Title: Engine undershield - To be or not to be
Post by st.eve on Dec 16^th, 2009, 7:23pm

I have a 1996 Scorpio Ultima 2.9 auto.

Can anyone please confirm if the car should have an engine undershied. Mine doesn't have one and it seems to hate me going through puddles.

If it should have one, does anyone know if they are still available.

Many thanks

They all had them originally,some people leave them off for better accessibility to the steering gear,then I suppose they just get dumped.
There should be plenty of used ones about,Highlander gave me a couple to replace mine that were missing,I've had a couple of breakers since,there could be a spare one here,condition unknown !! Where are you ?

SNAP Stuart ;)

I appreciate your speedy reply.

I'll give Ford a call for a price. Seems easier than trudling round a breakers in this weather.

Many thanks

I had two on my Cosworth for a while.... the one under the engine and the one under the cats!!

Well I've had the car a couple of years now but whenever I go through a lot of standing water, it screeches at me (probably water on the alternator belt causing it to slip momentarily), the lights all dim down, I get a loss of power, the heater fans slow down and if I have to come to a halt shortly after, the engine sometimes cuts out too, so I figure it's probably down to the missing engine under shield tray.

In addition, my electrical gremlins have just returned, exactly as in February of this year... http://www.fordscorpio.co.uk/cgi-bin/yabb/YaBB.pl?board=Problems;action=display;num=1233745033;start=
(Except the engine fans aren't causing a problem this time, just the dashboard lights staying on when ignition switched off), so just trying to take precautions and weatherproof the car a bit.

Sounds more like a problem with the belt/tensioner if the heater fan slows because the belt is slipping then your battery isn't very well charged.

I don't have an undertray on my 2.3 when the belt screeched in the past it was due to a stiff tensioner. It doesn't screech since freeing off the tensioner.

Yep you may well be right, I'll take a look. Although only happens when I go through puddles and everything seems to get soaked. Sometimes the engine will cut out and I have to pull the leads off the coil to dry them out, that's why I initially asked about the undertray.

One distinct advantage of the engine undertray is that the engine doesn't get a soaking when going through puddles.....there are a couple of parts of the engine loom that go low down to the the crankshaft sensor & oil pressure sensor. It also stops the engine getting caked in road grime & bits of any animal that should happen to wander out in front of you....makes it easier to pinpoint oil leaks ;)

......& the front of it slots nicely under the front bumper, so it protects the bottom of the rad & pipes etc from corroding before their time :)

well I guess Fords price will be an arm and a leg job but I'll see how I get on tomorrow. I still have to try to get to the bottom of the electric gremlins, the fuse boxes are all dry, no crud around them, drain holes are all clear so not sure right now where the problem is.

Mine hasn't got an undershield, and I have just had to replace my alternator through puddles, will have to look out for one.

Title: Re: Engine undershield - To be or not to be
Post by st.eve on Dec 17^th, 2009, 10:39am

Well Ford's price on the undershield is £159 (including the obligatory VAT) so I'll try a few local breakers but will leave it till after the hols. Right now I'm more into sorting my electrical gremlins.... dashboard lights staying on when the ignition is switched off. Bit of a mystery where to begin 'cause like I said, the fuse boxes are both dry, drain holes are all clear so not sure if it's an ingress of water somewhere or just the cold damp weather (scratches head) :-/

Cigar lighter socket?? in ashtray sometimes it will short out causing odd faults ?

Title: Re: Engine undershield - To be or not to be

I'm pretty sure it's fuse box related (drivers side).

Last time it happened back in february, when all else failed, I went at it with a hair dryer a few times and eventually the fault went away. However, at that time there was crud round the fusebox, since then I've kept in clear.

A couple of links relating to the variety of faults that can be caused by an ashtray problem.

Just thought I'd give you an update on my electrical gremlins in the hope that it might be useful to others if anyone experiences the same problem.

When the main loom that runs along the nearside (beneath the coil) was moved about, the problem came and went. Upon further inspection, it was found that the insulation on several of the wires had become very brittle and was causing shorts, thereby turning on the ignition light, oil warning light, engine fans etc with the ignition turned off and the key removed.

Some sections of wire were replaced and the whole lot well insulated again. For now, this has resolved the problem. I guess the loom could do with replacing but no doubt this would be a very expensive option.

Happy motoring

Hi Gozz. After reading the thread I have noticed that I do not have the undershield on my '95 Ultima. Should it have one and did I read right that you may have a spare available? Lee

St.eve, no need to trudge around breaker yards, just go to <www.breakeryard.com> tell them what you are looking for and then sit back and wait for an email.

St.eve are you still having these problems?
I might shed some light though you may not like it.
Let me know.
