Capless Radiator Wtf!

[Keesh]

um just got a second handy radiator.. the bloody thing has no cap! now i was thinking maybe its off a later model? is this going to be a problem or is there an overflow valve built in(hense not needing the cap)? it hooks up the same and has the standard v6 fan im thinking vs?

[vk_calais5.0]

can't you just buy a cap from your local servo, or have i got it all wrong-capless??

[vq~gangsta]

I know that the radiators off some of the newer cars don't have a radiator cap, they basically just get filled up from the reservoir / overflow tank, i think it's a safety feature to stop retarded people from opening the cap while the engine's hot.

[Keesh]

nah u miss read.. im a parts interperator at holden, i know where to get caps! haha nah theres no spot for the cap.. none at all, i dont think its a problem cause u fill up the overflow, but i havnt seen one like this before!

yer thats what i thought but on a vn radiator? haha never seen it

[coolvxss]

series 1 vn radiators havnt got one.

[vk_calais5.0]

sorry mis read-actually no filler neck sort of thing thats strange

[Emackulation]

series 1 vn radiators havnt got one.

Yep, was gunna mention that its not a trait of the later VN models but one of the earlier models.

[Not_An_Abba_Fan]

Not a VS, there are two radiators for the VN's, series 1 and series 2. One has a cap, the other has an external reservior like the EA-EF Fords. You can either get the reservior or get another radiator.

HAHAHAHA!!! You would think so, especially working at the award winning dealership.

Tuche!!!..

[Keesh]

well all i no is mine IS a series one and has the old vl style overflow and HAD a cap, the one i got now has no cap.. i just wanna work out if its ok to use with the old overflow system with this radiator or not..

its not something i normally come across at work seeing as how all we do is sell parts.. its not my job to have a full working knowledge of a 20 year old car..

and ahh thanks for helping me with my question airstrike! i wish all admins were as helpful as you.. i dont see how you can have a go at someone for needing help mate, obviously i dont no, which is why im asking.. if you no then maybe you can post something that will help me

[hakhawk]

i sell parts at work aswell, from all makes and models, i know that theres lots of things i dont know, but you sell holden parts, you should have a better knowledge of a 18yr old commodore than me.

anyway, theres no reason it shouldnt work, just look at the setup of a vn without cap and copy it. i reckon yours has been replaced with one with a cap before you got it, mines a 90 model and doesnt have the cap, same with my other 90 model wagon.

This is my problem!! You ask some stupid questions for someone who has to tell us he's a parts interperator for Holden every chance he gets. As much as i'm an admin, im also a member.

[Keesh]

so asking whether or not my radiators going to work is a stupid question? having a series one, i naturally thought that series one has a cap.. i cant look up the catalog at home can i? seeing as how we dont even sell vn radiators i think my question is a valid one. i dont mind people making jokes but u always find a way to make it personal.

ok so far i have a series one overflow with a series one radiator, but it obviously worked with a series 2 radiator (if thats what i had in the car)

[1vngal]

Well, like Troy said, seeing as though it's an '89 model, it would have had the series one radiator at some stage. So unless other things have changed dramatically, it should work just fine.

As long as your overflow bottle on the LEFT has a screw-on cap, and your overflow bottle on the RIGHT is the type with the pop-on cap, you can safely use a capless radiator.

The series 1 VNs without the radiator caps were a fully pressurised system, and this pressure flowed on to the first overflow bottle. In series 2s with the cap and only one bottle, the bottle wasn't perssurised, just the radiator.

Hope this helps.

Post us a piccy of your engine bay

[Shortstuff]

My March 1990 VN has a capless radiator and the older style resevoir (screw on cap) on it. Hozy made a thread on engine bays and there are loads of pics there. May help you? The radiator with the cap was apparently used on cars after november 1990 originally.

[calais_cruzin]

I had a 88 VN it haed a caped radiator, but it was involved in a front end smash b4 i got it, sooo it mite have been changed

[Keesh]

doesnt help haha.. mine has only one resevoir on the drivers side. i had a look on microcat and the early one looks like it has the one tank, and then the series 2 has 2 tanks? im not sure if it was acurate.. ill find a picture hang on a tick

[Keesh]

ok heres the setup that was runing.. one resevoir and a the capped radiator

[1vngal]

I'm fair sure thats the series one set-up. As your over flow bottle is a different shape to mine, and mine has a lid like the washer fluid bottle.

[Keesh]

well i no that the point of having the cap is so that it opens at the rated pressure to let the coolant back into the tank, now if this doesnt have a cap then how does it work? im guessing the overflow tank would be pressurised aswell then.. hence the screw on cap..
