My cutting out issues

[weejoe]

So my van is back at syncronutz

It's cutting out after about 1/3 mile

Could this be due to the overheating ?

I had a leaky water pipe replaced somewhere just below the fuel pump.

Does the system need bled ? Could the system be airlocked ?

Could a faulty fan be the cause ?

The temp gauge was up at about 3/4 although I think this was a false reading due to lack of circulation as the cllant shot out geyser style when the RAC man tried to crack it open.

Ian at Syncronutz stuck some of that powder stuff into the water system to try and fill the leaky pipe before I went ahead and got the pipe replaced.

Could this have gathered somewhere and caused a blockage ?

There is a slight wobble on the water pump puller wheel when it's running, does that mean the pump is knackered or is this common ?


Sorry for all the questions, I'm just trying to get it into my head what the fault could be.

Cheers everybody

I'm sure Syncro-Nutz will establish the cause and sort it! All sorts of secondary factors could creep in, once you start having cooling problems.

The wobble that matters on a water pump is not a distorted pulley but whether it wobbles when not running (e.g. knackered seals or bearings)

weejoe,
Just a couple of thoughts on your problems.

You probably have two separate faults here.

The cutting out sounds as if it could be a fuel supply issue connected with the tank replacement. (Trapped hose, blocked vent, debris in tank.......)

The coolant, air trapped in system after pipe change, almost certainly a bleeding (or three) should fix.

Syncronutz seem to be well thought of in the club, and although the timing of the breakdown could not have been worse, chances are things will be sorted fairly quickly.

Hi weejoe The so called over heating problem(if it is,i am sorry but i never take someone elses diagnosis to hart until i have inspected the vehicle myself)is definetly not from an air lock.I did the water pipe myself and bled it myself( and i have done this hundreds of times over the past 2 decades)
The van is outside our workshop at present but havent had a chanse to
look at it yet.Unfortunatly this vehicle needs an lot of attention to bring it up to a decent standard(mechanicaly)The cooling system is bodged together with all sorts of pipes underneeth.I did a preshure test after finishing the replacement of the small pipe beneeth the
crank pully and this was satisfactory.(one can only economicaly do so much)
Unfortunatly when someone has just bought an old vehicle quite often it means
taking on some problems.(especialy an old camper)

Unfortunately when someone has just bought an old vehicle quite often it means taking on some problems (especialy an old camper)

So, so true, I think this has to be borne in mind by many, and in fact should be a std warning in the Wiki and on the Vehicles For Sale forum - these are now old vehicles, with usually many miles, many owners, and were anyway the last of a line and were quite complex beasts in some ways and as such need the right parts, mechanics and approach.. that said, in good nick, we all love 'em. But being honest, you won't find many mechanics jumping up and down (in glee, anyway) when they see a dubious one

Well the cutting out is(was) the hall sender in the distributer not feul related
like diagnosed by the RAC man .The vehicle is not overheating(it did need to be rebled bue to the RAC man opening it when hot) the guage
just reads at 3/4's.This is a compatability thing beetween the sender and the guage.After all these things are not accurate.
Please people dont take to hart whot people say(diagnose)on ure vehicles unless they now T25's.
Had a Dutch couple last week with oil light on AA man had a look said it was a faulty buzzer.He then said it was fine to drive.In the mean time
it was a loose vacume pump wich affects oil preshure and brakes.In turn this causd a lack of oil in turbo,so good by turbo.
A simple tightning of size 13 bolt could have saved them £480.00
They are luckey they didnt blow the whole(recently fitted) engine.
