Blowing coolant out the cap

[teamheeler87]

This morning I started my truck and let it warm up for about 10 min. Got in it and drove to the office. Didn't get on it hard just kinda putted around and cruised. When I got to the office I noticed the driver side wheel well was wet and then a stream of coolant steamed down from underneath the hood. I looked and it came from my reservoir cap. Which I had just replaced because of a similar thing happening. What's going on?

How full do you run your coolant level?

 

[teamheeler87]

The full line. And that's with it running.

Sounds like you might need a head gasket is your truck studded or do u have a egr delete

 

[teamheeler87]

It's got the egr delete from sinister. But unfortunately no head studs.

might be time to replace head gaskets bud.

Does your coolant smell like diesel fuel or do u c a rainbow in the coolant bottle

 

[teamheeler87]

Well okay then. Head studs and gaskets it is. One more question. Some people say use the food head gasket some day use aftermarket. What should I get?

 

[teamheeler87]

Doesn't smell like diesel or have a Rainbow. Smells normal

Any white smoke at start up that you c

 

[teamheeler87]

No white smoke either. Even the temperature of the coolant and oil run within 8 to 10 degrees of each other

let her warm up and remove slowly the cap and see if you can spot bubbles in the reservoir. My bet is it's headgasket time for you.

 

[teamheeler87]

No white smoke either. The temp of the coolant and oil stay within 8 to 10 degrees if each other.

 

[teamheeler87]

Yeah im thinking so to. I'm ordering the parts right now.

Ford head gaskets only.

[yeehaw]

when you say full line, is that the min or max line??

 

[Magnum PD]

Cometic gaskets don't work?

 

[teamheeler87]

I filled the resevoir with coolant while the truck was running and hot to the max line.

 

[SaNnDnSurF]

Ford gaskets only I learned the hard way with the black onyx

 

[Captainharley6.0]

The min line is the new max line, if you fill it to the max with tunes its gonna burp coolant. Is your heater blowing cold air at idle then warm air under acceleration?
If cold air most likely gaskets which is my deal, if not and you just over filled tank and faulty cap i would replace cap for 15$ and fill to min line and try thst before a horny mechanic starts tearing things apart for 69$ hr
