2.0 Ltr Engine

[andyiow]

Hi I have just taken delivery of a 1998 2.0Ltr Bongo. Is the engine used in any other Mazda please? I also have a noise when starting up which sounds like a lollypop stick in a bycicle wheel! This goes away when the engine reaches working temperature. The coolant levels are fine and there is no water loss or any sign of leakage. The temp guage doesnt move above the 11-o-clock position so no overheating. The only thing I can think of is perhaps the waterpump but would that noise stop when at working temperature

If it's the same as the diesels it never does, UNTIL the engine is cooked.

The standard gauge is so insensitive that it is useless - do not rely on it at all.

i believe the engines are in the mazda 626???...i to have just got the same and there is no noise on start up like you describe?.....

Thanks for the info will have to look into the noise. It only happens in the morning after being parked up overnight its fine during the day. will look at the 626 for any more info

Calm down there Scanner. No need to scaremonger a newbie!!


There is an element of truth in that though.

If it sits at eleven all the time, its likely to be an unmodified temp guage that won't start climbing until about 115c which is around the critical limit so unless you can react instantly the chances are its too late.

Do a search on here for a Mason Alarm. It undamps the guage so it reads more accurately & has a settable audible alarm too.

A doddle to fit & greater insurance on longevity.

Call THAT scary?

No where near as scary as relying on a kak temp gauge until it tells you the engine cooked itself 5 mins ago.

Time after time folk have posted on here that "it can't have overheated as the gauge didn't go over 11 o'clock!" then asking where they can get a head cheap.

What worries me is this apparent run of 2 litres that have had the thermostat "modified" so that they now run too cool to warm the heater up.

One can only ask .......WHY?

Thanks for this I will look for a coolant alarm on the Fury site. I have to say that opening the engine bay it does not look to be running hot and I have just taken her for a long run. Still I take your advice and will get an alarm.

To modify the standard gauge to read more accurately, you need a "Mason" alarm which you buy direct from Dave Mason (a search should turn up the link) not from the Club site.

A low coolant alarm is a different beast and may or may not include a temperature read out dependent on the model you buy.

I think the ticking noise on start up could be a "sticking" valve lifter.....halfords have a product which fixed our car..
See the website below for a coolant alarm

Hi thanks whats the product halfords have please

Valve lifter unsticker Sorry, couldn't resist it try this http://www.halfords.com/webapp/wcs/stor ... yId_165750

A lollipop stick in a bike wheel sound could also be something more benign than a sticky lifter or failing water pump: have you tried to pinpoint exactly where the noise is coming from? You can pick up an automotive stethoscope at Halfords or similar -- or take your Bongo to your friendly local GP surgery...

Some Bongos seem to suffer from heater blower motor problems/failure, and the blower motor could be making the noise. You don't need a stethoscope to test this one: just turn the fan off when you hear the noise. If it stops, then the blower motor needs attention. The blower motor is vulnerable to getting water in it if the drain hole under the centre of the windscreen gets blocked.

Hi,
it might be worth checking your power steering fluid (under drivers seat)it could be the PS pump rattling, although this usually goes away when you put a lock on the steering its worth a try.

Thanks the noise has stopped now after flushing the engine and an oil and filter change plus addatives. Wondering if it was the oil pump!!!! Still oil pressure ok so probably not that. I did have to unblock the drain hole also the other day
