Anyone ever used this?
 

A coolant additive ment to help aid radiator efficiency. Being on the Rimmers site would have thought it would be 'safe'.

sounds a bit hopeful i have to say, cutting warm up times in half? i doubt ud notice any difference in it! but never heard of it mate

Yer id never heard of it just browsing their site and it was in the clearance section. Thought being on their site prob wouldnt be like some of these 'dodgy' additives

dunno mate think its a bit optimistic, these additives are never as good as they say they are, question would be why wouldnt the manufactures put this in the cars if it reduces warm up times ect, by 50%, just imagine it would do nothing much really possibly clean the system or somthing but if is it worth it? nah doubt it!

yer wouldnt expect the stated results. My worry if it cleans the system where does all the crap go?!! Not going to bother with it not a fan of putting anything in the system that wasnt there when it left the factory,

yeah id just keep the oat in it:) is yer car still overheating or have ye sorted that now?:)

Nope still steaming tried a different cap but wonder if the tread on the bottle is slightly warn so gonna get rimmers to put a tank on to the order of the new cap as well to rule that out. Its a weird one though!!

thermostat in the right way round? ehm take it fans are kicking in okay, temp sensor and wiring okay, put some block tester in it?

Thermostats in right, got up to 3/4 on the temp gauge today then it dropped back to the 1/2 mark so guessing the fans had kicked in. It was block tested and came back clear.

Its just the steam from the cap/tank so new cap and tank and then see what happens. The old tank had split so little worried about why that had gone, pressure build up in the system?!

possible yeah, the caps are quite bad for failing on them, know some of the guys at work replace them as part of thier yearly service, the new tanks about £10 - 15 if i remember right id be cleaning all the connectors on the temp sensors as well so what was done to it when did it start over heating, is the waterpump working right ect
