Engine Turns Over Slowly When Cold

[jims-terrano]

My engine turns over slowly when it's cold, took three times this morning leaving it time for the plugs to heat up. Once it's been running it's fine no problems at all. I replaced the battery in about Feb March time this year. Once it's started I cant see much in the way of clouds of smoke or anything like that. I'm going to make a cable from my multimeter and cig lighter today to keep an eye on voltages this week, any idea what voltages I should be looking for and when.

Charged Battery in good condition should read 12v or just over

Charging (with the engine running) should be in the region of 13.8-14.2v

Depending how clever the alternator is (not sure on these T2s) it may drop back to 13v (ish) once the battery is charged.


Have you checked all the connections at battery and starter and earths - if its not the battery these are next most likely and also of course the starter itself could be getting "tired".

when you fitted the new battery did they supply the right amperage? and are you using the correct grade of oil? it may be the wrong vicsoity. and is to thick when cold!

I always press the clutch down when starting, saves having to turn over the gears in the box as well.
I use Molyslip 2000E for engines, I notice the difference, it turns over much faster and easier than it used to.
Could of course be bad connections on the battery.
You probably need a CCA ( Cold Cranking Amps) of approx 850 Amps.

If youre lucky enough to get access to a fully charged correct spec battery and it still cranks over slowly, check the starter motor runs freely.

I've no experience of this on a Terrano but I had similar on a Sierra a while back.

Basically the starter was very tired (non technical for almost worn out knackered for various reasons) Classic problem with those though was when they finally gave up the ghost they often shorted straight to earth and discharged your battery, on mine it went in one go, a ford mechanic at the time said that was quite common but they also leaked to earth in a more gentle slow manner too whilst playing up.

Good luck.

Had the same problem with my T2.

It was the starter motor, it was pulling excess amps, them it died taking the nearly new battery with it :twisted:

Check how many amps the starter motor is pulling when its turning the engine cold.

Or it could just be the new battery :lol: it's a mine field these sort of problems jim.... it's like where to start :roll:
Good luck m8.

had a similar problem once .... battery was ok with no load ... as soon as there was load it lost power .... anyroadup, good luck ...

Well guys thanks for the replys, I think to begin with I'm going to test the volts and see if anything nasty is happening. I certainly don't fancy playing with the starter motor.
