i have used a gemini one in the ute and coupe... worked a treat... trying to find a good one for the sedan.... have a 4agze one i may try but top hose points the wrong way from a plastic top tank.

a few guys use the pulsar n14 one with good results, especailly on 12a rotors...

Cheezcloth as a filter??? I never thought of that! Do you think that it might rip or come apart and plug up a cooling jackets or radiator tubes? What about some type of metal screen? I'm assuming you're putting this over the inlet side of the radiator, correct? You know, it makes me wonder why no-one has ever produced a coolant filter before. Thanks for the idea!

OH, and Curtis, since I live in one of the hotest cities in the US, I would say the more radiator the better to beat the heat, but then again... it is a dry heat!!!

I bought a filter from a radiator shop & it looks like a cheesecloth condom. [Do not use it for this purpose] They were available in small & large sizes & I bought the small one.
You slide it into the top tank, up the inlet fitting & fold the end over the outside of top tank's hose fitting, then slide the radiator hose over that.
In my case, there was enough material left over to fold some back over the outside of the hose, then I fitted the clamp around the whole lot.

I have pulled it out about four times in the last year & a bit, about every three to six months, & was amazed at just how much crud was trapped inside, but it was protecting my new radiator core, so I was happy.

Simply turn inside out, then wash it & reinstall. Works for me.

I'll pass this along as a fellow desert dweller. Our 1200 had a total rebuilt engine (stock) and a new radiator when I went to SCCA drivers school and I ended up having to run the heater in the afternoon..........the car would get 7/8ths hot. It was late May and temps were about 104-106 range. A B210 or 210 radiator should do the trick for a stocker. I use the Nissan 3 core radiator for the 1200 and it the car runs about 220 if I buzz the full 8000 RPMs at the track........running only 7800 RPM's and the water temp goes down to 210. My experiance has been early Datsuns run hot , don't overheat but definetly in the upper end of the temp gauge.

Can you get the filters from a standard auto parts store or do you think it has to come from a radiator shop? I'm for sure going to use one. You can never have too much protection!
Considering that I live in AZ, I'm installing AC, and eventually want to put in an A15, I want to install the biggest radiator I can fit in there.
Thanks everyone for the info.
