Changing Coolants?
 

My FEH is approaching the 6 year interval for changing engine coolant and motor/electronics coolant.

My usual dysfunctional Ford dealership wants $160 to change the engine coolant, and says they don't recommend routinely changing the M/E coolant. Owner's manual says to change both.

Has anyone changed both systems and is it a DIY type of service? Would I need to flush the systems or just replace coolant? And what do you think about only changing the engine coolant?

Thanks

I have done both the engine and the m/e coolant in both of mine. Pretty straight forward job. Hardest part is getting the plastic shrouds off underneath the car so you can access everything. There is also the bleed valve that needs to be opened to get air out of the m/e system.

I have the pdf file that gives the step-by-step procedure. PM your email address to me and I will email you the file. It really is an easy procedure. Maybe 1.5 hours the first time. Much easier the second time.

Thanks Ray. Probably the same plastic shrouds that I removed for the MECS pump replacement. PM sent.

Other than the owner's manual, is there really a reason to change it? It's a sealed system and if the coolant is looking good, why change it? Odds are, you'll have a different reason to change that fluid at some point anyway right? Replacing hoses, Maybe a MECS pump replacement or a thermostat?

One piece of advice that was recommended to me by a mechanic friend years ago has saved me a lot of grief over the years. You may already do this... Always use distilled water in your cooling system (unless you're going with 100% antifreeze that is)! Manuals will recommend this, but few people actually do it.

You know that crusty stuff that forms in your radiator and the discoloration and sediment that shows up in your coolant over a period of years? You'll never see that gunk and/or sediment in a system that has been filled with pure distilled water for the 50/50 mix.

My main reason for changing at the specified six year interval is to maintain the hybrid warranty in effect. If I ever had to rely on that warranty in the future, I'd like to have evidence of coolant change at the interval in the service manual.

I've already replaced the MECS pump but no coolant was lost so I didn't change it.

The pH of the coolant changes over time as it degrades, and there are test strips like these for checking but they reportedly won't work with the Motorcraft Gold coolant.

Good call Don... I lost all hope in any warrantee ideas a while ago. My 05 is too old and has too many miles on it at this point.

Re: Changing Coolants?
 

I signed up on this forum and I think I might need to change this coolant. Could you please send me that pdf file?

Re: Changing Coolants?
 

I could use this PDF file also. THANKS!! PM sent.

Re: Changing Coolants?
 

also looking to do the procedure please send the pdf as to where the bleed valve is
thanks

Re: Changing Coolants?
 

Has anyone tried these coolant test strips? Supposedly measure the pH and tell you if the coolant needs to be replaced: http://smile.amazon.com/gp/product/B...=ATVPDKIKX0DER

Re: Changing Coolants?
 

Seriuosly, just change your coolant. If yours is yellow, buy some Zerex G-05 (NAPA, Amazon.com) and a few gallons of distilled water.

Hey folks,

Sorry I dropped off the face of the earth for a while. Both my '05 and '06 are still running strong with no problems so there isn't much to talk about on here.

I still have the pdf files if anyone needs them - send your email address to my inbox and I will send them to you.

Hope all you old-time owners are doing well.

Ray

Just new to the forum. Trying to find instructions on how to flush both coolant compartments for a Ford Escape Hybrid 2008 with 107,000 miles. The previous owner took the vehicle to the dealer for all maintenance schedules but they could not find out if the coolant was ever changed. Thank you.

Re: Changing Coolants?
 

Changing coolant is not a big deal. Note that after the initial coolant change interval the interval is shorter. Three years I think.When you do the MECS coolant be careful with the vent plug on the transaxle. it doesn't take a lot of torque to tighten it down properly.

Re: Changing Coolants?
 

Thanks for the instructions. Does anybody has the step by step pdf file that I saw earlier in the beginning of the forum? Thank you.

Re: Changing Coolants?
 

I too would greatly appreciate it if someone can PM me a copy! Thanks so much!

Re: Changing Coolants?
 

I would like the pdf on changing coolants in escape

Re: Changing Coolants?
 

If anyone is still active, I would really appreciate the pdf on how to change the coolant for the engine and the electronics!
Thanks in advance.

Re: Changing Coolants?
 

PM me your email address and I'll send you the pdf. For some reason I cannot attach it to a post.

Re: Changing Coolants?
 

Did you ever get anything on where the bleeder valve is?

Re: Changing Coolants?
 

Does anyone know if there is an engine block drain for the coolant? I want to get all the coolant out of the engine too, rather than just out of the radiator, but I'm not sure where it is. Does anyone know or have pics/PDFs that show where it's at?
I have a 2005 FEH

Re: Changing Coolants?
 

I have the same question. If you find out anything please let me know.
Thank you

Re: Changing Coolants?
 

I still haven't heard anything, but I'll let you know if I do and please let me know as well it you find anything!
