If you get a series 2 PTU, does it fit without any special brackets. Is it just a case of bolting it on and using your existing wiring?

Hi John,

 

You'll need the adapter wiring but I can't see why you can't do with out the bracker :)

Thanks Vijay,

 

I was curious, I saw one on Ebay, no wiring or bracket though.

My series 2 from Courtesy came with everything to do a straight swap.

 

Yes, I just checked Courtesy site, $180, comes with wiring, screws, bracket, etc.

 

The one on Ebay comes with nothing, but only £50 so far.

I acquired a a 2nd hand one but it didn't have the bracket. I just need to knock one up out of a bit of steel/ally when I have some spare time - shouldn't be difficult.

or do as i did and fit a 12v dc fan about 5 cm away from the series 1 PTU i have never had a problem with it overheating

Sounds like a good idea :cool: , is it the heat that causes the failure then?

 

I wonder if most peoples PTU failures have been in the summer ?

After thinking about the fan idea, surely the amount of air from a 12v dc fan is nothing compared to what it gets while the car is moving ? (is it only effective when standing still?)

 

John

the fan came in a shroud which fitted nicely nearly covering the PTU its jmakes just enough air to move accross the heat sink fins of the PTU to disapate the heat which is nearly all radiated heat caused by the water pipe that runs just to the underside of it

 

there is very little air moving in that part of the engine bay when the car is moving as most is diverted through the radiator and away from that area of the engine hence the static heat build up from water pipes etc etc can not escape very well

 

got my fan from RS components about 5 quid and an hour wiring it in on Sunday

Is it an 80mm or 60mm fan ?

Or you could just re-locate it.

 

 

Do you know if that has been done? Is there enough slack in the wiring?

 

John

I'm just about to and Stu (smw) did the other week. There is plenty of slack.

Let me find a pic of Stu's for you......

Great! :hyper:

 

Thanks

Hi John,

 

There is plenty of wire once you remove the outer sleeving. I relocated mine to near the air filter.

It's a good idea and I'm sure it helps, but having seen the inside of the PTU's I can help thinking that vibration must play a part in the failure too.

Andy,

 

Is there any way to reduce the vibration ?

 

Thanks

John, are you getting or do you have already a series 2 ptu? I have read a few times that these never fail!

James, no, mines a series 1.

But when I bought the car last year included in the documents were several receipts, one was for a new PTU that was installed in April 2002 (and it looks shiny and new'ish)

So I am just trying to prolong its life, its only 2 years old.
