Cavalier 2litre

[Kurtupsin75]

Hi all best battery for a cavalier 2litre got a 44amp hour fitted new bosch type  but hard to turn over any ideas in size of battery. Thanks

I put a 60ah Battery on the Manta last year and it has been fantastic on a car that doesn't get used every week. I do keep it on a trickle charger now, as standing for long periods without any use will kill a battery quite quickly.

After shopping around, I went back to Battery Megastore. who I have used a few times before and they came up trumps again. The Bosch S4004 battery was £65 including Vat and delivery (and it came within 2 days). Price has gone up slightly now but it was much cheaper than local motor factor and half the price of Halfrauds.

the largest battery you can fit without any mods is a 100 size .this just fits in the gap perfectly.

dont let a supplier give you a 096 tho saying they are the same ! they are taller and will hit the bonnnet.

a 100 is the same height and depth as a standard 063 size original battery just longer.

BUT

theres no reason at all that a standard battery should have any issues turning over a 2 litre engine .unless the engine has been modified with too high compression or theres an issue with the starter itself or cables. 

usual issue with these cars is the engine earth lead. if thats loose,broken or missing it will turn over slowly.and also burn out the speedo and clutch cables too !

 

once sorted you should be able to leave car untouched for 2 months easily without any issues.

Maybe earth is insulated with all that beautiful paintwork. 

Maybe remove starter and jump it, see what its doing removed.

Is there anyway of testing if it is earthing through speeding, clutch cable. 

[cam.in.head]

if the engine earth cable is good(or new) and tightly attached to bare steel all should be well.if it gets faster if you put a jump lead across from engine block to battery neg then the earth cable is not doing its job and you may feel clutch cable getting hot .or the connections at either end of the engine earth cable.

at lot of people forget the engine earth when putting an engine in.probably not the case here but worth asking.

if we are sure that side of things is ok then its either 

starter problem

engine too tight

ignition timing too advanced

I had with both my engines the same problem, fitted on the GSI with 2.4 engine the starter of a Omega 2.4/3.0 24v (they are the same on both engines) problem solved. Later after some updates of my "400" engine I cleaned the copper collector and the starter did his work better. But after the latest overhaul of the engine (higher compression etc.) the starter failed again so fitted also a starter of an Omega. Noticed also as Cam in head wrote above the timing (too advanced) had big influence.

[cam.in.head]

we will see what keith finds out.

 it shouldnt be a battery issue as a 063 was always sufficiant even on carlton 2.2 engines so a 063,075 or 100 will work.

timing easy enough to eliminate if it turns over quick with coil unplugged( hence no ignition to fight against)

so its either.

engine earth ( my guess)or other connections

bad starter ( replace with same ,all cih engines ,best type 2.4 or 6 cyl versions fit too)

Thank all the advice all cable earth  all probably cleaned metal to metal surfaces stuck on a bosch 60amphr battery has helped on turn over but some time it don't engage at all just clonk sound from the stater does twice third attempt it starts cavalier automatic as well .

[cam.in.head]

ah well in that case it sounds like either bad ring gear teeth or starter itself.(possibly just solenoid ?)providing it spins it well once it finally engages.

ring gear is part of flywheel( flexplate on an auto ) although it may very well be replaceable but either way is a gearbox(or engine) out job.

if you remove starter you should be able to examine ring gear for damage. not very common on these engines thou.hopefully it will be a starter issue .easy to find and plenty of choices.

if it does turn out to be ring gear you may be able to get a file in to repair any localised areas .fiddly but easier than g  box out !

 

if you are 100% sure all cables are fine then see what you see once starter is out .

[Kurtupsin75]

All the teeth are fine flywheel been fully inspected before assembly starter new recon unit something not right possible timing is the issue 

[cam.in.head]

timing being out ( too advanced) could be proved by unplugging the coil and then cranking but this wouldnt cause the actual starter motor to not engage with the flywheel as you described .more of a struggle to get past top dead centre as it would be firing too early 

 if teeth  are fine and unplugging coil makes no difference then its a suspect starter to me . but see what you find.
