About a week after I bought this car, I found that the coolant level was low. I topped it up, and kept an eye on it. The car seemed to lose about 3 quarters of a litre over a few days. It didn't obviously leak, overheat or show anything else wrong. So I assumed that this was the early signs of cylinder head gasket failure . I bought some K-Seal, added it to the cooling system, and idled the engine till it warmed up. I eventually did another 18 or 19,000 miles in the Peugeot. There was no further coolant loss.

"I purchased peugeot 306 with head away on ebay and then the K seal and because it worked I bought some for my toyota celica and the head gasket can wait to be fitted. "
"Dear Sir or Madam. I bought K-Seal to fix my heater matrix which had a bad leak. It stopped within two minutes which was four weeks ago. I've found the Kalimex very good as my heater matrix has remained bone dry. Job was a 1994 [Peugeot] 405 diesel. Thanking you very much."
"I USED K SEAL IN A PEUGOUT 306 DIESEL AND IT WORKED! I USED IT ON THE M53 MOTORWAY JUCT 9."
