Pinto 2.0 water temperature

[kliobas]

I guess I put it right way as I had some considerations about it. Is this correct?



Now not running turbo because of other reasons

Now not running turbo because of other reasons

thats correct way round

[alladdin]

Is reading temp from inlet reliable ? It's not really engine temp is it. Why not read water temp

he will still be reading coolant temp, efi pinto has temp sensor in the manifold heater take off

My cosy in my mk2 with cosy rad has always sat at 90 deg what ever I do with it
So 85 prob ok

I think I will remove the housing and check, now I'm not sure that it's in correct position. Thanks Graham

[Graham]

if the thermostat is the wrong way round it will open but not until the engines nearly at boiling point

[kliobas]

Mine has a hole as per recommendation in this topic, so by using bypass it could open earlier if it's wrong way in housing

Having a thought people, I'm running a reasonably powerful turbo pinto (little over 300bhp) and am curious about running water round the back of the block through that bung on the side, i can't quite figure out how to plumb it up though whilst leaving the heater matrix connected and water running to the turbo.

If im correct, the water comes OUT of the inlet manifold, then into the heater matrix, then into the turbo, then into the water pump. Could i run the coolent out of the turbo into the bung into the side of the block and blank the small water pump connection. Or will doing it this way put more heat into the back of the block as its hot water from the turbo.

So the thermostat was put in a correct way ...

Any other ideas why the temperature is higher than using stock hotter thermostat ?

No one got any idea on this one? I understand i don't think its been done before so trial and error but any advice/thoughts would be appreciated.

I have been thinking about something along those lines but never really finished the thoughts.

General advise here in Sweden with regards to turbo cooling is to plump it so it can self circulate when the engine is off (to aid cool-down). I never did that when I had a water cooled turbo though.

I would be interested in more brains on this :-)

Hi,
If i do not have a heat matrix fitted and blocked the outlet on the manifold and small inlet on the pump. Should there in this case be enough circulation in the cylinderhead when the stat is closed?

there are plenty of pintos plumbed that way

[Frits]

Ok, and what if i plumb the small outlet on the right side of the Block to the small inlet on the waterpump, would there be still enough circulation in the head? We now Run Without a stat, but enginetemps het high in heavy stages (110deg C ocasionally)

[Graham]

no thermostat at all is a bad idea, the coolant will not circulate around the back of the engine, just remove the middle section from the thermostat, that way there will still be some back pressure in teh cooling system which will force it around teh whole engine rather than just around no 1 cylinder

[alladdin]

great thread this

[DarthVader]

I actually ran a feed pipe from the waterpump (feed that would go to the heater) to the rear side of the block on a race pinto. Got the idea from Roger Miller here on the forum. There should be a thread about it if u do a search. T

Think it help here in our hot climate

Thought I’d post this here as I thing it’s related

Does any one have any information regarding the normal operating range of air intake temperature on a naturally aspirated pinto? And where it is measured?
What temperature is best for power? And at what temperature power starts to fall off?
