#1 of 8 Envoy Losing Coolant very slowly 4.2L by melmccune Jan 17, 2008 (3:00 am)
Envoy Losing Coolant very slowly I have a 2003 Xl. It has been losing about 1/2 gallon of coolant every month. I have looked every where for leaks with no luck. Any suggestions??? Replies to this message: burdawg (Feb 10, 2008 11:51 am) reg11 (May 29, 2008 5:55 pm)

The best thing to do is have the cooling system tested under pressure to confirm.
#3 of 8 Ticking Noise by paco42754 May 03, 2008 (7:54 pm)
I have a F150 Sport 4.2L V6. I have a ticking noise that I can't find. It's driving me nuts. Sounds like it could be in the exhaust but not sure. Is this common in the 4.2? And how can it be fixed? Replies to this message: steve_ (May 03, 2008 8:07 pm)

Replying to: melmccune (Jan 17, 2008 3:00 am) Any success with finding the coolant leak? I am having the same issue with my 2002 Envoy 4.2 L engine. HAd it in the shop twice, cannot seem to locate where coolant is going. Loosing 2 litres or more between oil change?? I know there were cylinder sleeve crack issues with these engines when they first came out- hope it's not that! Anyone else having similar problem or had it fixed. Thanks, Reg

Replying to: reg11 (May 29, 2008 7:06 pm) My baby sister is having the same problem with her 2007 Envoy 4.2.L engine. The radiater has been pressure tested and ok. Compresson tested ok. No sign of fluid on driveway and no discoloring of the tail pipe. Has anyone out there found a answer to this problem? If so what is the answer.

Have a 2007 Envoy that loses antifreeze at a abnormal rate. The radiater has been pressure tested and ok. Compression tested and ok. No sign of fluid in driveway and no discoloring of the tail pipe. No increase in oil level, which would indicate it leaked into the block . Has anyone out there found a answer to this problem? If so what is the answer?
