New turbo IP now engine running 10-15 deg hotter???

[derekp]

the car is a 92 eco diesel. Pump died. I had a turbo pump core so I exchanged for a rebuilt turbo pump from reputable source.
Pump on car - car still has stock eco diesel turbo on it.
Timed to 1mm - rechecked my effort 3x and all 3x its 1mm.
Car runs pretty good - minimal smoke - more power than before (250kmiles on the pump that quit)
Problem - I think -
it has the stock 87deg C thermostat in it. (new one too)
Its 30 deg here today - I ran the car and it seems to be running 10-15 deg hotter than it used to.
The stock temp gauge (in these temps) used to struggle to get to the center of the gauge (i.e.: "straight up"
after the new pump install its straight up (half gauge) to almost 3/4 full range of gauge. moves between the two points.
Also have a separate temp gauge in car and its showing 183-195 degrees cruising or climbing hills.
In this weather - that external temp gauge rarely got above 175 with a radiator cover in - today I had to remove the rad cover!

Also, I DO have the line connecting the intake port to the aneroid properly so assuming  the aneroid is working properly, its getting the boost signal

I'm somewhat concerned about this higher coolant temp, esp in these outside temperatures.
I do not have exhaust temp gauge available to read ex temps and putting one in now is a bit much to take on at the moment.
Anyone got any ideas why Im suddenly experiencing higher coolant temps?

Stock eco had no boost enrichment... now you do.

Mo powa, mo hotta.

With a new 87 C thermostat you should be fine.  Since you have a secondary gauge just watch it as it gets warmer this spring.  If it really gets and stays hotter than you would like you can always swap down to a lower temp one later.  But the diesel might like the warmer temps.  You might try backing off the fuel screw some if you have more fuel going to it than your liking.

With a rebuilt pump 1.00mm could be too much advance. It's almost certainly more than the old pump which could cause the extra increase in temperature.

I agree with post #2

ECOs are set to 1.00mm, they have 155bar injectors.

Yeah, I thought about the fuel screw too - but I figured (hoped?) that a newly rebuilt pump would have a sane setting ?
Unless some other ideas come in thru here, I'll drive it, watch the temps (esp when it gets warmer out) and watch the fuel mileage.
If the mileage is down and the temps stay up, I guess I'll try backing the screw out 1/8 to 1/4 turn at a time and see how that plays out.
Power certainly feels up compared to before. Seems to peak out faster in each gear too
I gota get someone else to drive it so I can see how much smoke I'm getting, but it seems a lot less smoke now (as viewed from the rear view mirror aspect anyway)

I may also try simply disconnecting the boost line to the compensator (ECO diesel pump did not have compensator) before I go cracking on thefuel screw

i think the pump timing for you 0.96mm pump and possibly leaning out the pump some,
(also; new fuel/air filters?;use a good amount of additive for fuel). you have more at pump so more lube in fuel cannt be a bad thing.

Is the Eco exhaust with cat still in place?  Cat plugging from extra soot = increased back pressure and temps.

[derekp]

Car has a full tectonics exhaust on it turbo to the tail
K&N air filter - freshly cleaned
Given the lack of smoke (well - minimal as viewed from my rear view mirror) I'll leave timing alone for a bit
(old pump - lots of smoke before it crapped)

I'm gona watch it for 2-3 tankfuls of diesel before I go changing things around
Probably
1. disconnect boost line to compensator first
2. put that back on, back out fuel screw (esp if I see my fuel mileage is down compared to old pump)
3. back timing off tiny bit

this mornings run to work (40 deg outside) and it hovered in the 180-185 range.
Really need to see how it does on a warm day - whenever THAT may next occur
thanks, all,  for the pointers.
