Replaced mine today with one from Repco (90 marked on it), the repco one has a spring and guff on it where it goes into the top of rad, where the nissan one has no spring etc.

Whats the difference? Is the repco one any good, or will it screw things up?

thanks

trucky, Mate, don't put one with spring onto YOUR radiator. On your model there is a remote plastic tank on the left side inner guard which is part of the pressurised system. THAT tank should have the sprung cap, not the radiator itself.

Mate, you should be able to use the new one on top of the expansion tank okay

Eh! Roachie

Do you have 'white stuff' around yours.

Wouldn't have thought so as the only egg you have experienced is the egg on your face.

Hey! Des it's just to much isn't it.

ROF with tears in my eyes LMAO.

PS

See you all in March.

I'm not exactly answering your question Truckster, but I would be wary. A couple of years ago I had a new radiator installed by Natrad. It had a non standard cap. A few months later, weld went on the radiator. Turns out that the cap didn't meet the pressure specs it claimed. Built up considerably more pressure and split welds.

With my radiator issues lately, kinda interested in the post responses going to come here. My radiator cap has a spring in it (its a prado tho). Presuming different cars have diff ways of keeping pressure.

Toyota and Nissan radiator caps last way better than any of the aftermarket caps. They are a relatively cheap and very important item - I'd buy genuine every time.

I am amazed, nup! rephrase that - p i s s e d and amazed.

I find it amazing that you cootas who continually profess to be the experts on all things 4WD wise, and anything else wise aren't so forthcomming when it comes to the good old simple RADIATOR CAP.

One of you above gentleman had it 95% right ie there are two different style of radiatorcaps.

(a) Those for re-circulating systems

(b) Those for non recirculating systems.

The other critical factor is the pressure rating, not the temp rating.

Nearly all vehicles have different setups and specs for each model, so you have to see what the OEM specs are for your vehicle.

Now if you have 'tweaked' fuel, tune, turbo, pump etc you MAY have to compensate for extra heat with a higher presure cap.

Remember the sytem has to be water/presurised tight as escaping fluid lowers the presure resulting in O-heating, leading to possible boiling, which will see you in endless doo-doo.

There is no one fix for all

Lucy,
I haven't seen a non-recirculating system for over 15 years.
There is one fix for all - get a genuine cap!

Aw! Now you have gone and done it Phil G.

Made me sound as if I am 35 +. (LOL)

Had to mention both as they still sell caps for both and catch out those that aren't aware of the diff.

Also the comments from all, re genuine product are spot on with the more up to date technology vehicles and it goes back to the OEM vehicle engineering design.

Though that has been known to be faulty on the odd occassion.

The company who makes the caps which are sold in repco and supersh@t, also make most of the genuine ones for the car company's. BUT the after market ones have mostly plastic internals where as the genuine ones are brass or steel internals on the caps......from the same manufacturer!!!! This was told to me by my local radiator guy who showed me the difference in quality. Was also told the repco ones are also unreliable, sometimes hold to much pressure, sometimes not enough......my advice is buy genuine there is a difference

Stefan,
I agree - been stung by crappy aftermarket caps in the past. Genuine ones last a long time, and are unlikely to overpressure.

Truckster,
I replaced mine late last year (1995 80 series Petrol). For $8.90 for a genuine Toyota Cap (Preston Toyota) I wouldn't risk a non genuine item. I still have the old one which works fine but thought being 12 years old wouldn't hurt to change it.
I boutght a Repco fuel filter for the cruiser a few years ago and although the banjo fittings worked fine, the mounting holes where the filter mounts to the engine did not line up. I had to drill out the holes on the filter to make it fit. Needless to say I never have bought non genuine stuff again, except for brake pads which I use Bosch.
