coolant leak


  1. Disappearing coolant

    Truck info: 91 Ranger XLT 4x4 5 speed 2.9L v6 originally I had this issue and found it was leaking into my oil so I replaced the head gaskets and had the heads checked out they are okay and not cracked before reinstall. All new hardware ie gaskets headbolts oil(change 2x to flush the engine)...
  2. Coolant Pressure Test Adapter

    I am trying to hunt down a small coolant leak in my '94 4.0. I went to rent one of those pressure testers to try and see if I could hunt it down that way, but the problem was none of the adapters fit the radiator. I have searched all over online and am having a hard time finding an adapter that...
  3. Coolant Loss

    I noticed coolant escaping through my radiator cap recently. I was told it could be my head gasket or a bad radiator cap. It has 214k miles and the last engine overhaul was done at around 195k miles which included a complete gasket exchange, head resurfacing, and tune up. Since then, I have...
  4. 3.0 Lower Radiator Hose Replacement Help

    Hey Guys, I need to replace the lower radiator hose on my 2002 Ranger Edge 3.0, and was hoping to get some advice/input on the easiest way to remove and install the smaller branch of the lower radiator hose that goes to the front of the engine (to the water pump(?)), since that area is really...
  5. Third heater core in 2 years

    A few days ago I smelled antifreeze and saw lots of vapor coming from the vents. I have a hard time believing that the problem is yet another heater core, especially since there is no puddle on the floor. It's easy enough to replace that damn thing but I would really like to find the root cause...
  6. 3.0 Coolant Leak Lower Radiator Hose

    Hey Guys, I seem to have a coolant leak coming from the connection of my lower radiator hose (engine side) on my 2002 Ranger Edge 3.0L. I'm looking to replace the factory spring-type clamp with a worm-type clamp, and was wondering if it would cause any problems or hose damage if I just leave...

    Coolant loss - but NOT heads!

    Hi guys, I've been dealing with a major coolant loss in my 96 xlt for about a month now. I bought the truck off of craigslist about four months ago and have been upgrading stuff since then, but am at a loss as to what's going on. Recently, I put in new gaskets on the lower manifold, valve...

    heater control valve leaking, P0171 code

    OK, strap in, because this may be a long one.... This 4.0L OHV (166K miles) will throw a P0171 code during a regular, in town drive, but will never throw this code during highway driving. Also worth mentioning, the MPG is steadily going down the crapper. She used to throw both a P0171 and P0174...
  9. Coolant Leak

    I just purchased a 1990 Ranger 4x4 with 2.9 liter V6. I have a coolant leak that is spraying on the engine side of the air conditioning compressor and wetting the hood directly above the ac compressor. Any thoughts on where the leak is most likely coming from. I can't seem to see the leak...
