Series 1 motor with series 2 radiator, can it work?

[DAVIDC]

Hey guys,
I've run into a bit of trouble with project aero, while putting the series 2 motor into the series 1 shell, I decided to keep the series 1 radiator and heater tap? the whole system pretty much.
I'm just running into a lot a problems with connecting shit, and the books I have don't show you how to connect series 1 stuff to series 2 motors.

Is it just easier getting the whole series 2 radiator system and chucking that in?
Any help/ideas/hate would be appreciated!

I had a S2 radiator on a S1 motor = fail. Had serious coolant drinking problem.

If your fitting a S2 motor I would get all the S2 stuff from the wreckers and fit that in. Less chance of issues.

See, I gave my mate a S2 radiator for his S1, and he hasn't had any problems so far : |

any bumping?

just for future reference, as i came here looking for an answer to the above question but was unsuccessfull i decided what the hell and gave it a try, the answer is YES a series 2 radiator will work with a vn series 1, make sure you use a new radiator cap CPC part 538-20 rated at 135kpa, when topping up the coolant leave the cap off the header tank and the radiator slowly fill both until you cant get anymore water in their, then put the caps back on, i drove my car for a good 15 minutes got it upto running temp then let it idle for 15 or so minutes to make sure i had correct operation of my thermo fan and nothing stupid was happening (water leaks etc) and all seems fine, when car has cooled top up header tap and radiator if necessary.

sure you can put it in... it's not designed for it though, the s2 engine has a bleeder to remove air from the system on the thermostat housing, the s1 engine and system automatically bleeds the air as it's always circulating coolant through the bottle where you fill it.... 2 completely different systems... as a s1 is 22-24 years old now and the radiator is probably just about stuffed, buy a s2/vp/vr radiator and throw that in there to suit the engine.

From memory, I used the complete Series 2 coolant system but had heaps of trouble with the heater tap. Got it working though, so it can be done. Defiantly would not do it again though, just does not seem worth it when it should be such a simple thing :P

whats the best coolant to use in the Vn S1 radiator?

Is there another way to fill the radiator besides using the overflow container?

[Jxw]

i've been using nulon concentrate (small bottle) and the rest water for a long time with good results, once again it's not an overflow bottle (the one on the drivers side with the screw cap?), it's part of the cooling system, some vn s1's had a separate overflow bottle on the passenger side of the engine bay from memory but i've only ever seen pictures of this and never one when poking my head under the hood.

[sapeter]

only reason is because i dont have a cap on the radiator.. (radiator with no cap)

so if i get another radiator with a cap would that do the job?

Nulon Concentrate << Is that the proper name for the coolant?

[Jxw]

s1 vn didn't have a cap on the radiator, the fill point is the res, burson's have the correct cap for this... forget how much they are though.

nulon ethylene glycol, comes in a small bottle (500-600ml or similar, is a dark green color)
