got everything done with the timing chain, water pump, timing cover, and AM1 fuse... i know the oil pump is easily removable, but what is the easiest way without pulling the radiator off (again)? im sure im over complicating this but im stressed, burnt out from work, and want it done. i FINALLY have a weekend off and just wanted a quick solution... i even have permission from the wife!

Teuf

No shortcuts my friend. Have a beer slow down, take of the radiator.

spaseghost

beer is no problem, the radiator is. thanks for the help. side question; i like dexcool, does anybody know if its problematic in this system? i know they can get frothy in GMs...

Teuf

I would, and do, run prestone green, so if you need some on the trail its the most popular.
Why is a radiator so hard to remove. The more hands on you are, the more you can see potential probs. I did my radiator 3 times once, because of a goof I made, good thing a hose was about to burst.

spaseghost

green is more readily available, and cheaper. ive just got a ton of dexcool sadly.
yeah, i can do it. but id rather just drive it. oh well, maybe i can do a write up on it for the kids or something. thanks for the replies man, love your skid plate too!

Teuf

Ah OK thanks

Engh! Don't run the Dexcool! Exchange, give to an enemy, whatever, don't use it. Run a search on sb5walker coolant posts. I don't remember all the details, but you should read about it.

Teuf

Global would be OK yes?

thook

Sorry, man. Don't know what that is. I assume it's coolant, but I've never heard of it.

thook

I just looked it up. According to sb5walker's info, it was either HOAT or OAT type coolants weren't good for these motors. Run a search, Teuf. His posting about it's not too old. I'm going to have read more myself. I only briefly read it catching a few major points.

Teuf

Global is yellow and universal, so supposed to mix with all.

thook

Okay. Whatever you say, Teuf. Maybe read on it a little bit, though.

Teuf

Well I stay with green, and to think I worked in NH for an antifreeze recycle Co.

I replaced the oil pump and drive gear on my 86 4Runner (22RE) and i didn`t remove the radiator to do it. As long as you can get the crank shaft bolt out and the balancer off the rest is easy.

spaseghost

spaces are tight in there, im not as flexable as i used to be... but i think i can pull the fan and shroud and be okay.
also, i found that green coolant hides in the back corner of my garage in two unopened jugs with no labels. guess im doin a flush too. still got my trd 160 thermostat from my celica, might drop that in just cause. anyways, thanks for the help everyone!
doesnt audi use pink coolant, or is it porsche?

Teuf

I think a 160 is to low a thermostat to run. My 180 ran way cool, and was kinda actin strange. A dual stage toyota T stat fixed that.

thook

Haha....I know what you mean. But, eh....so what, right? I use propylene glycol. No rust issues, the coolant lasts a full two years, atleast. And, hey....it's low tox for the critters. Prestone green. If I was gonna switch, I'd go Toyota red, though.


Toyota thermostat, ftw. It's crazy, but seems to be true. I spoke with a fellow who spoke with the head tech at the local dealer when I asked about the necessity. Didn't go into a lot of detail, but basically if the thermo opens too soon, the motor doesn't reach operating temp as quickly. As well, the thermo regulates temp. So, since operating temp is higher on the 22re.....EFI being regulated by engines temps.....you have to have a thermo that will keep the temps up there. There's more to it than this. Not much more, but I'm too tired to explain any further....

dude, that freakin thermostat was $56 bucks! its all in chineese or whatever too... guess ill put it up on craigslist or soemthing.

Dex cool was used in GM vehicles and the problem is that it is super corrosive and it gunked up the cooling systems and chewed up gaskets. I know this because I used to have and old 2000 Pontiac Bonneville which came with dex cool from the factory and it was nasty stuff. I think the recommended change interval on the Dex cool was like 5 years or 100K miles. I would just use green or toyota red coolant.

I'm approaching 95K miles or so on my 22RE, and was thinking of doing the t-chain before school and winter.

I'm busy buying all Toyota parts online, but will probably go with the recommended metal-backed DOA guides.

I was just wondering if it's a safer bet to replace the oil pump at the same time as you slap on the new timing chain, or are the existing units pretty reliable (I would of course partscleaner and clean up the old one if reused).

This 22RE has never really been abused, but I'm just curious if it's a good idea for the oil pump to go?

Thanks!
