Major Service + Extras - Self Imposed...

[kendog]

Hi All,

A few weeks ago when I had the golf up on the hoist to replace front rotors, we noticed a drop of green coolant that seemed to be directly under the water pump area. So, thinking it's best to nip it in the bud, I am replacing the water pump, timing belt, and the rocker cover gasket, which is also now leaking a bit more. I'm doing it this Saturday (my good mate the qualified mechanic is), and I was wondering if there was any info/advice out there on anything I need to look out for, or any parts I'd missed?? I will have alreday bought about $500 worth of parts by Sat, so not keen to spend too much more as I may sell to get a gti down the line.

Here's the car stats and the parts list, feel free to add any constructive input! :

Car:
2000 MK4 Golf 1.6L, 5sp Man, 135000 kms, Engine: AKL, Anything else???


Parts - Already Bought:

VRS Kit - Basically a head/rocker cover gasket kit, where I'll replace the rocker cover gasket and all other inlet/outlet gaskets along the way, using all/most except the head gasket.

Timing Belt Kit - Timing Belt, Timing Belt Tensioner, 2 seals,

Water Pump - Plastic impellar, I asked for metal, but plastic turned up, can refund if I want.

Thermostat - plus o-ring/gasket.


Parts - To Buy:

Oil - Looking at Mobil 1 ESP 5W30, avail at GLLubrication, 5L = $65, +post = $80.

Oil Filter - no idea, suggestions?

Coolant - old is green, so looking for G12++ or whatever it's called, will have to flush old,

Anything else?

Notes - I'm not sure if this oil is for a more 'perfect' engine, and I might need something thicker? or is this high end oil providing the protection I need. I guess I'm just worried about the oil being too thin on a car that is already pumping out oil up through the rocker cover gasket.

Was thinking of doing an oil flush, but don't know much about it.

[Umai Naa!!]

The oil filter is pretty common, and you can get them from pretty much anywhere. Dealers usually charge no more than $20.

As for the oil itself, 5W30 is probably a little thin. A good 10W30 might be a better option.

G12++ pink coolant is idea, as you know it's correct for the car. As you said, it's ideal to do a full flush of the green stuff.

An oil flush can't hurt. You can buy a bottle of commercially-available stuff, or even half a litre of diesel fuel in th existing oil will do a similar job.

[JustCruisn]

Don't use that green glycol coolant, it is probably why your water pump failed. Use only G12++. Get all the green stuff out as they don't mix too well.

Don't put in a plastic water pump, go back and get the metal one. Plastic will break and the car will overheat.

Thanks guys,

Yeah, the green coolant is from the old owner. I'm def getting rid of that and flushing it, then getting 2 x 1.5L bottles of G12++ from probably HSY to mix 50/50 with 3L of (distilled) water to make a total of 6L, 1L left for top-ups.

Water Pump: They (ASV) were certain that it was metal, and didn't know that their supplier had changed from metal to plastic within the last shipment. They even went & checked several boxes in dis-belief. They don't have other metal impellar ones, so I'd have to get a refund, or swap for coolant, oil filter etc, etc,. Or just get the refund & get the water pump, coolant, etc, from HSY around the corner from me, they're a bit cheaper as well. I'll ring to check their water pump is metal impellar.

JC - your thoughts on the oil? should I go with the VW recomended "Mobil 1 ESP 5W30" ? Or is that for 'newer' cars? should I get something thicker? That could end up cheaper too, but I'd prefer to spend a little if I get the right oil over a cheaper option in this case.

I think I might do the oil flush if I can find out more info, looks a little gunky in there.

Any more people out there with thoughts on the oil?

2000 golf 1.6L (AKL) with 135000 kms?
Also, it will probably be going in after an oil flush. Rings are most prob original too.

How much oil do I need?

[Umai Naa!!]

You'll only need a 5L bottle of engine oil. You'll usually have .5-.7L leftover for top-ups.

The water pump you should be able to get through HSY. As for metal Vs plastic, it's up to you in the end. There's good and bad sides to both.

[h100vw]

I don't think its a big deal plastic V metal. They last 10 years and you would be a fool not to change it with every belt change. Also mentioned getting a GTI so unless you are going to sell it to someone in the family, no guilt to worry about. I have a plastic one in my A4, never keeps me awake and the one that broke was plastic.

Hey mate, not sure if you mentioned it above but have a geez at your fuel filter. Pretty sure they last ages especially if you're using good clean fuel. I did mine last service the filter only cost me $37 and installing it was really a piece of cake for me with no mechanical experience.

[kendog]

Just ordered from HSY, I should've gone to these guys before, they're cheaper AND right near my work.

Ordered from HSY:
WATER PUMP - Metal Impeller and about $10 cheaper!

COOLANT: G12 or G12++, he wasn't sure.

OIL FILTER: Standard.

Still have to find OIL. I REALLY need advice on that!

Thanks, I might just do that!

Any input on the oil?

Bump!
Which oil for a 2000 golf 1.6?

BUMPITTY BUMP!!

I have to buy this oil tomorrow morning, NO-ONE out there can recommend an oil?? C'mon guys!!

[Diesel_vert]

For your car, any oil must have at least one of these specs on the label:

VW 502.00 or VW 504.00

For viscosity grade, stick with 5W-30 or 5W-40.


But I think you might be better off with a 5W-40 oil, given the car's age.

Awesome! thanks for the reply mate!

I will definitely look for the VW certification numbers, but just wondering about the grade...
I looked up the Mobil 1 site (def not only looking for mobil), and it suggested the oil for my car is: Mobil 1 0W40.

What is the difference between 5W40 and 0W40 ? There's also a 'High Mileage' Mobil oil that's 10W40, so what's the diff?

Mobil site: https://www.mobiloil.com/usa-english....aspx?option=1

It looks like with the time constraints, I'll have to get either mobil oil from GL Lubricants, or other brands from 'standard' places like: repco, supercheap, autobarn, etc.. Unless there is somewhere better on a Sat Morn?

Again, BIG thanks!

Basically, you need to use an oil with a HTHS of more than 3.5, otherwise it'll be too thin for your engine. Hence, VW 502 and 504 prevents you from using oils that are too thin, irrespective of viscosity (that's really the only reason why I said to use 502 or 504 oils).

All ACEA A1/B1/A5/B5 oils have a HTHS of <3.5 (which rules them out) and all ACEA A3/B3/B4 oils have a HTHS >3.5 (which VW 502 and 504 is based on).

Viscosity rating itself is not a sufficient indicator. For example, M1 5W-30 ESP has a HTHS>3.5 (acceptable), but M1 5W-30 has a HTHS<3.5 (unacceptable).

I looked up the Mobil 1 site (def not only looking for mobil), and it suggested the oil for my car is: Mobil 1 0W40.

What is the difference between 5W40 and 0W40 ? There's also a 'High Mileage' Mobil oil that's 10W40, so what's the diff?

The first number indicates how well it flows when the engine is cold (lower numbers flow better and vice versa).

The second number indicates the viscosity at operating temps (lower numbers are thinner, and vice versa).

A 0W-40, 5W-40 and 10W-40 will roughly have the same viscosity at operating temps, but the 0W-40 oil will flow better when the engine is cold, followed by 5W-40, and then 10W-40.

It looks like with the time constraints, I'll have to get either mobil oil from GL Lubricants, or other brands from 'standard' places like: repco, supercheap, autobarn, etc.. Unless there is somewhere better on a Sat Morn?

Given the same price, I'd go with M1 0W-40, but any synthetic 5W-40 oil will be fine as well. And unless you're experiencing significant issues with oil consumption or leakage, then you don't really need a 10W-40 oil.

[kendog]

Awesome! Mega Thanks!!!

Hey mate,
On my last service (exact same car as yours) I used the Castrol Edge 5W-30 A3/B4 from repco and seems to be fine. I'd also reccomend getting some injector cleaner fluid. Basically just add half the bottle in your tank when it's empty and put a full tank of high octane petrol in.
