front of the radiator or leaves stuck between the radiator and the condenser. If the radiator is internally blocked it is difficult to detect as most of the radiator is not accessible most shops use a heat sensing gun to check that.
If you decide to flush the system, flush the radiator separately from the engine as internal rust from the block will pack up in the radiator core and make the situation worse.
Another item to check is the clutch fan...It should not freewheel when the engine is hot.
The reason that it overheats in traffic is that in reality when at speed you don't need the fans...air flow caused by the speed of the vehicle is sufficient to keep everything cool. When in traffic you need fans to create that "wind" and any obstructions to the radiator become far more critical as Jeep radiators are borderline too small for the system in the first place.
Refrain from driving till you fix this as you can cause far worse problems (blown head gaskets) if it runs hot or overheats too many times.

SOURCE: overheating

well it can be a few things to check if you fan is working you can start the car and turn on the ac and if the fans come on you dont have an issue with those but if they dont come on you might have a bad relay or fuse.

I changed the thermostat and its still running hot.


Run it again. When it gets hot, check to see f the fans are coming on. Check fan fuses and relays. There are other things, but Nissan's are usually good about cooling the engine.

Try changing or switching out the distributor. Most likely getting hot and shuts down. Does it crank but no start whenever it stops? May only start when it cools down again.

Overheath


Also could be cooling fans. Did you notice if your fans are working when it is hot? Could be bad fan relay which would keep your fans from turning.

I would like to know the posible causes of engine running hot.


was the engine overheating before this repair? and again do u have bubbles in the coolant tank when the engine is running?, this is best checked when the engine is 1st started. I ask because I think u may have a leaking cylinder head gasket, this would account for the overheating still occurring.
