I have A 95 F150 302 with 164,xxx miles.

I have to fill the overflow bottle about once every 2 weeks because it's empty.

Its not leaking because there is no puddles under the truck but its lower on power than it should be and when I shut the truck off it smells like coolant.

There isn't coolant mixed into the oil and there is not oil mixed into the radiator.

Is this a headgasket, cracked head, cracked block, etc.?

 

there is a chance that you have a coolant leak in your radiator when its at pressure, have the system pressure tested.

 

What tools would I need to do a pressure test, what does the tool look like, and/or where could I get it done at?

 

most shops can do it, i just have a shop do it since i would never use to tool myself lol. but most parts stores will sell the tool also.

 

I will pull a plug tomorrow and see if there is any coolant down in the cylinders since that's a free check.
Lol

 

you can also pull the radiator cap then start the truck, if there are bubbles its a blown headgakset. after the truck warms up the fluid should go up and down slowly.

 

Thank you.

I'm hoping if it is the head gasket I caught it early enough since oil and coolant aren't mixing and ill just have to replace the gaskets

 

Just because you don't have drips on the ground does not mean you don't have a leak, crawl under and look while it's running, that big *** fan on the front can blow a leak all over and the heat of the engine / exhaust can make it burn up / evaporate (hence the smell). Does your exhaust have any white smoke? Does the exhaust smell like coolant?
