hello, I think I have a leak even though I have no trace under the car or in the v .
: o I’m afraid it’s the water pump ( it was replaced 6 months ago but I had seen traces of dried coolant under the place where the water pump is mounted). In fact, I smell coolant when I get out of the vehicle (hot engine). Unfortunately, it’s not in my skills. good evening. |

i hope a new gasket was used. also there are i believe some of the mounting screws that are drilled straight through into the water jacket they will need to have sealant put on the threads. i hope it was a new pump fitted because they nearly always leek when they have been disturbed whilst fitting a new cambelt. when the belts are changed its recomended to renew all items. otherwise you could be back in there again with a leeking water pump 6 months later ...

The reason that people replace the pump is because to do so in future would involve repeating the cambelt renewal exercise. Unfortunately this can backfire as some aftermarket pumps have subsequently leaked. Possible reasons for this are poor quality parts and/or careless installation. Simon

thankyou simon.i fully understand that the waterpump does not need to be disturbed or removed. what i was trying to suggest was that the release of belt pressure and re-applied was in itself a "disturbing " action on the bearings / seals within the pump itself. this may of course have been an assumption by other members rather than being a case of a pump that was ready for change anyway. if the belts were in need of change then the pump was about ready for change in any case. did the o.p say somewhere in the thread that the pump had been changed along with the belts recently ? if that indeed is in truth correct and the job has been done then as you say either poor quality parts or workmanship seems the likely culprit. ... regards stefan.....

I agree that it is best to remove the intake to fit the new thermostat rather than use the "Keyhole" method That gives you the opportunity to change the intake/head gaskets. On one of my V6s one of these developed a leak that would drain the system in minutes. If one develops a small leak the thermostat could be blamed.
When fitting a new pump I found that some of the mounting holes on the pump had to be filed for proper alignment. I also fitted Viton seals to the cap on the expansion tank to replace the original flattened seals. There has been no comment on the Kaiser metal thermostat housing. Opinions?
