Hey all

I was just wondering how you guys go about cleaning the lenses on the headlights and how you get the lenses off. Ive taken all those little clips off and some screws but the fugger doesnt seem to wanna come off. Is there a nack with it or do you just try and lever it apart because the glue is being a pain in the a$$ to get it apart.

Any ideas?

Cheers

I get the feeling those clips only held the light together while the glue set. Some people say you have to heat it up somehow (water/hairdryer) to pull it apart slowly.

Mine are fairly old and were fairly dirty I just just autosol'led the outside and they were fine - should give that a go before you go to the trouble of taking them apart :)

You can take the front lens off but I wouldn't. Mine had a run from some sort of solvent and they were smokey/foggy looking.

I was convinced that the front was as clean as it could get and the inside must be dirty and so I took one apart (after buying a nice pair from a 4 door).

It is a big job to get one apart and is going to be a bigger job getting it back together.

I will be trying the various cutting compound type products now (watching this space for the best performer).

u can not take the lense off, there is a way but you gotta reseal it, i bought a jap cleaner thing that makes a shit lot of difference.

If the R33 is anything like the R32 -- and I imagine it is -- its quite easy to get the front glass/lens off, but it involves breaking the sealant so you will have to reseal them.

A hairdryer is a very bad idea: the heat is too directional and you'll end up either not getting the area hot enough, or melting the plastic.

If you really want to pull apart your headlight, you need to..:

1) Preheat your over to 200 degrees celcius.

2) Turn the oven off.

3) Place your headlight on a rack (that hasn't been sitting in the oven).

4) Put the rack+headlight in to the over, making sure the headlight doesn't touch the sides of the oven.

5) Set a timer for 10 minutes. After 10 minutes, yank the headlight out.

6) Using a blunt bread knife, run the knife in the join between the glass and the rear of the headlight. The trick is to try and cut through the sealant, and gently work the two apart.

pretty sure there are a couple of old threads on this.

before trying to take em apart, i'd definately try a few methods of cleaning. i use toothpaste (sounds dumb but does the job :) ) and a heap of elbow grease and they come up well. the other thing i have done is gone to a panelbeater and got them to basically cut and polish the cover, looked brand new.

if these don't work, then try the oven trick.

I use Meguiar's "PLASTIX" clear plastic cleaner & polish... $18 at CrappyBarn!

Yep, this stuff works a treat. I thought the hazyness was on the inside but after using plastX, it seemed to only be on the outside.

on an r33 the front lens is plastic not glass so im not sure if it is a good idea.

The majority of an R32 headlight is plastic too. The point is not to melt the plastic -- it merely gets hot, and hence you turn the oven off and place the headlight on a cold rack -- its too soften the binding agent.

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
