is it necessary to drain the coolant in order to change the spark plugs also what is the best step by step guide out there that is available as far as a service Manuel goes thanks.

Re: changing spark plugs ?
You do not have to, but draining at least a little will not make such a mess when you remove the intake with throttle.
It's pretty straight forward, remove the intake, coils, the plugs.
Removal and Installation
REMOVAL
1. Remove engine cover (1).
2. Drain engine coolant. CAUTION: Perform this step when engine is cold. NOTE: This step is unnecessary when putting plugs to water hoses (to electronic throttle control actuator)
1. Disconnect water hoses from electronic throttle control actuator.
2. Remove electronic throttle control actuator. CAUTION:
o Handle carefully to avoid any shock to electric throttle control actuator.
o Never disassemble.
3. Remove oil level gauge. CAUTION: Cover the oil level gauge guide openings to avoid entry of foreign materials.
4. Loosen and remove intake manifold (1) bolts (A) (B).
o =: Engine front
5. Loosen bolts in reverse order as shown. =: Engine front CAUTION: Cover engine openings to avoid entry of foreign materials.
6. Remove EVAP canister purge volume control solenoid valve from intake manifold, if necessary. CAUTION: Handle it carefully and avoid impacts.
7. Remove intake manifold.
INSTALLATION
1. Install intake manifold. NOTE: Be sure the intake manifold gasket is seated correctly in groove of intake manifold.
2. Tighten bolts in numerical order as shown. =: Engine front
3. Tighten intake manifold bolt (A). Then tighten intake manifold bolt (B). 1: Intake manifold =: Engine front
4. Install electronic throttle control actuator
5. Install water hoses (3), (5) to electronic throttle control actuator as shown. 1: Electric throttle control actuator 2: Clamp 4: Water outlet A: Paint Mark B: The clamp shall not interfere with the bulged section.
6. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION
* Check for leaks of engine coolant.
* Start and warm up the engine. Visually check for engine coolant leaks.

Re: changing spark plugs ?
Why are you changling them? I'm pretty sure the stock plugs are factory NGK Iridium.

Yah I'm wondering about that too? They're supposed to last hundreds of thousands of miles.kvg wrote:Why are you changling them? I'm pretty sure the stock plugs are factory NGK Iridium.

Re: changing spark plugs ?
U dont need to drain the coolant at all. I never have. Remove the engine cover. disasembale the air intake. There are 5 bolts holding the intake manifold to the block, one attached to an upper bracket on the passenger side and one to a bracket behind the throttle body. Its pretty simple I have already done it twice. U need a special socket thought to remove the spark plugs. its a 14 mm used for BMW, the sentra and the Versa. I payed 35 dollars for it from the snap on guy. Really came in handy the second time I did the plugs.
Re: changing spark plugs ?
My nissan versa has NGK platinum spark plugs from factory. The users manual recommends change the Platinum plugs at 25,000 miles. I replace the sparkplugs at 75,000 miles and found the NGK Platinum spark plugs. Be careful with this issue. Nissan versa in mexico has Platinum plugs, not Iridium.
