I also have the problem with the loss of power after about 20 miles. I have taken it to a few garages, and they all seem stumped. Does anyone have a clue what could cause this? So far, the garages have changed the plugs, leads, fuel filter and coil pack. Changing the coil pack seemed to fix it for about a week, but then it reappeared.

I was commenting on the loss of power though not the coolant loss, the same problem as the majority of st24 owners seem to have, and as it seems to happen after the engine gets hot, I'd have a guess at it being the engine sucking in warm air, chav cold air feed LOL

Wow cheers dave, sounds just like the problem with my car, if you or some one could send a link to a page where I could order these medium power darlington transistors from or box, then that would be great, P. S I know the previous comment is old so I'm hoping someone is still out there looking at these links.

I have a ford mondeo 2.5 ghia x the catch on the glove compartment has broke and I can't open it, can anyone help and tell me how to open it thanks.

The catches for the glove box are at the top on both sides; just jimmy them with a screwdriver.

Hi I hope you can help me. I own a mondeo st24 2.5 v6, the car accelerates fine but when I remove my foot from the accelerator, instead of slowing down smoothly it shudders and jerks but does not do it all of the time normally once warm. I have had it looked at and the garage said first it was the condenser and then the imrc I think. Both of which were replaced but have not solved the problem. They have now said its possibly the EGR valve but I don't want to keep spending on the wrong things. Can you help.
Thanks a lot.

Hi I have a 97 ST24 and don't know where the fuel filters are.
Can someone help please?
23rd Jul 2008, 02:18
There is just the one fuel filter from what I can remember owning mine.
If you look under the sill underneath the rear drivers side door you will see it tucked away a bit behind the sill with two fuel pipes either side.

Thanks a lot for that Ben, will have a look and see if it solves the problem.

You know the thing that opens when ya hit 3500rpm, to allow 24v instead of 18v being used? Can this be jammed open if you wish?
23rd Sep 2008, 03:34
Yes it can.
But it won't run very well, if at all, due to the setup of the engine. If you can keep it running however, 6.5 seconds is on the cards to 60!
The two small pipes on the upper inlet manifold are what create the vacuum to hold the 6 valves closed. Remove these carefully without breaking the plastic holding clips and you've got a permanent badly running 24v!
Discovered this by accident when changing the plugs on a mark 1! It was very quick though but got about 16mpg!

I own an ST24 and it is a dream - the loss of power problem is caused by the IMRC overheating - the IMRC is the little part of the engine that opens up the secondaries at 3.5k revs. When hot or humid, the chip inside doesn't function properly, leading to the secondaries staying closed. A simple fix is to relocate it, and it takes literally 30 minutes to do, and about £2.50 worth of supplies.

Hi, I've just bought a 2.5 V6 Ghia X on a 52 plate, it;s got the same ST24 engine. The car won't rev past 3000rpm in gear or 5000rpm when not in gear. I tried using injector cleaner and spraying it down the air flow pipe directly on to the air valve, it seems to jam?? If I floor it in 5th gear when am doing 60mph, it splutters and dies. If I put it down a gear, it slows down then stalls. So I have to drive everywhere on egg shells doing under the speed limit. Gutter. Anyone help please?
