Water Temp Increases Faster After I Change coolant

[Mini-itx]

I am previously using water wetter and tap water. Decide to change it to Motul additive and distilled water because some of my hoses seems to leak with WW.

 

I realise than my water temp now rises to the middle point faster than using WW. Is this normal? Cause it could mean 2 things, better heat transfer or engine producing more heat (due to friction, oil pump problem?).

you just change radiator block right? sure the radiator not giving you problems?

Nope its working fine. It just that temp moves slightly faster to middle point than before. After that it just stays there. Thus no overheating issues of any kind.

If there is no signof overheating, the difference is fine

If the new coolant affects the oil pump, can be time to overhaul engine (they are isolated from each other)

When you change coolant, did you flush out completely?

 

Coolant does not like to be mixed. It can form sludge.

OK, I have checked with Motul and its nothing much. They said its supposed to allow engine to heat up faster due to better thermal transfer from the cylinders to the water.

 

OK, sounds plausible since these additives are supposed to improve thermal transfer compared to plain water, hence improving cooling.

Yes of course, I bought 2 cartons of distilled water to flush.......

as long as the temperature is not higher than ur previous level.. i think the speed it rise is not really a problem...

You should check water level before moving in the mornings. I had the same problem before. For some reason u need to top up water after a radiator change as well as flush after a few days IMHO

Did that happen after you flush your coolant? If so, its due to the air pockets in the cooling system. No choice one, need to check for a few days then water level should not drop anymore.

Check the quality of coolant, some coolants are only water with solvable color.
