This is why you should test your coolant.   When you froze the radiator, the coolant in the engine had nowhere to go. As a result, you overheated the engine. Since coolant wasn't circulating, the temperature at the sending unit was probably much lower than what was happening in the water jackets.   As for the knock, without hearing it in person, it's hard to say. You may have wasted a bearing (or several). You may have cracked the block, with all sorts of possible unpleasant results. Take it to a mechanic you trust and find out.
#2185 of 3244 Do 04 GMs ride any better than 03s? by ragdollgirl Feb 06, 2004 (9:23 am)
Just wondering if anybody knows whether the 04 GMs have a better ride than the 03s. My 94 GM is great, but it has over 183k miles on it and I am starting to look for a new car. May not get a GM, though, if the ride hasn't improved. Any thoughts?
#2186 of 3244 04 GM ride by james130 Feb 06, 2004 (1:31 pm)
I too would like to know if Ford have improved the ride for 04,ragdollgirl.Hope someone has experience of the latest model,and can answer your question.By the way did anyone find out if Ford have released any new softer shocks for the 03s?
#2187 of 3244 Re: shock changes on '03 and '04 -- by harmar Feb 10, 2004 (1:00 am)
See posts # 2125 and 2135. Reason(s) unknown, but there was, according to those posts, to be a new shock issued in Dec. for '03 models. Details were uncertain. If Ford saw fit to issue a different shock for retrofitting the '03s, perhaps the message got through about buyer dissatisfaction? If so, the '04s would likely have the new shock. Lots of "ifs" there, but parts managers ought to know. If the Dec. shock has a new part number, then ask what the difference is between that and the '03 standard issue. Softer ride? Some investigative work is in order for interested parties. Good luck.
#2188 of 3244 Thank you harmar by james130 Feb 12, 2004 (1:48 pm)
I will try to make a few enquiries.If I do find out any "good news",it will be my pleasure to post a message.I am sure alot of owners would welcome softer shocks.
#2189 of 3244 94 CV Question by jrc346 Feb 12, 2004 (3:42 pm)
I have been reading through these posts and noticed that many of you have 94 Crown Vics or GM's. I am about to dive into a ERG port cleaning on a friends 94 CV with ~117,000K on it because the check engine light is on, along with a poor idle while in gear. While I have seen this is a common problem with 93&94 Panthers, I want to make sure I am not doing something for nothing. I just wanted to take a quick poll and see if any of you 93 or 94 CV/GM owners had to have your EGR ports cleaned, and if you did, what were the symptoms that caused you to clean them? Thanks I really appreciate any responces any of you might have.
#2190 of 3244 re:egr cleaning by vidtech Feb 12, 2004 (4:31 pm)
generally dirty egr ports will not roughen the idle unless the valve is stuck open a bit.when the ports plug up usually you will experience pinging and the NOX readings will be high during an emmission test.to test if the ports need cleaning i would disconnect the vacuum line running to the egr and attach a long piece of vacuum line to the fitting on the valve.you can use a vacuum pump or suck on the line yourself.during IDLE while sucking on the vacumm line to open the valve,the engine idle should roughen a lot or stall if the ports are clear and the valve is working.if nothing happens the ports are either clogged of the valve is defective and not opening.
#2191 of 3244 Re: Vidtec by jrc346 Feb 12, 2004 (6:04 pm)
Thank you for your thoughts. You may have saved me some time. I saw how I could test the EGR with a vacuum meter, but I don't have one, and I didn't want to buy one just for this car. So I like your method and will defiently give it a try. I wont have a chance to work on it until Saturday, but I will let you know what happends   Any other ideas or stories out there?   Thanks JRC
#2192 of 3244 Cleaning EGR Ports by dbc123 Feb 13, 2004 (7:18 am)
I agree with the comments by vidtech. You can pretty much be assured that the egr ports are restricted if the car has over 100K and they have never been cleaned. Most seem to go 110-140K before becoming so clogged that the check engine light comes on. Cleaned my 94 at 120K and has been fine since (currently at 156K). Rough idle may be a different issue. Possibility: plug wires go bad at about this point and cause rough running. Also IABP valve could be faulty.
#2193 of 3244 '04 Crown Vic LX by samnoe Feb 19, 2004 (8:46 pm)
I just rented one for a few days, almost new (2,600 miles). I never tried the '94 so I can't comment on ride difference, but it was a very soft, smooth ride. However, It does NOT seem to be too different than 2003 models I've rented.   One thing I found missing in 2004 is the 'cornering lamps' (the lights which turn on whenever you signal). It was great in the 2003, and I missed it in the 2004 model.   Did somebody noticed it on their '04 cars? Any idea why Ford eliminated it?
