Title: rad replacement
Post by: Richie London on 22 February 2008, 12:40:50
can anyone tell me how hard or how easy it is to replace a rad. ive a pinhead crack on the hose connection just at the top, and its plastic too. i thought about trying that jb weld stuff but can get a rad from the breakers for 40 quid. mine is a cdx 2.5, 98 auto model.

thanks richie

That's where my radiator split as well.  I tried to patch it up with resin umpteen times and then took it to a radiator specialist to try and fix it.  Ended up having to replace it but it's very easy to do.

ive just put about  20 gallons of water through my system, took expasnion tank off and cleaned, couldnt believe the amount of crap came out of it. obviously never been cleaned in its history,  most of the hoses were very loose too. hopefully thats all thats wrong just the rad. it was losing all in the expansion tank then the temp was just leveling at about 90, unless i booted it or had heating on but soon dropped back down again when fan kicked in. probably needs a good service on the car.

I'd seal that crack up just now because it won't take long for it to get bigger.  Remember the system is pressurised.

Hi RichieRich.
Replacement of rad is about 2-3 hours work and is quite simple.It is worth getting new seals for the thermoswitches and you will also require a couple of new  washers for the power  steering pipes that go into the oil cooler.Hardest bit I found was resetting the radio codes after job as it is easier with the battery out.
Best of luck with it

Unfortunately the 'plastic side tank' top hose side, is prone to hair line cracks which leak under pressure, as yet I have not found anyone who has successfully repaired the split, changed my rad 4 weeks ago, not to difficult just a lack of space, I didn't remove the battery.

Neither did I.  :y
I'd be reticent about a 2nd hand rad. You don't know its history & might well have to do the job again. Although a new rad is about £200 on Trade Club you'll only have the job to do once.

A re-gass would only apply to the air con rad (the rad nearest the front of the car) I had to take out the first rad to get to the aircon rad to replace it.

You will just need to remove/replace the first one  :y

You shouldn't have any problems scourcing the rad you need, they are readily available

thanks for the info roland, much appreciated but do you know offhand how much just the rad is new.

On a similar theme,is it possible to replace just the cooling fan without removing the rad ?as I have noticed with "eco" on so only the main radiator fan running there is a grinding noise and suspect the bearings are giving up on the fan.
Expect the whole unit needs replacing as doubt if worth effort in stripping it down and trying to replace just bearings.Any body have idea of part number and cost?

Depends on where you buy from, if VX expect to pay a lot.  There are some new ones on  ebay for around £100.

wouldn't consider fitting a used one, do the job once and fit new  :y

Was intending to buy new or as close as,so will keep looking.Is it possible to remove and replace fan unit without takink entire rad out then?
Title: Re: rad replacement
Post by: RolandL on 22 February 2008, 22:59:19
Shouldn't be a problem, fan is secured in three places on the rad. Once trumpets are removed you will get better access to it  :y
Title: Re: rad replacement
Post by: amba on 22 February 2008, 23:02:30
that,s what i thought but couldn,t remember if one of the bolts securing the motor assembly was behind the edge of the rad and would be impossible to get with rad still fitted.Thanks for part number,have found something similar on fleabay,but part numbers differ.

If you are going to get it replaced which I strongly recommend, I'd try your local yellow pages.  I found a few places that repair and replace them.  As said before the guy couldn't fix it but a brand new radiator only cost me £100.
