Put the year of your 510 in you profile.

 

Assume this is for your PL510? Any L4 or L6 cylinder engine will do through '78.  From '79 on the thermostat housing uses 3 bolts.

Im sorry Mike. I have a 1971 Datsun 510 1600 c motor. The housing neck uses two bolts. Its a L1600.

Thanks

Fixed your profile. Then any L series through '78 will work.

Hi Mike. Only Thermostat housing cover I can find near me is for a 1976 Datsun pick up. Problem is it has three bolt holes. My question is cn I use this?

Try Korean car parts, They often fit older Japanese cars, I have a Sephia thermostat housing neck on my 67RL411.  Slightly shorter on the height but works. I had the ream the mounting holes up from metric to SAE but that's all it took.

Three bolt housings only came on the '79 and 90 L engines so it it the engine has been swapped.

 

YES! you can use the three bolt top cover if you also swap the three bolt thermostat housing on to match. Here's mine. I did glue some 180 grit sandpaper on a sheet of glass and passed all three surfaces over it to true them up. No way a gasket won't seal now.

 

 

Avoid using RTV on gaskets. Sealing is what the gasket does! RTV is only for severe cases where the surfaces might be damaged. That crap squeezes out and looks amateurish, but also squeezes inwards and plugs the rad and cooling holes in the head. 90% of RTV used never needed it. The rule is: If it has a gasket.... it doesn't need RTV.

Hi. Well I cheated a little. I found a water outlet on eBay and they showed the part number on the picture. The part number is 11060 u0100 and you can order it at Nissan Dealers. It's 27.86 plus tax. Also I found it on Nissans.com for 20.00 I still have to pull the head this afternoon but I thought I would share this. Also if you want to verify this google the part number.

Thanks

Be sure to secure the timing chain tensioner so it can't fall out when the chain goes slack.

zcarparts.com has them.

I think I even seen rockauto and maybe parts geek

use antiseize on all water parts like this ans water pump. helps from the rust. I do all bolts in alum esp sparksplugs

 

I would get a spare lower houseing also with the 16mm nut to hold the sender as spare. Mine alwasy cracked when trying to get the sender out. or get a whole used unit that works
