New 310R Coolant Issue

[slowdude]

Did you ever find the source of your disappearing coolant?

[Randy Flowers]

No, I never did figure out why the coolant went down.  I added some distilled water and it never went down again.  We never saw any leaks.

 

I am selling the car now though for financial reasons.   About to put it onto Rocky Mountain's site.

I did the orange & green mix and the solidified sludge clogged up my water pump and head passages,  and maybe some radiator.  If I hadn't drained the coolant a year or two after parking it, Im sure the radiator would have been packed as well.

So I need to clean the engine and head out. 

 

I did a lot if reading on the Dex-Cool OAT subject.  Although I need to be a chemist to fully understand the sludge phenomena, there are some points I came away wirh:

OAT coolants are excellent coolants.  However, (1) you must not mix them with anything else but water and,(2) all the components and  materials the OAT contacts must be compatible with that coolant.  OAT will attack some silicone hose.

 

Most kit car builds will have a combination of manufacturers parts, Ford with BL, etc.  The coolant you choose needs to be safe for all the components involved.

If I suspect coolants have been mixed, what is the advice on effective flushing of the complete system?

 

A good flush is on my winter list.  The coolant is off color and cooling efficiency has not been good with this car.  So best to reset and start from a known place.
