1998 V6 Radiator Part Number

[dipsomaniac]

no part number on the rad - has anyone got a part number. there is one on ebay at the moment with the part no 7M3121253A. it says it fits the AYL engine. i don't know what engine i have. V5 starts VCO.

Hi Dypso.....,

The AYL engine is the 24 valve version of the VW V6. You have most likely the AAA engine which I have. This is the 8 valved VW V6 version.I'm afraid I can't help any further with the radiator however,all you can do is visit your local parts dept and compare the diagrams for each engine's radiator,failing anyone else having the definitive answer.

Cheers,

Steve S.

The radiator for the mk1 AAA engine is very similar to the radiator for the mk2 AYL engine.

 

However there is a slight difference in size and hence it would not fit.

 

 

 

You definitely need the MK1 radiator, and yes it has to be from a V6, the other mk1's are different also.

found a new one at radiatorsonline - 55.85 + 10 delivery + vat. 2/3 of the price anywhere else was quoting - even ebay.

radiator delivered this week and began fitting yesterday. autodata are quoting 1.7 hours - i have been working on it for about 5 hours sofar. without discharging air con it was a nightmare trying to fit condenser onto radiator in situ. it is attached by four bolts, 3 are reasonable easy to access and fit, the fourth took me about an hour and i lost half the skin on my fingers.

 

just filled with coolant, radiator is ok but have a leak from the cooling fan switch on the rad and it looks like the bottom hose might be leaking but hard to tell until i have fixed switch.

 

anyone know what i can use to stop leak on the switch. i was thinking of plumbers mate or ptfe? or can i just tighten a little more (if i have a spanner big enough). there was no sealant on the switch when i took it out of the old rad.

 

should i also have replaced the spring hose clips with jubilee clips? if the bottom hose is leaking that is the only thing i can think of doing.

[seatkid]

Would have thought there was an o ring on the switch/radiator or a rubber washer.

 

IMO spring clips are usually very good and v difficult to damage. Could the leak from the switch be dribbling on the hose?

thanks seatkid. will look again at old rad to see if i have left off an o ring or washer. just hope i can get to it ok as i don't want to remove rad again. it is hard to tell if bottom hose is ok until i fix switch.

 

when i popped out again earlier this evening it didn't appear to be leaking. i am just hoping that the parts might have been bedding in as i ran the car until fans kicked in and let it cool.

there should be seal on the switch on the radiator,if there was get a new one,if there wasnt use some sealing compound

[dipsomaniac]

have you got a part no. for seal/washer/o ring

[mk2vr6]

no,i just know the manual says that there should be a sealing washer or if not to use a sealent,you could try looking at the online etka site to see if they list one?

[dipsomaniac]

the online version of etka doesn't even show the cooling fan switch. is there a full version? the switch is screwed into radiator between top and bottom hoses.

[dipsomaniac]

does anyone know what size spanner fits on the cooling fan switch as i need to buy one? i can't get to it with an adjustable.

[dipsomaniac]

FYI. spanner size is 29mm for cooling fan switch. you need a combination spanner as you can't access with anything else. just my luck, after finally finding a spanner shop that sells 29mm combination spanners the price was 12.57. a 28mm is 4.99 and a 30mm 7.99 - don't know why?

 

the switch does not have a washer - i used a little boss white and it has now sealed ok. can't see how it can do any harm as it is only on the thread.
