Marauder overheating

[88LTDCV351]

I have 154,500 miles on my car. Car runs great. After about 100,000 miles, I started to flush the gold radiator fluid every three years at a Ford stealership. So today, I went to the stealership for my flush. I made sure to remind them that the car has to be burped and which they said they did. Car was fine when I took it in but they said that there was a blockage or bad thermostat when they finished. They looked it over and said it was a bad thermostat. They could get an aftermarket one by end of day but they would have to keep the car over the weekend since they are closing.

Several years ago, I bought a Motorad 7265-180 Failsafe Thermostat on Amazon. So I had them put this in the car.

They ran it for 30 minutes and said it was fine.

However, on the highway on the way home, the car started to overheat and get close to the red. I didn't want to take a chance of it getting in the red, so I pulled over and shut the car down. Called a tow truck.

Anyone have problems with these thermostats before? I'm going to order a Motorcraft one and limp the car to another stealership.

By the way, I saw another Marauder drive buy. A black one on the highway. I-580 heading west. Time was about 3:30.

[RubberCtyRauder]

May still need additional burping. I've heard that the thermostat can be placed in upside down thus making it not work or something like that

[fastblackmerc]

As mentioned they could have installed the stat the wrong way or still needs to be burped.

[88LTDCV351]

I had the flush done at this same stealership three years ago. He said they know how to burp it.

When they did the flush today they said that there was no heat in the lower coolant hose. That is when they first said that maybe the original t-stat was bad or there was a blockage. Then they said it was the T-stat. When they put the Motorad one in they said there was some heat felt in the lower hose. Obviously something still isn't right. They must have put it in backwards or not burped it enough as you all suggest. I'll go to the closer stealership and have them take a look at it next weekend. I'll bring a new Motorcraft T-stat from ebay in case its needed. It should arrive by then.

I was the one on the side of the road with my blinkers on. Was that you Brian who passed by on the highway? lol

If your MM was working fine before you took it in and it wasn't working fine when you left they probably don't know what they are doing regardless of what the service manager says. Taking it to a different place is probably the best way to go.:)

[bigmerc281]

I went with a 170 thermastat and proper burping havent had a over heating problem since

[88LTDCV351]

I tried to google the burping process but got some articles and youtube videos about doing it for Grand Marquis but no mention of the burping process (I don't think they have the same crossover tube setup). Anyone have a good link handy to share on the process?

[NavySeabee]

Here ya go...

[88LTDCV351]

I got an email back from the service manager. They say that the T-stat only goes in one way. Uh, I think they are wrong. Supposed to go in one way correctly but apparently there are some that will fit both ways by mistake, right?

[camelgrundle]

Yes you can put it in backwards

[babbage]

tstat goes in upside down, then install the gasket, then attach the lower hose. Also the Motorad 7265-180 is not the correct t-stat. It does not have the thermal bypass. Holes in center shaft. Get the motorcraft unit.

Edit: see here http://www.mercurymarauder.net/forums/showthread.php?t=97250

[RubberCtyRauder]

Motorad 7265-180 is their failsafe t stat..they dont offer a 180 for Marauder only 195 so it is a mach 1/cobra one for the 180..the 195 failsafe is 7265-195. so maybe the failsafe version is not right to use? however they offer it in the 195 for maraduer

[fastblackmerc]

Spend the coin and get a Reisch Performance 170 degree stat.

Which is not the correct tstat either. NONE of the Motorad units are.

Spring towards the engine, ie the hot fluid. That's all you have to remember when installing it. I found this out the hard way.

[Badass_forever]

if your t-stat does not have the by-pass holes, the t-stat will not heat up fast enough and the car still start to over heat. It needs the by-pass holes to allow the hot coolant to flow past it and heat it up.

[justbob]

If you squeeze every single coolant hose in the engine bay multiple times while your filling it up with the engine off then you should be fine to cap it and drive.

This is all I've done the last couple of years on multiple MM's and never once an issue.

I'm not sure if the Motorad is the right one or not. I just remember someone pointed me to that one when I was trying to buy more parts to complete my supercharger kit that DR shafted me on.

I took it to Big O Tires and they said they were able to burp more air out of it. They said they had to add more coolant because so much air was still in there. They said it isn't overheating anymore so they didn't think it needed another thermostat. I'll try driving it around when I get it back and see if its having anymore problems. The new motorcraft one did arrive this week in the mail if I have to have it replaced again.

[Badass_forever]

the marauder overflow bottles are "de-gas" style overflows, that means you should never have to berp the cooling system. I have always done it because im old school. but I did it once in front of a new school guy. He looked at me like i was an idiot.

Not "old school"....... it's "NEW SCHOOL"

It's a proven fact that you DO need to BURP the cooling system. Change the stat or hose and try driving without burping......

Correct info here!

[88LTDCV351]

Got the car back from Big O. Drove it for about 45 minutes sometimes spirited and even took it for a stint on the highway. So far no overheating. Seems normal. I'll keep an eye on it.

[babbage]

I'm not sure if the Motorad is the right one or not.

I'm sure none of the Motorad are correct for a Marauder
Glad you got the air out of it.

Put the motorcraft unit in when you get a chance - have the 2nd shop do it that got the air out.

good luck.

[Badass_forever]

A degas tank is part of the pressurized cooling circuit and is designed to allow air bubbles to be forced up and out of the cooling circuit. Some include a pressure cap and serve as a fill point as well. Not all engines utilize a degas tank.

Right from the ford manual at work.

[RubberCtyRauder]

Have not seen a marauder yet that did not need burping if system was opened, etc

[Badass_forever]

I agree, I had to berp my 4v as well.

[NavySeabee]

Mine overheated on 2 separate occasions right after getting out of the shop, they didn't know either. All was fine after burping.

[88LTDCV351]

Was getting gas this morning and noticed the temp gauge went higher than I felt comfortable when I was going over the bridge on the way to Costco. But after I got gas and drove to my brother's apartment, the car was normal temperature again until I got home. Everything is closing right now so I took it to a place that is open on Sunday. I asked them to put another thermostat in there but they said they have to diagnose it first. I'll hear back from them tomorrow.

[babbage]

Step 1 - get correct t-stat. Scroll up! I'll bet dollars to donuts that the shop puts in a wrong t-stat yet again. I'm loosing count is this the 3rd or 4th time you brought to shop?

Sounds like you may be paying for " $Sunday Labor$" also. Good luck.

I looked the t-stat at work, went and grabbed it off the shelf, its not the right one. its looks right and fits right, but does not have a by-pass passage.

someone posted the right part number before, the thermostat needs to have a vent hole in it.

When I look at Rock Auto and thier photos for the Mustang Mach 1 and the Marauder, same thermostat part numbers in almost all cases but Mach 1 has more thermostat options listed. Looking at the photos, some have the vent holes and some not.

Just buy this one and be done with it.

They wouldn't install my provided Motorcraft part. They insisted on doing the diagnostic and block test, etc. and they would only use thier own parts. They couldn't find anything wrong with it and couldn't get the car to overheat so they didn't charge me anything.

However, just tonight the car's temp gauge started to go up again on my way back from Walmart. And then it went down as I watched it. These Motorad thermostats are junk. Looks like it doesn't open and close all the time properly. The closer stealership only does oil changes on Saturday so I'll have to figure out how to take it there during the week but I work a far distance away so its hard to drop off and get the car back when they finish.

I think Reische Performance website description might hit on it here: http://www.lethalperformance.com/reische-performance-ford-4d-170-performance-thermostat.html

"Beware of aftermarket companies who sell the same thermostat for all Ford modular engines. Those units are designed for the 2V SOHC engine and, if installed in the improper housing, will be unable to shut off the bypass- allowing hot coolant to recirculate back into the engine at all times, reducing the efficiency of your cooling system.
Our thermostats are custom made with the same size diaphragm and bypass control as the OEM units. "

[RF Overlord]

Replacing the thermostat is dead simple...just do it yourself.

Have you done any of the things we asked you to do? I cannot believe you are still having this problem. My car is still in storage or I would make you a video on how to trouble shoot all these problems. Maybe I'll head out to the barn tomorrow.

I can't do the work myself since I live in an apartment complex. They frown on any auto work on the property.

My sister stopped letting me do oil changes in front of her house after the cops told me the neighbors didn't like us doing it in public view and the cop was afraid we would just dump the used oil down the sewer. My sister is afraid I'll dirty up her garage also. I did manage to put a new radiator in my 88 Crown Vic before anyone said anything but that was several years ago. Now new houses have sprung up there everywhere so not sure where I could do it without cars and people all around staring and pointing.

I have no experience burping these closed systems but I would try it if I had a garage.

And I've been busy working so I haven't had much time to take the car for repair. I have to leave home early to be in traffic for about an hour and then by the time I get back the shops are all closed. So its difficult to drop off and pick my car up when they are done repairing it. We are also very busy at work right now preparing for our company split (we are becoming two companies so we have to create processes and policies, etc. for both companies in addition to our regular job). And my girlfriend has kept me busy on the weekends.

They pretty much wasted everyone's time because they didn't put a new thermostat in there for me or anything. I just did a bunch of tests and couldn't get the car to overheat. They were actually pretty rude when I tried to explain everything to them (like they know better than me) so I felt weird about leaving it there. Well, at least they were nice about not charging me anything but more of my time was wasted. My girlfriend was not happy about me having to leave her birthday activities to take care of this car and they didn't even do anything to it, at the end of the day.

I ordered one of these. Hopefully it will arrive soon so I'm not too much longer without a car.

I just cant believe a garage is not able to fix this. unless you have an under lying problem "i cant seeing that being possible" everything that needs to be done can be done in under an hour.

Dropped the car off at Big O Tires this morning. They are going to put the Motorcraft thermostat in today.

The Lethal Performance T-stat hasn't even shipped yet but I wanted to get my car back on the road so maybe that will be for another time.

[Badass_forever]

let us know what they say.

[88LTDCV351]

Got the car back. Drove the 25 miles to work (an hour in rush hour traffic) and no overheating. Usually takes longer to get home so that will be an even better test later today.

Holy crap! What communist country do u live in?!?!?

Screw the apt complex, as long as you aren't rebuilding engines & tying up the lot for days (which is understandable on their part) do what you need to do. A couple hours working out there and leaving no mess is perfectly acceptable.

Screw the neighbors and as for the cops, they have to prove it. As long as you are responsible and DON'T dump in storm drain - you are good.

Good luck with repairs.

[88LTDCV351]

Last time I replaced the spark plugs (maybe a year or so ago), I noticed one plug (the last rear one on driver side) was very tight for the spark plug. Does that mean that the stealership may have rethreaded that one? Last time I think the plugs were replaced previously was with the cylinder head that the Stealership replaced (back in 2012).
