if i could find an a14 fan and stuff. got an a12 one but even with pully and spacer, the holes are different spacing. weird.

Quote:Like this?



You can fit the A14 fan on it (negative offset fan)



just need the pully and spacer

thermostat is new ish, was new when installed, but the rad seems ok by using the hand test of temp across the core when hot.

Only issue with changing the clutch fan for a normal one means replacing the water pump, the stud hole spacing is different for clutch fan and normal fan on the water pumps.

might just do that as i have to drain the coolant any way, also do the thermo stat and see.

Yes, could be anything. Easy test is put the stock fan (non-clutch) back on. Work better?

My radiator was heating up more than normal this past summer. I took it out and spent two hours pulling pine needles out of the fins, and straightening the fins. But now it's too cold to tell if it makes any difference...

It could be anything Mik. How old is the thermostat. Even new ones have been known to fail. Even the radiator cap not holding enough pressure can cause overheating. Too many variables. Although radiators can block up over time, the way to check one is to measure the temperature over the entire radiator and check for cold patches. Another thing is that the way you piss around with the tune of your engine a while ago it could be that the LPG is running a bit lean. LPG combustion temperature is much higher than petrol. LPG engines as a rule run hotter than petrol anyway. By at least 10%.

ok i might swap in the ca radiator but need to make an extension pipe for bottom tank as it s on opposite side.

would galvanised pipe do the trick? only need about 10cm of it.

Having some ebay trouble re my intake piping, once thats sorted I've just got to knock off some wiring....hadn't touched it for almost 1/2 a year now finally getting back into finishing it (new baby in the house and I spend a couple of months OS...there my excuses anyway)

Looking forward to hearing it start soon.

could the fan be on backwards? i've used auto cooling for lots of datsun and other stuff, good blokes. Mildman, how's that CA conversion going?...

I use Auto Cooling in Clayton, (probably a bit far for you Mik) but for $40 he'll acid dip it and let it soak overnight, then flush it out and respray it black. Pretty cheap.

Last one I had done was the 'rana rad - was $75 but that included pulling off the top tank and rewelding it on again.

A new core would be more like $200+ out of interest.

Yea, I agree. Can be starting to clog up.
I had mine re cored a while back and just last weekend I checked into the radiator cap with a flashlight to see how the cores look. I just hate that they are such thin pipes.
They have small stuff that look like old rust particles partially blocking some of the core pipes. I just hate this small flattened pipe cores.

What radiator do you have in currently?
When I get it cleaned in the future again I will use that trick Dodgeman mentioned of cheese cloth in the top pipe for a couple of weeks to catch the crud that would possibly have started to block the core again.
