New Water pump

[Triple/R]

Check the rubber water pipe from the top of the block under the drivers seat, often cracked on the bend.

Cheers mate~all the hoses i can see are all ok~but thanks anyway.

As you have the shield off the bottom of the engine it may be worth doing what I tried. A half sheet of hardboard under the engine bay overnight and when getting home with the temp up. The board will stain so evaporation on the floor is not a problem and will possibly point the way to the loss.

Ray..... your worrying too much Matey...... Steve & I told you at the bash.....

I know what we discussed but i'm putting about half a cupful in about every 2 weeks,also i fitted my coolant alarm (so i could be alerted) & thought i would see if the coolant would find it's own level so did'nt bother topping it up,after about 3 week or so my alarm went off & the coolant was on the lower level so the coolant's going somewhere do'nt you think?

I know i'm a worrier Mike but it's doing me head in

seems like there is a loss somewhere....but minimal as it took 3 weeks to drop.....if it isn't external then it could be internal somewhere........my Low alarm "hung" on for about a minute yesterday.....and guess what.....my coolant it full.... Must be a tarnished screw giving a false alarm.....oh well little job tomorrow to replace it with one of a higher grade of stainless....

Hi,

I have exactly the same problem with coolant loss. I thought it was a cracked head but with the help of the clever people on this forum I have fianlly proved otherwise. In my case it certainly seems to be the water pump.

The way I found the problem was to buy some flourencent UV dye and a UV lamp. This took some time because both components are not cheap and I managed to find/borrow them.

By putting 70ml of UV dye into the header tank and running it for half an hour allows the dye to get into every last nook and cranny of the system.

I then put it on ramps and got out the UV Cannon (from my uncles night club) which lit up every last spot of white under the car. Importatly though, it highlighted a thick and very flourencent stream of coolant running down the front of the engine from behind the water pump pulley wheel.

After a huge amount of faffing about, the dye is the only way to find these leaks. If you still need help, I can get you the number of the dye people.

Goood luck, Joel.

Cheers Joel~everything is worth trying to get to the bottom of the problem.

if you have Red coolant in your system it will show leaks like this....

Not a Bongo engine but you get the idea

Cheers Mike~good info as usual.

Hi Ray
I agree with Ady, but have you got wet carpets by the heater?, and have you checked by the rear heater for darkish patches around where the hoses fit the stubs for the heater...if there is water loss, it accumulates by the hose where it clips on, and the road dust congeals in it...Have you had a new rad?...sometimes a minimal leak can go on for ages.....
Cheers

Thanks Helen ~theres no wet carpets around the heater but have'nt checked the rear one.

Hi Ray
One of the problems I had (as have a couple of other members), is that when I replaced the hoses, some of the stubs to the heater matrixes disintegrate when removing the old hose...not your problem, BUT, they seem almost crystalline in appearance at the ends of the broken bit...very much like looking at broken bakelite, if you remember that!.. ...and my point is, that the plastic seems to become a bit brittle and age-hardened, and there may just be a PIA waiting to happen...I replaced my hoses...all was fine, drove onto the drive before opening the yard gates, and the LCA went off...turned off the motor in the yard, and the stubs had failed (after a 110 Km round trip)...coolant a-gush...Helen Aghast Luck, or what!
So...look very carefully at the matrixes....
Cheers
Helen
