Aluminum Radiator?

[RavenTai]

-B- that is a nice guage and a clean install, did you document the install on the board somewhere? where did you put the sender?

are the bugs adjustable or preset?

 

[turbocruiser]

Great suggestions guys, what I want is both an EGT gauge and a coolant temp gauge. I'd like to find one that is rectangular and would fit in the spot under my cd-deck since I do not have much more room for gauges on my roof pillar!!! Do you know of any rectangular gauge that would have those two functions? Thanks again, great suggestions.

The sender is in the water neck just behind the alternator. I copied Photoman's install so it wouldn't be right for me to take credit. Here is a picture of his water neck which he graciously exchanged with my original water neck. (Thanks again Bill !! )

are the bugs adjustable or preset?

The bugs are water residue.

Used the same info for location for the sender. Drilled, tapped, and installed the sender with the neck in place on a fully charged system. Takes under 5 min and lost less then a ½ pint of fluid.
It is amazing what a POS the OEM gauge is.

I'd like to use that same location for my gauge as well but unfortunately, that is where one of the return fittings for the coolant that comes out of the turbo goes. I'm running out of places perfect for tapping into. I wonder if I can find a fitting that would "T" so that I can add a tap for a gauge AND for the turbo that same spot?

That fitting is cast aluminum. Find an expert welder who can deal with cast aluminum. Have another bung welded on. Drill & tap. Not a job for the average welder.

Yes, but one more reason for me to get the TIG welder I've wanted forever!!! Sure honey, having a pro do this will cost 1500 while the TIG is ooonnnnlllllyyyyyyy 1300! Thanks though, short of finding some fitting that tees, seems like this is the only way to go. Hey, btw, let me ask this thing from another angle ... is it only the gauge that is purposely flat spotted? In other words, is there a way to use the wires and sensor for the factory gauge, and cut and splice them into an aftermarket one? Or, better yet, is there a way to electronically erase that flat spot feature and create an accurate and linear gauge out of the factory gauge? I think this is what MTS was referring to but I do not know how to go about that, and I guess, all things equal I'd still rather have really accurate aftermarket gauge but use the existing temp sensor and wiring and whatsnot. Problem is I do not know if the existing temp sensor is the problem, or if its the gauge or both? Thanks guys.

In *theory* it should be the gauge that is the issue. I have "linearized" the OEM gauge on my track car. You should be able to do it with the LC gauge as well if you want to dig into it. Unfortunately, I can't tell you which resistors to use. Someone I know did all the experimenting for me and I just followed his instructions when doing mine. The basic principles are here:

Perhaps there's an EE on this board that might want to dig into it?

And as far as getting your coolant temp goes, G'Reddy makes this blue deal at the bottom of this page that, I believe, fits the 80 that would be totally easy to install (radiator temp attachment unit with sensor/probe hole already in place :

Actually Mot, that is super helpful, thanks. I had a hard time with the Japanese though, can you tell me where to get this stateside? Thanks again, I think you are onto something!

there are some outward sililarities between that Miata guage and the LC guage including the needle the two screw and the water temp symbol, major diffrence one is horizontal the other verticle and the LC version is bolted to a common plate with the oil pressure guage, I wonder if they are from the same sub-contractor? Aisin? hopefully electrically the same or similar

https://forum.ih8mud.com/showthread.php?t=11451

there were some charts of the reaction of the sensor in that thread, but they were lost in the software change IIRC the curve was similar to what is shown on that miata site,

 

[Rich]

Here is the graph I previously posted. It only goes to 210 degrees as I tested in a water bath. Bill has a graph that goes higher.

 

[Rich]

Does anyone have a salvage instrument panel for exploring the development of a mod similiar to that posted by Mike for Miatas?

 

[mot]

turbo,

This is their US site. I glanced at it quickly, but could not find anything like what I found in their Japenese site.

http://www.greddy.com

Do try go through it more thoroughly than I did and if you don't find it, then you might want to contact them. If they say that they can't get it and if you are still interested, let me know. I would be willing to help!

Let us know what you find out.

turbo,

I did a little more research and have found that a guy driving a '95 FZJ was using G'Reddy's 38φ (Product code: 16401638) and the retail price on their site shows about $30US.

Please confirm your hose diameter and confirm with G'Reddy US that they are accurate and that it would work on your rig.

HTH.

Good luck!

Mot, you rock man, thanks so much!!! I'll follow up on that asap. Thanks again.

This is linking back to the awesome and awesomely simple suggestion from Mot on how to add an aftermarket coolant temp sensor even though the factory "extra" location on that aluminum neck off the engine on my rig is taken up with the line for the coolant that goes to the turbo. I'm gonna try to post a pic of this thing here but sometimes have a hard time doing that. This adaptor thing is only 28 dollars and the correct corresponding celsius gauge is only like 55 dollars. The other cool thing about the gauge is that it is self-grounding which makes the install about as easy as easy gets!!! Anyway, I was thinking that for those that want an easy and effective way to add an aftermarket coolant temp sensor setup to their rigs without drilling and tapping that aluminum neck, this thing might be the trick. I want to go out of my way to say that this trick is not my brainchild (dont know if my brain could give birth to such a thing!) and to add that Mot really helped out by offering this info. Thanks again MOT, you totally rock man!!! I will write with results when I get this shipped to me and situated on my rig.

turbo,

I can't take all the credit! As it says in the good book, "Ask and ye shall receive", you received good information received from several individuals This is what makes this forum so great!

So does that mean that it was officially offered on their website or did you have to give them the part number, etc... to see if that's something that they could get from Japan?

In any case, I'm really happy that it seems like you are well on your way to get your coolant temp gauge/sensor properly installed.

Please do keep us posted on your progress.

Cheers,

Mot

... and the correct corresponding celsius gauge is only like 55 dollars.

The picture of the gauge that I posted (also used by Photoman) is a *lot* more than $55. I believe list is around $210; found new on eBay for ~$100.
