I have used this product for Rolls as well as Porsche and moderns with water pumps driven of the cam belt etc with no cooling system probs over the years! but no longer. After many years of useing the lube for the water pump etc it seems it gives a protective coating for the alloy and hoses in Rolls Porsche and other more modern cars that have been known to shred their cam belts[real cause water pump failure through seal and bearing failure] i found our stocks exhausted. This was working on my Porsche as the coolant was due to be replaced to long life antifreeze [note distilled water as well] and a belt tensioner. After a call to the agent we got talking about the different Porsche mods and recomendations of which the w/pump subject came up, he said all the cars have the modified type fitted by now. I pointed out that the third pump fitted[ original type] was still on the car and in good form, fitted in 1995 and no leaks. He just could not believe it so i and told him what we do or did! This was i believe because of the use of Holts water pump lube that has now been discontinued confirmed by head office. Dam. Well i suppose we may well find our customers with the moderns with a cam belt failure real cause w/pump sezure in the future. Any ideas on anyone on the use of the screw cutting agent[soluble oil] maybe effect on the seals and antifreeze [long life]??? We must look after the alloy blocks as well as pump corrosion. The company [holts] have given me the formula of ingredients but not having much luck yet with what they are. Probably i spelt them wrong. |

I used soluble oil many years ago in a Transit V4 on the suggestion of a mate because he reckoned it did not freeze. It does freeze because we put some in the fridge. Also it rots rubber hoses. I was told by an old mechanic that putting an egg cup full of engine oil in the water would help lub the pump seals on cars fitted with glands rather than carbon face seals which are used on modern pumps. I dislike cam belts and dislike even more cam belts that drive water pumps. Because if the water pumps fails it could cause the belt to fall off and of course there are no push rods to bend only valves and pistons to damage I was pleased to find that my Jeep has got a push rod engine and a chain. ( 4.0 litre straight six ) I have had a few timming chains fall off through wear but because they were fitted to OHV or SV engines no damaged resulted. Except I had a chain break bunch up around the crankshaft sprocket and burst the timing cover ( A series BMC) But the timimg cover was cheap and easily replaced. The chain was about £3 new. Longer stoke engines have much more room above the piston for the valves so even when the timming is totally out the valves do not hit anything. Worst is a short stoke deisel with an OHC driven by a cam belt if the belt goes then the valves will destroy the engine even on the starter motor. Last time I saw this happen the engine was scrap. Incidently never run a cam belt for any lenght of time with the cover removed because the cover sometimes will keep a belt on when the on of the guide rollers or water pump fails-- at least it gives a chance of turning the engine off due to noise of the belt hitting the cover rather than bang and complete silence. If I hear any noises coming from a cam belt area then I insist that it is checked. I was alarmed to see the introduction of plastic guide rollers on some cars. Call me old fashioned but I like to see solid conventional engineering in this department.

Hi Pat, Forget soluble oil as a coolant additive for following reasons: 1. It rots rubber hoses as mentioned by Bob. 2. It is highly susceptible to micro-biological organisms which feed on the soluble oil compounds - if you spill contaminated soluble oil solution on your skin, you will get a very nasty case of dermatitis which you will not forget for a long time. |

Thanks for the info. Regarding the ingredients one was called lubrifoss Lm or Ml may have spelt it wrong! Something called alco and an antifoam agent. |
