Lots of coolant all over the tarmac!!

Bongo has lost its coolant. I noticed it all over the tarmac today. It has been running quite normally and still appears fine in every other way. RAC have been out and they think it is the radiator losing fluid from the top left hand corner (when looking at the front of the vehicle). It doesn't appear to be anything to do with the head gasket. The temperature gauge appears normal too. (note: it has not been driven since I noticed the problem except to reverse it into its parking space when lowered from the recovery vehcle.)
Question : How can I be sure it is not the Head Gasket?

I've heard of lots of radiators that have leaked just where you've described, without involving problems with the head gasket.

sounds like a radiator gone to me.........I had a similar on mine but towards the bottom front of the radiator......I too stopped and didn't run until I replaced the radiator.......I also have a low coolant alarm and I had not lost enough coolant for the alarm to sound, I guess if you have an alarm fitted and it didn't sound then your in the same position as I was.......just a radiator split ........ changed and coolant flush too......all better, well has been for the last 3,000 miles since July

If it has not overheated, it's unlikely to be the head gasket. The radiators have been know to split on quite a few occasions.

If you're relying on a standard bongo temp gauge to tell you anything, you're wasting your time, by the time it moves, it's too late, as discussed on here endlessly, it's dumbed down to be virtually useless.
Saying that, it does sound like it's just a split rad. If you haven't already I'd recommend fitting a low coolant alarm & a Mason Alarm to resensitise the temperature gauge (or the modification outlined by Haydn Callow).

Please remember monkey, despite what you read on here, head gasket failures are no more common on a bongo than any other car with an internal combustion engine... A VERY small proportion do have head gasket issues from time to time, the majority never suffer from any "head issues!" I can recall offhand just ONE forum member that I've met down the years where "his head had gone" (that's cylinder head, I've met more than one forum member with real head issues :lol: ) So, I'd worry not my friend... I'd suggest though that you may want to change your forum name...The other forum member who's head had gone was named after a primate! :shock:

Doesn't stop you getting paranoid though!

Since I had a pinhole leak from a hose the other week I've been a bit preoccupied with checking coolant levels, watching for leaks etc. You don't realise until you start looking just how much coolant there tends to be lying in garage forecourts, car parks etc. It really doesn't help! :shock:

Thanks for advice. Just refilled with coolant , ran the engine for a few minutes and everything seemed normal, running smoothly, no unusual noises or smells. So fingers crossed it is just the radiator. After the engine was switched off the dripping started again from the same location. I will try to "keep my Head" and as for primates, I'll carry on taking the risk!After all, I've got broad shoulders (and rather long arms!)

Have you tried wedging a small banana in the hole in the rad? :lol: Chances are it's not actually a hole, more likely to be the actual rad section starting to seperate from the outer plastic housing... The only important thing to remember here is to maybe limit your journies to just one trip to the garage/mechanic/yourself...and above all, ensure the cooling system is properly bled! Many methods are available on here, all seem to do the trick (if carried out properly) Best of luck... :wink:

Yes, i quite understand Catzi..But the amount of "heads" reported on the forum is disproportionate to the amount of peeps that post "my cylinder head has survived yet another day" I've had my bongo for over five and a half years, that would be 2000 posts where i'd just said i've not had a cylinder head problem today! :lol: I do understand the paranoia though..I too bought all the hoses, alarms etc...And yes, i do look at the temp gauge more than the fuel gauge, mad isn't it? :D

Well I am looking at the 2nd cylinder head replacement required in 3 years, so I have moved from 'paranoid' to 'persecuted'. I would disagree with the comment about not being more prone to this type of problem than any other vehicle with an internal combustion engine. I have owned many (vehicles) over the years and (with the possible exception of an Imp many moons ago, have only lost my head twice, both times with this beast. :(

Hi Mondo...I'm sorry to hear that mate, but that is unusual! Was the first head one of those crappy chinese e-bay jobs? They really are of a horrendous casting... I liken them to an expensive paperweight!

Ha! Ha! You're quite right. Now, I must remember to check the coolant level tomorrow morning :lol:

Hi Big Daddy..

As for the previous head I think, as I recall, I bought it through this website.... But I do remember thinking it looked a lightweight flimsy thing to be sitting on top of thousands of explosions. Albeit small controlled ones.

It was fitted by our local mechanic who is a thorough and well trained guy, and who has repaired and serviced our Bongo since we got it about 7 years ago, always to my satisfaction. This first incident was after some period when we'd had a number of coolant loss problems (water pump, hoses) ultimately it went just as we were to board a ferry to France (so the long laden up trip from Manchester to Portsmouth didn't help. We'd also had an overheating episode on that journey. Anyway I can kind of understand the pressures and strains that would have resulted in a cracked head on this first occasion, which I believe was around May 2007.

With the new head fitted we seem to have enjoyed mostly trouble free motoring in the beast (aside from one curious overheating incident not long after the new head. We stopped on the side of the m6, noticing a dramatic rise on the gau ge) waited a good half hour or so and checked the levels to find find hardely any coolant loss. Topped it up the little that was required then I cant say I can recall an overheating problem since. I believe this incident may have been due to an airlock).

Then, this recent occasion occurred thus.. (I'll admit I hadn't checked the level in the expansion bottle for about a week before the incident. And I had been driving it locally ( say 10-20 miles per day). Ordinarily I would check the oil and water prior to such a trip as on the day it went. (ie a 70 mile round trip on the motorway) but on this occasion to my shame I hadn't. My partner was following me from Manchester to Chester, I in the car (with 2 sons) she in the Bongo (with other son, wife and the 3 grandkids). I got the call that the vehicle was broken down near the M56/M6 junction, and words like 'smoke' 'steam' and 'loss of power' were mentioned.

By the time I had dropped my payload and returned (we were all heading to my mother in law's 70th birthday barbeque) so she could take the car and I return to Manchester with the sick van on a recovery low loader, it became apparent that the bottom radiator hose had split. Back at my place, when we tried to fire up the engine to reverse the vehicle onto my drive it became clear there was a complete lack of compression.

My problem now is, obviously, her, and to a lesser extent, my confidence in and liking for the vehicle have been somewhat impaired by this second expensive repair incident. Another related problem is that, due to a couple of prangs I have had with it (involving reversing into a skip (duh !) and scraping it on a gatepost, .... that although after it has this second head fitted it will be relatively low mileage (c. 100,000 miles) its resale value has been seriouly dented by the, well, in some peoples eyes quite serious dents.

I like the Bongo !! I like the way it looks, and drives, its comfy, esp.. on long trips (we are both 6ft) and I love its multiple functionalities. Also I like the fact that this forum exists to help out owners. Maybe I should have made more use of the site during my several years of membership. One thing we have never liked though is the fuel consumption. But I can excuse this since the vehicle is effectely a van. And a B & B when the need arises. But what I am now vexed about is this coolant achilles heel.. I have tried to look after and maintain the vehicle as best I can (regular servicing and checking levels,. I even undersealed it last year, the body work is in great nick (apart from my dents...) but if I am going to be looking at having to fork out around a grand or more each year on sorting out the cylinder head then it may need to go. What concerns me is that the first incident could perhaps be attributed to carelessness, but this second one has come out of the blue. And I am now starting to think it could well happen again in a year. If the answer, to give me peace of mind, is to need to check the thermostat, replace all the hoses, flush the entire system, fit an audible alarm in the expamsion bottle and never play my music too loud in the cab, well, I guess I could do all these things but it seems rather excessive to be able to enjoy cylinder-head-breakage free motoring. But in my case, with a dented and scratched nearside rear end, it could be my only option.

As a result I don't love our Bongo as much as I used to . :(

And my missus has developed a dislike for it. Initially the high driving position was one of the reasons we got it (to assist with partner's sciatica) .. It is now causing disagreements in our happy home.

Any suggestions ? (other than the obvious 'stop moaning and try'n drive more carefully (especially in reverse.)). ( or get a different partner) etc etc
??
Sorry for the rant ppl but these 2 x cylinder head jobs will have ended up costing more than I paid for our other car, which is an excellently running Mazda323. Grrrr.

PS we never look at our fuel gauge. Its always been broken. We just make sure to fill up every 250 -300 miles. then press the odo button.
