So yeah, my coolant is disappearing from my resivoir. I looked at my coolant in the Radiator, and it looks A ok. I looked at the oil on my dipstick, and it is A ok, no milky appearance at all. I poped the oil cap off, looked at the bottom and it was A ok. looked inside at the valve springs and stuff and it looks A ok. Should I be concerned about my head/ head gasket? I have had a rough idle at a certain RPM, but its been very minor. What do you guys think?

 

Do you have the engine skirt thingy that covers the underside of the motor? That will hid leaks from you. Look around the passanger side of the radiator for discoloration from the coolant leaking around the side tank-core seam. The under side of the water pump will leak when its going bad and not alway leave a puddle on the ground

Also white exhaust smoke means your burning coolant, blue means your burning oil. rule of thumb.

 

I recently replaced water pump after it blew bearings and pitched my belt into the fan on I5. Also T-stat is new. I have not seen any smoke out of tail pipe and Oil looks great. I think Ive just scared myself about head hgasket, hopefully its just a small hose leak. I have not been to keen on looking under the jeep lately, but I reall seeing some drops under the front end recently, and I did the finger test to see if it was oil, it was water/ coolant. No skirt, its a 92', that thing peaced out years ago via erosion

 

You need to perform a comprehensive search for a leak. Best to get it up on a hoist or at least ramps to do so.

Do your checking with the engine hot and cooling system fully pressurized. Use a good light.

Performing a "cooling system pressure test" can also be a great step in isolating an issue here. This tool can be rented from many big box parts stores.

Good luck and post back what you find!

 

Yeah, just consulted a friend. he has one and Ill perform this text next weekend. working for the forest service last summer, our chevy 6 pack burned 4 quarts of oil a week. we always joked that it never needed an oil change, just a new filter every once in a while.
thats how Im ffeling about my coolant :-) ... but I want this issue G O N E gone!

 

Its always a good idea to replace hoses when you do waterpumps. When one goes the others are quick to follow

 

for sure, Ive done some within the past ~5 years, heater core, upper... etc. Just started my new summer internship, so maybe with the first check ill get the whole shebang of new hoses
