JA: So many things can cause water pump issues. Some simple, some complicated. Fortunately, the mechanics we work with have tons of experience dealing with them. Are you hoping to fix this yourself?
Customer: already told you not water pump as new one has been fitted
JA: Is there anything else important you think the Ford Mechanic should know about your Ford?
Customer: not that i can think of
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Ford Mechanic about your situation and then connect you two.

Hello and welcome. My name is ***** ***** I will be happy to assist you today. *** A BAD RATING HAS NOTHING TO DO WITH ANY DEPOSIT YOU MADE ***** .Let me start by saying that any money that you paid, or if you have a subscription, that money stays in your account until the answers are rated, (positive) regardless of how fast or how long it may take to get finished. You can FOLLOW UP AT ANYTIME, even after rating..They are sometimes bad about the radiators clogging up and causing an overheating. You can have that tested at a radiator shop or feel around the core when the engine is hot to see if there are any cool spots that would indicate a clog..However, with any engine that runs hot, overheats or has been overheated it is best to check the integrity of the engine, (head gaskets and heads, etc.). The first thing that you want to do is check the cooling system for any exhaust gases. Make sure that it’s full first. There is a tester for that, that you can get from Autozone for about $20. They will normally lend you the tester and you just buy the fluid for about $8. It comes with instructions, but there is a blue fluid that is used in it, if the fluid turns yellow, that is exhaust gases. . Block tester available is: Napa BK.(###) ###-#### ***** Tester AUTOZONE Part Number:27145 http://www.autozone.com/autozone/accessories/Tools/Block-Tester/_/N-25dh?filterByKeyWord=block+tester&fromString=search .*****You will want to check it at different RPM’s and at different temperatures*** ... If there are any exhaust gases in the cooling system, that will cause more pressure than desired and will allow the engine to burn coolant and/or heat the coolant up too high. Most times not filling the crankcase with coolant either and not smoke out the exhaust. If there are, then there would be an internal engine problem, like a head gasket or head. .Please don’t forget to rate the answer, **** THAT IS THE ONLY WAY I GET PAID **** if you need any more on it, I will be here..

no sorry
Expert:  Master Auto Tech. replied 8 months ago.
Hhmm it will make it a bit harder then.
May I ask, from your description I take it that it cools fine at idle and slow speeds but high speed it overheats? Is that correct?
Customer: replied 8 months ago.
THATS CORRECT
Expert:  Master Auto Tech. replied 8 months ago.
was this the original problem that you replaced all those parts for? The (radiator, fan, CTS, & water pump).Also Was the t-stat replaced? I don't see it listed.
Customer: replied 8 months ago.
T\STAT REPLACED ORIGINAL PROBLEM WAS GAUGE SAY IT WAS OVER HEATING GOING ITO THE RED
Expert:  Master Auto Tech. replied 8 months ago.
the original problem was it was overheating all the time? Idle and driving? Or just at high speeds?
Customer: replied 8 months ago.
JUST AT HIGH SPEED TEMP GOES UP VERY QUICK WHEN YOU GO OVER 65-70 AND COMES DOWN QUICK WHEN YOU SLOW DOWN TO AROUND 55
Expert:  Master Auto Tech. replied 8 months ago.
it's better now that you replaced those things but still not good or great?
So to be honest with you, I have only seen this 2 times in my 20 some years as a mechanic. And both times it was caused by a restricted radiator. At higher speeds the radiator wasn't able to cool the water enough becouse it was flowing to fast thru the few lines it had. I could put water thru it with a hose and it flowed just fine but some of the passages were blocked. I know you said you put a new one in, but it may be possible that if it's an aftermarket radiator that they skimped on making it and didn't put as many passages or as big of ones in it. Is it possible to get a double core radiator there?Also how was the coolant that came out originally?Thanks
Sonny
Customer: replied 8 months ago.
RADIATOR SEEMS TO BE THE SAME AS THE ONE THAT CAME OUT AND COOLANT THAT CAME OUT WAS FINE
Expert:  Master Auto Tech. replied 8 months ago.
Did this just all of a sudden start happening or was there other signs that led up to this original problem?
Expert:  Master Auto Tech. replied 8 months ago.
Do you still need help with this problem?Thanks
Sonny
Customer: replied 8 months ago.
no thanks it seems that nobody knows what's wrong not even fords going to try replacing gauges now see if that helps
Expert:  Master Auto Tech. replied 8 months ago.
I doubt that's the problem. But can you let me know what happens when they do? And in the mean time I'll do more research.Is that ok?Thanks
Sonny
Customer: replied 8 months ago.
seems that the problem was an air lock to do with the EGR valve
Expert:  Master Auto Tech. replied 8 months ago.
That's odd but I'm glad it's fixed for you. Thanks for telling me.
