Zetec And Electric Water Pump Still Overcooling

13 September 2017 - 05:33 PM

new Spec 2.0L zetec with 243bhp

         55mm coolex polo derived rad

         raceline water rail

         davis craig ewp 115 electric pump and controller

 

old spec as above except standard zetec mechanical pump and 82deg thermostat

 

In the old spec the car would take for ever to warm up to the 82deg sat on the drive idling, if you pulled away before getting to temp it could take 15miles to get to 80 and if you were on a long steady run the temp would drop to just below 80deg, i want it to be 85deg. getting stats to fit, in the right temp is getting awkard as they are old ford xflow fitment so i thought i would try something different

 

i have now fitted the new ewp pump and controller, and the problem is worse!! the cars warms up at idle a lot quicker, it sits there holding temp perfectly with the fan and pump doing what they should.

I go for a drive and boom the temp drops from 90 to 75 and will not raise until i stop driving then it creeps up to set point and maintains it. 

 

This car used to have an old polo type rad which used to maintain the temps just but was always marginal when you started to raise the pace it would heat up and barely keep things cool, hence the change to the coolex 55mm, 

 

Does the rad have to large a volume and too large a surface area? every time the pump pulses, is it shooting a large volume of cold water round the system which is to much for the engine heat produced? 

 

Is the pump sending to much water round the system? both mech and elec pump did the same effectively. only difference is the mech had a stat the elec dosent its meant to be controlled electronically. 

Is the raceline water rail causing some sort of issue? 

 

Is the fact that car has so much torque and power now that i,m not driving it hard enough to generate enough heat? 

 

both coolex and davis craig recommended the rad size and pump to suit the car and its engine spec.

 

Not sure what to do now any ideas and opinions please

 


Davis Craig Ewp115 Electric Water Pump On My Zetec

06 September 2017 - 06:37 PM

One small issue I now have is I cannot get my zetec hot enough it runs at 80deg and takes up to 15 miles to reach temp. The new cooling system I fitted is basically to good, getting a suitable stat for the race line waterrail is limited and getting more scarce by the day it uses the old X flow stats.
The electric pump will address all issues, fast warm up and ability to select running temps then the engine cool down after a run. 1 other bonus is increased power and a better mpg (apparently) Will update once it's here and fitted.

Ironic really all the trouble people have trying to keep there temps down and i.m trying to raise mine.

Supercharger Boost Control

06 September 2017 - 05:31 PM

Started a new project today to try and tame the boost when trying to cruise @70mph. The idea is using a Mac 3port solenoid boost controller and a mini vacuum pump. The plan is when I switch to economy map it will switch the valve over so the plenum vac line to bypass valve is closed stopping boost pressure at the same time the mini vacuum pump then pulls the bypass valve open thus stopping boost. Hopefully then I will be able to drive at 70mph without boosting to warp speed all the time... Will update when I have made and fitted it all.

Just bought one off burton power For £43.87 ! when it turned up it was in a Cambiare box with a part number of VE363408 with a http://www.burtonpower.comsticker over it.  if you search this you will find it for about £26 every where else, typical burton power really nice mark up...
