sorry, 99

 

Sounds like it could be a hose or your Heater Control Valve. Check the area to the rear of the engine bay on the passenger side and try to determine exactly where the leak came from. Coolant leaks are very rarely a one-and-done deal, and you'll want to nip this problem early.

 

yeah I know it'll come back if ignored and I aint about to do that.

 

did 99's have HCV's. I thought I read somewhere that those were deleted. prob wrong on that. if they did have an HCV, will that involve a dash teardown. please no........

 

You're covered. The HCV would be in the engine bay, but your '99 doesn't have one. I'd start with the coolant lines where they meet the firewall. They may be splitting, or you may be missing a hose clamp.

 

Thanks, clown. I'll get into it.
Might was well do that system flush I've been meaning to do while I'm at it.

 

No problem, bud. And now would definitely be a good time. Consider replacing your heater core while you're tearing into the system. It may not be necessary, but it may be worth it for winter depending on your budget and climate

 

May I ask why you have to replace it? If it stopped working, you should take it apart and clean the armature and check the brushes. That may fix it.

Now, if you broke it off with a rock, you may need a new one. I'd try the Whitney first.

 

My Jeep is named Derek because i literally couldnt turn it left the day after i bought it

 

 

Well to give an update, my wife's uncle repairs starters so I'm taking it off Saturday and taking it to him to look at. Depending in the damage it's gonna cost, I'll get it repaired or replaced with a new one.

 

I always rebuild my own starters, unless it's one that is really fried or tore up, which is a trip to the auto parts place. I do aircraft starters anyway, so the auto stuff just fits in...

 

How much horse power does a stock inline 6 engine put out??

 

4.0L performance Mods.....and Stats..
4.0L Engine revisions *********

'87-'90: 177hp at 4500rpm, 224lbft at 2400rpm, redline 5000rpm
The '87-'90 engines had Renix electronic multipoint fuel injection, electronic ignition, a 52mm throttle body, and an inefficient "low port" cylinder head similar to the old 4.2L/258. They have a water temp port in the back of the head. (Use a '91-'95 HO head for a head swap to replace these most easily.)

'91-'95: 190hp at 4750rpm, 225lbft at 3950rpm, redline 5250rpm
In 1991 engines received Chrysler sequential MPFI, a larger 60mm throttle body, revised intake and exhaust manifolds, and a more efficient high port cylinder head. As a result, these engines produced 13hp more than their predecessors and gained the "High Output" designation.

'96-'99: 190hp at 4600rpm, 225lbft at 3000rpm, redline 5300rpm
In 1996 engines received noise, vibration, and harshness fixes. The blocks were stiffened with extra ribbing, a main bearing brace was added, and lighter cast aluminium pistons were introduced to improve efficiency and reduce cold start piston slap. Engines also received revised camshaft timing for more low rev torque. Heads are similar except that they have no water temp port. (The OBD II system drives the guages and, only requires one port, these can be drilled and tapped for the sender used in earlier models if you're doing a head swap.)

'99.5-'01: 193hp at 4600rpm, 231lbft at 3000rpm, redline 5300rpm
In 2000 a distributorless coil-on-plug ignition system was installed, intake and exhaust manifolds were revised, and a more efficient water pump was included. These heads are quite different. They have smaller exhaust ports and, mounting bosses for the coil pack used with the distributorless ignition. There are different accessory mounting hole locations on these as well.

 

they revised the intake manifold design in 99 but then revised the exhaust manifold design in 2000
