Aftermarket or OEM Parts?

[Vandals909]

Well the wifes 1998 2.2l water pump went out. The car has a small oil leak, so while I'm in there plan the replace the following as we purchased the vehicle with 71k and now it has 151k. Only thing we have done to it was new thermostat, and one timing belt.

Replacement list

1. Timing Belt
2. Idler
3. cam seal
4. crank seal
5. oil pump seal
6. oil pump o-ring
7 water pump
8. tensioner
9. water pump gasket (not sure if new pump comes with one)
10. Tensioner Spring

My questions is, what should I buy as OEM parts or arftermarket?

I planned on getting the OEM waterpump and timing belt.

Was more wondering what kind of experience people have had with after market seal/gaskets and idler and tensioners?


Thanks!

I vote for OEM. This job is very labor intensive and I don't want to redo it just because aftermarket part gave up too soon. Check partznet.com for not expensive OEM parts.

I know drivewire.com sells a kit for the V6 with OEM parts (212$ + shipping), you just have to be patient with their interface... Look around and there is bound to be one for the I4. I vote for OEM as well, as nervous stated, this is labor intensive, you'll probably end up paying more in labor than you do in parts, so this is not something you want to do twice. If you want to check out some more OEM dealers, here is a thread:

Best prices on OEM parts online??

The prices for each one are ballpark in the same area, but much cheaper than the dealership. Typically, aftermarket idlers won't last as long as OEM idlers would. I pulled 210,000 miles out of my V6's original tensioner bearing!! For me, it's worth the extra couple of bucks... Good luck!

i recommend buying any powertrain/engine related part, stay with OEM, and if you buy them from online dealer, it will be like 25% off list from www.toyotaoemparts.com, www.partznet.com, etc
it doesn't matter how much cheaper aftermarket parts are, and how well they describe the product such as lifetime guarrantee, i found most aftermarket parts in term of quality, still fall short compare to oem

The dealer (OEM) parts are made by a supplier, so if you choose to go to a parts store, check that the supplier is an OEM provider.

1. Timing Belt - Dealer or Bando, Mitsuboshi Try to get one marked HSNBR (highly saturated nitrile rubber) it is more durable, and should not cost any more then the HTN belt.
2. Idler - Dealer or NSK, Koyo marked on the rubber seal
3. cam seal - Dealer
4. crank seal - Dealer
5. oil pump seal - Dealer
6. oil pump o-ring - Dealer
7 water pump - Dealer or Aisin
8. tensioner - Dealer or NSK, Koyo
9. water pump gasket (not sure if new pump comes with one) - should come with one, if not, dealer.
10. Tensioner Spring - Dealer

I have a militant dislike of aftermarket parts for anything mission-critical (based on seeing too many crap Chinese-made parts give up the ghost in less than a year). However, I've used parts made by Toyotas OEM suppliers in a number of rigs, and have always been impressed with the quality. There used to be a dealer on fleabay (volkstoy) that sold an very nice kit with all the stuff (including oil seals) that you'd want to replace while you were in the timing belt area...Aisin water pump, Mitsuboshi belt, etc. Very high quality. Problem is, I haven't seen them listing the 2.2L kit for a few months. There are other fleabay dealers that seem to list the same sort of kit and parts, but I have no personal experience with them.

1. Timing Belt

Yes get OEM.

2. Idler

On the V6 there are two idlers, "#1 idler" is ONLY available OEM. On the 4 i think there is one im not sure. Price them first if they are available aftermarket (yes OEM may be better quality but remember toyota does NOT make their own idlers, or many other parts in house - they buy from suppliers just like we do!)

3. cam seal, crank seal, oil pump seal, oil pump o-ring
price em first , go with OEM if difference is not significant

7 water pump
OEM is better, but the price difference is often significant. The only two parts to worry about long haul, are the seal and bearing, of course you want the longest lasting one - Napa online sells a very good water pump.

8. tensioner
Go by price

9. water pump gasket (not sure if new pump comes with one)
OEM! Mine didn't come with a gasket, but i didn't use an OEM water pump, i got one off the internet. If you buy yours from the store, just look in the box when you buy the pump. OEM can't cost much more, and you know its the right type and will fit. When i did my V6 timing belt, the replacement gasket was aftermarket paper material that needs sealer, and very inferior to the stock stainless steel and neoprene OEM gasket. I reused the old one for that reason, next time i will buy a new OEM gasket.

10. Tensioner Spring
Price them - but i'd lean toward OEM.

You can get OEM for about the same price as aftermarket parts. So for most people I think that's fine. For example, why would a Denso spark plug be different from the dealer or the parts store? Except you don't get free coffee at the parts store.

I personally prefer Gates belts and hoses over GoodYear, Dayco, Mitsuboshi and Bando (the last three often in OEM parts bin). OEM water pump is made by Aisin. You'd likely get the same Koyo idler in the Gates package as OEM, but a Korean GMB tensioner pulley. Don't have problems if you pick your aftermarket parts carefully and not get the cheapest parts store special.
Again, for most people, water pump, thermostat and coolant definitely OEM only, with distilled water. I spec NAPA pumps without problems however.

The following is an example of parts that I would spec, but if OEM online costs the same, then why not? Use what makes you sleep at night.

GATES TCK199 (kit of timing belt with two pulleys and instruction)

OEM for critical parts like this. I've seen countless threads on this forum from people complaining that they're after market pumps failed after 20k. It could turn into a huge headache later.

I'm about to do the same thing but for a 96 2.2L, I was wondering whats the differences between the water pump with the housing and w/o. And which water pump gasket? There were a few different choices but no real clear description. There were two kinds of water pumps AISIN Part # WPT010A and AISIN Part # WPTK010, whats the differences? Thanks

You mean I4 right? LOL

[73sport]

I vote OEM - toyo makes good stuff! After market just aint the same.

On another note related to this repair:

If you use paper type gaskets that retain oil or water i.e. made of cork or some other porous paper like material do the following:

Spay all paper gaskets with Copper Coat! Spray all sides of them (edges too). If you don't have the good stuff, use a rattle can of GLOSS paint! This action will keep your paper gaskets from weeping fluids! I think permatex makes that product.

[ldanny]

LOL.. sorry, im a noobie. hehe in any case, its a 1996 DX.. I was looking on rockauto.com for the water pump.


do you have to wait for the coat on the gasket to dry before you install?

[JohnGD]

The 010A part is $10 more than the K010. However, the picture of the K010 shows the pump housing too. I checked Aisin Aftermarket's website, but no catalogs that I could find in the short time I browsed.

A pump should come with a gasket. That's the large one between the pump and its housing. But looks like Aisin also includes the smaller ones for the housing to the block.

You don't need the housing. Unless you want to replace it too while getting at the gaskets (they should be replace while in there). If it's still the older fiber gasket then yes, you need to use water pump RTV, such as the Permatex stuff:

I'd use business card thickness both sides and apply within the specified time.
