Timing Belt Replacement On Rb25det

[mattymagoo22]

So you've bought yourself a skyline (R33 GTS-T) and you've no idea how many kilometers its got on it, its genarally a good idea to change the timing belt as if it snaps worst case scenario new engine!!!

First off this job probably take 1.5 - 2 hours depending on your skill level (add another 2 hours if you are changing water pump cam and crank seals).

What you need:

Tools- socket set, 8 10 12 14 mm spanners, 27mm socket and breaker bar, palm sized mirror (mums will do) allen/hex keys, screw drivers, some sand paper and a razor blade (cleaning gasket surfaces), a lead light and a hammer.

Parts- I used genuine belt as aftermarket one I tried was noisy( tension was fine) crank seal has to be a genuine no aftermarket listing cam seals and waterpump I went aftermarket.

Timing belt- #13028 5L327

Crank seal- #13510 10Y10

Cam seals- #G00084 non gen

Be careful with the water pump as one of the bolt holes (10mm) on the top may not line up if its the wrong pump.

Coolant- whatever tickles your fancy (some might recommend gen stuff).

Lube- Vasoline, carby cleaner, GP grease.

Okay lets get started.

1. Start by listening around the timing belt area to how the engine sounds give it a few revs and take note of certain noises. Jack to car up onto stands so you can get to the under carrage. Remove splash gaurd to gain access to A/C belt tesioner (and coolant drain if changing waterpump its on the passenger side of the radiator large phillips).

2. Start by loosening the 4 10mm nuts that hold the fan to the waterpump pulley then loosen the alternator belt off (adjustment 12mm on drivers side off motor) then you can completely remove the fan (it may take some prying I tapped between it and the waterpump pulley turning it each time and it will come away).

he did say "save yourself some dosh". you'll save yourself around $2 of labour for removing those 4x10mm bolts and listening for noises.

hey all

not sure if i am posting in the right section, but i just need some advice.

i just got the timing belt and all the other anxillary belts changed. the belts are new, so the mechanic decided to tension the belts a little abit more.

my question is: is it ok to tension all the belts a bit more? would that cause any adverse effects?

and also after the timing belt has changed is there any 'rules of thumb' like you should drive it easy for the next 100km or can you just drive how you normally do?? i ask this because i know with clutches and brakes theres that "bedding" in stage. i was just wondering do i have do the same with the timing belt.

i'm just after some advice,

hopefully someone can help, cheers in advance

Kind regards,
