Thread: tranmission overheat

Have just had a Territory transplant done on my D3, and in process had the EGR valves blanked and fitted with emulators.
Biggest obvious difference is that engine appears to run very much cooler, as coolant no longer being heated by EGR valves. I find that from cold start it can take 6+ k's to get up to middle of temp gauge (usual place my car has always operated at), and if running about town, it will drop from half way to quarter from bottom of gauge, only returning to centre when I am sitting on open road running.
When the pace slows down the temp gauge drops below half.
I figure that will have to help the transmission stay cooler.
Perhaps blanking EGR valves is a "quick cool" option.

Blanking EGR is not a viable option on later engines... closing them is but requires remapping.

(Yes there are emulators but these are proving flakey)

Mine does take longer to warm up,particularly in cold weather,since egr's have been blanked off.

After warm up,i don't think there is any difference in operating temps.

Maybe one or both of yours were stuck open,even slightly,may have caused the engine to run hotter,before they were blanked off.

What is also noticeable is a lot less smoke out the exhaust when it gets a boot full, than before.

that much fluctuation could mean your thermostat could be partially stuck open , do you have a gap tool , nanocom etc to measure?
x2 re the emulators being flakey
