Pinto swap ??

Hello,

i have a temperature problem that i can't solve with my tiger Cat.
Engine is a 2.0 SOHC EFI pinto engine with a type 9 gearbox runign with standard ford ECU.

the engine runs well , but it's runing very hot.
the temperature indicator is always around 100-105 C.

It gets so hot that the tunel panels are very hot to touch.
So , i checked the way my cooling circuit was made, it seems to be fine when i compre to other's setting.
i changed the water pump, the thermostat but no change.

So , i am thinking in taking the head out to check what's inside.

my problem is what to do if there is a big problem inside.
i can't find another engine for a direct swap and i don't want to go carbs.

So what would be the best engine for a direct swap ?
i don't care about the side the exhaust are , but i would like to keep the gearbox.
i also have a KMS ECU kit that will fit a Duratec engine or could be adapted to another engine, but i would prefer to keep it for another build.

thanks for your advices,

Gerardo

What thermostat do you have fitted? What fan and how is it controlled? what ventilation does your engine bay have?

I've done a pinto to Zetec swap - the pinto was on bike carbs and did about 2mpg and the Zetec was fuel injected and was beautiful on the standard ecu.
I did cheat because the Zetec came out of a kit already and the wiring loom hard work was already done. I actually made money out of the swap because I parted out all pinto bits - block, carbs, air filter etc.

if you do decide to go Zetec, I've got a stock ECU here with the pats key immobiliser if it's any good to you ??

Thermostat is 85 C, new polo radiator, fan behind the radiator and sucking air, fan kicking and stoping as it should, vent holes in the bonnet on the exhaust side

First, swap thermostat for an 82 degree one or modify mini 78 degree one, this makes a big difference
If you don't have a header tank fit one.
If this doesn't work fit a twin core radiator with more cores, I run 42 core radiator

Also check ignition timing as this can affect engine temp and fuel mixture as running lean also causes hot running

^^^ what he said, make sure the engine is running right first, it would only take a dead sensor to mess up the fueling (and its not like you can plug in a scan tool and look for error codes on thee prehistoric ECU's...)


But you should also check how accurate your temperature gauge really is - it could be telling you 105C when its actually only 90C the calibration is almost never exact...


Then I'd look for possible air locks in the coolant circuit

The 2.0 Pinto in my MK Indy ran about 90-95 degrees C with a Polo rad, standard Ford water pump and thermostat. I can't recall the thermostat rating, but it was a standard Ford part. 100-105 degrees C sounds too high for my liking, but if the system is plumbed OK it's hard to see what problem you have. Do you have an oil temperature gauge? If so what does that read as water temp can be affected by oil temperature I believe.

Have you checked the temperature gauge is accurate? Rig up the gauge on the bench with the correct voltage applied. Put the sender in a pan of water with a good thermometer and see how the two compare.

Check the ignition timing if the spark too retarded will result in excessive heat being rejected to the cooling and exhaust.

Also check the by-pass flow is connected -- ie water is continuously circulating in what was the donors heater pipe work.

To check the gauge buy a cheap K-type Thermocouple thermometer off ebay see

DUAL TWO CHANNEL 2 K-TYPE DIGITAL THERMOMETER THERMOCOUPLE SENSOR 1300°C

Ok,

i will check timing, exhaust gas and bypass flow to start.

thanks for your advices.

back to the initial question : what woyuld be an easy swap for the engine ?

In my opinion there is no easy option however if it were me I would look at an engine where he intake and exhaust are the same size as a Pinto
That said only the Crissflow, CVH & Zetec actually mount straight to a type 9 gearbox
