Splash Pans

I don't know if your 260 had one , although my build date 8/73 '73 240 does . They are NLA as far as I know. Most of them have been removed and tossed. Like the hub caps . They do help to keep the engine bay cleaner and I have read that it helps to allow the air that builds up under the front of the car at speed , to exit back under and out and they increase the air flow through the radiator. I don't know if any of the air stuff is true but I did feel the difference in how the car felt when I pulled it off and ran her up to 95 , then installed it did it again. It could be a case like seat of the pants dyno telling me it is better, I don't know. LOL I will say that I read the information AFTER I tried the on off test. I had just removed the pan to clean it and paint it . Then a couple of days later I installed it and drove over the same stretch of hi-way . A month or so later I read the article . Gary :surprised

They do make a difference when it comes to engine bay cleanliness. I've still got to put mine back on.

Because they were often removed and forgotten about, you can find them once in a while on ebay, but you might get a hit from someone with a parts car on here.

I have a photo of one for a 240Z from a topic here some while back ( I saved it to my hard drive on 4/11/2005).

I might consider making one for my 280Z if I could find a photo. I think I saw some bolt holes under there that I didn't recognize- I'll have to go look again.

Tomohawk-

My '76 has a splash pan. I could send you some pics of it if you'd like... I still haven't put it back on after replacing the radiator back in April... I should get around to that... hrm...

It might be hit or miss though seeing as Gary said the pans changed from 71 to 73... No reason to think it couldn't have changed from 76 to 78...

Tomohawk, you should hook up with alissa280z in Ct. She's parting out a 78 and maybe it has the splash pan. My 78 has one and others I've checked also do. Yours probably got lost/misplaced by a previous owner.

I guess Datsun and other technicians in the states thought they were smarter than the engineers back in Japan. Engineers don't strap on stuff with no purpose. Engineers are not trained to add gimics. If you see gimics, that's the marketing executives forcing engineers to put them on. Trust me, I know. That pan was there for a good reason, and so was the fan cowl on the radiator. The buffeting of air flow under the radiator fan blade area is disruptive to the airflow the cools the radiator. Turbulence is undesireable. But who can convince some of these automotive technicians who want to play automotive design engineer?

I have one that I purchased from someone, but have not installed it yet. I did put a ton of paint on it.

Tomohawk, have you held one of these pans in your hands. I'll tell you that this is a very complex sheetmetal stamping. I started taking measurements to make a pattern and gave up, and I'm an engineer. You might be able with much time to make a primitive one. I'll say it again, this stamping is VERY complex.

Man, I've been searching for one of these splash pans for my 1970 for a while and have resulted zippo!!! So, anyone with a lead on finding and purchasing one, please notify me.....It would be greatly appreciated!

I bought one of those pans a while back from Nissan Motosport for my C Production 240Z race car. They said they were NLA for 240Zs, so I went ahead and ordered one for a 260/280Z with the hope I could modify it to fit. They said I'd purchased the last new one available through Nissan in the country.

Long story short, I had to bend it up on the front edge to fit my car. I tried it out at California Speedway, where in the past my front end got so light through turns 1 and 2 that I could steer the car with one finger. Now with the increased downforce, I need two fingers to steer the car through those turns.

Any one in the Portland area that has a 280 with a splash pan ? I recently needed to replace my 240 radiator and I installed a 3 core 280 unit. As you know they extend down below the radiator support about 2'' . The 240 splash pan will not fit any longer unless I make a couple of cuts and reshape the front of it , when I add the 2'' filler that will protect the tank. I really dislike cutting into the stock pan and was wondering if some one had a 280 that I could compare to and see if I could make one of those work. I am going to look at the bone yard for one , but I don't get to them vary often any more as the local ones rarely have any Zs . Gary :bandit:

When it gets to be that crazy, I get out the aluminum foil. You can tape sheets together to make bigger sheets, and it's infinitely shape-able. Finally, you can flatten out the whole mess, and lay it out on carboard, then metal.

Okay, fair enough. I just thought, based on the above comment, that rather than attempting to make one, you might be inerested in getting the one that was designed for your car especially when she's giving it away for the cost of postage.

When I purchased my 72 Datsun 240Z, it was equipped with a 280Z radiator that extended below the clip. The splash pan was missing. I was able to locate one in California (the owner had removed it because it was in the way. It was in almost new condition.).

I removed the 280Z radiator and purchased one from US Radiator (Five core high efficiency. They also manufacture the "Dessert Cooler" and triple cross-flow radiator).

I then installed the splash pan. I have had no overheating problems (even at the Dallas/Ft. Worth ZCCA Convention the end of May and first week in June).

The temperatures were constantly 95+ degrees F. Includes a lot of slow city driving with long periods if idling.
