Make sure to check if there is a voltage in the coolant, else it wont last too long.

How?

You need a multimeter set it to Voltage DC, with the car running put the negative test lead to the chassis(better to the neg of the battery). Put the positive lead into your coolant via where the cap is, be careful that its only submerged into coolant and that its not touching no metal. If you get a reading > 0.3VDC you have a problem and the radiator wont last very long.

If you get a reading over 0.3VDC make sure you replace your coolant, try the test again after replacement.

Grounding the radiator wont cure the problem! You need to find the faulty circuit which is inducing the stray voltage. Start removing fuses until you find the voltage drop, then its a matter of adding a bigger ground for the found bad circuit.

Try googling "aluminum radiator electrolysis" if you are after more information.

*You will need to go to supercheap and buy 3 copper washers for the temp sensor.

Ok a bit confused here. I had my alloy radiator fitted several months ago and I didn't need any washers. In fact, there was nothing connected to the radiator other than top and bottom hoses. weren't any holes in the new rad either for a temp sensor to slide into.

anyone care to shed some light?

also, car takes a VERY long time to warm up in the morning. temp hits normal after a good 5km of driving, so about 15 minutes. is this normal? i have a nismo cap on it (1.3 bar).

Think his talking about the water coolant temp sensor located just after the end of the top radiator hose (engine side).

Don't understand why you would need washers there.

    • Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
    • My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
    • The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.
    • Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
    • Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
