Hello guys;

Just wanted to post this so highlight the importance of the facelift under-tray. I am going to mention a lot of different points so please bear with me:

Let me start by saying that I had my radiator removed less than two years ago. I had it flushed out and cleaned.

Recently I had noticed that my A/C was getting too warm at idle. It always is a little warmer at idle than at speed (although all the components are new) but it was actually getting uncomfortable. I the noticed my gauge was going past N-which it has not done in a long time.

My first thought was that the gauge was probably broken and that some freon had escaped thru the port. I bought a can of freon and was ready to get my gauges, when it occurred to me to look under the car--the bottom of the radiator was COATED in road grime. I removed the grill and sprayed a full can of engine degreaser thru the openings all over the condenser and the radiator as much as I could, then went to a car wash and tried the high pressure hose wherever I could reach.

After that I was in rush hour traffic thru a construction site in 95 degree weather and not only did the AC keep me cool, but also the gauge never went above N.

This is from a weekend type car that does not see the road more than 3
Days a week. And then it's typically to work, 5 miles down the road. No rain. I think that if the undertray would have been in place my radiator would not look like it did.

 

the word "tray" is throwing my off. Are you talking about the plastic underneath or the front dam/spoiler

 

Hello;

Here is a the part (take from jaguarclassicparts.com) its number 12. As we have been discussing in other posts, it appears that the part will be available again soon, but I got lucky (or ripped of depending on how much the part will cost once back in production) and got a new-old-stock part from someone in New York. Reason I did not wait for the part to be produced again is because I remember Jaguar promising they would make the power steering reservoirs for our cars available again. That never materialized.

 

Good info Mark. I have always had the tray in place but I will check the underside of radiator etc. and will let you know how mine looks with the tray on it. i suspect you are correct that the tray keeps this area much cleaner.

 

There is a natural high pressure area under the car. If the undertray behind the spoiler is missing, it will have the effect of pushing air upwards to the rad stack. This will be caused both by pressure and turbulence created at the back edge of the spoiler if the tray is absent.

So, I believe, no tray will definitely have the effect of blowing rubbish from the road and airflow into the rad stack.

I haven't had mine on since I owned my car lol. I don't remember why it even came off or where the bolts are for it. I just see it in my garage sometimes and think, wtf is that thing??

maybe i will throw it on and see if anything reads different. Probably depends on where you live. I have been in and around my radiator, and even had it out, since owning it, and I have never noticed it being unusually dirty.

 

Hi all.... I've been sorta following the posts on this subject for awhile, but I have yet to find where to get one. Or if they are even available. No luck at any local breakers (i'm in Central Florida US)

Anyone know where to find one?
Anyone have one for sale?

Thanks in advance

I'd say keep an eye on on parts cars on craigslist and ebay which is pretty common, and just have it shipped.
