I have been noticing that I am losing anti freeze from somewhere. I have to refill the reservoir once or twice every couple of weeks. I put down a sheet under th truck to see if there is a leak, but there wasn't any leaking out....


Thought I may have a cracked head, but no symptoms of that. The truck was running a little on the upp end of the temp gauge the other day, and now has been running fine the last two days.

Any ideas?

Thanks.

Leaky head gasket?

 

i had the same issue with my 94 4.9 it turned out to be the waterpump ' i had a good look under the truck and saw it leaking right under the fan. this is where the pump is ' its attached to the fan just go for a short drive then park it and hop out and see if your leaking from it or not
