I am a widow with children and kept my husbands pickup. Sentimental reasons. I have to get this on the road so I can get my 84 year old dad before he tries to drive here. I know its weird for a woman to work on vehicles but I have never had much choice. My husband was an ace mechanic and I didn't do this now I MUST. If you have input I would appreciate it.

When I changed my cooling system out I just left the cap off with the engine running and kept squeezing the upper and lower rad hoses for about 30 minutes as the coolant circulated. At least that's all the book said to do, didn't know these were self bleeding systems.

I've had the same issue with my 4.6L. Lost heat, Overheated, coolant blows out the reservoir, temp comes back down. Changed the t-stat, flushed the system, refill, and changed the pressure cap on the reservoir. 2+ months and no overheating yet, still air in the system I can hear the occasional "gurgling" in the heater-core.

try replacing radiator cap. had almost same problem with mine, new cap for 5.00 was the fix..

that got the air out of mine and of course allowed the system to pressurize and work properly. if the cap dont get the air out you need to put a "t" connector with a bleeder cap in your heater hose. it is located on passenger side of your intake about 1 and 1/2 inches round. the heater hoses are the highest part of the cooling system,this is why the air is so difficult to get out of these systems, the t connector costs about 2.00 at a parts store.

This thread is prehistoric.

Hopefully they still arent having this problem haha

They may not be, but others are. It's still relevant, especially as these trucks age and develop more of the same problems.

I'm going to try the t-valve on the heater core hose. I've had the same problem. I hear gurgling when i accelerate. It overheats about once a week and i know it is about to overheat when the heat begins to get cold. I've had it tested twice for bad headgaskets and changed the t-stat. if this doesn't work i'm thinking i will change the waterpump.

might be the water pump. the blades wear out and while it may be working, doesnt create enough flow. it could also be a coolant sensor gone bad.

Is that a common spot for air to get in?

No whats common is no one knows the proper bleeding procedure. The coolant resivior has to be high than the heater core to properly bleed the system.
