Do you know your turbo boost pressure?

Any smoke while driving?

 

i dont know boost pressure no smoke while driving just at start up normal burst at start up. going to get guages this week pyro trans temp and boost ,can i go cheep on these guages found on ebay 200 sumthin w/ pillar. im on unemployment and low on funds. still woried about new radiator ,the 2 row in sted of 3 makes for alot wider/taller port .more fluid volume more time needed to cool. maybe over thinkin it.

 

I am trying to remember, but wasn't there a rubber piece filling between the rad support and the front grill shell?

You need that. If that's open, put a piece of cardboard in there and tape it. Without it, the air goes under the truck and not through the rad.

Sounds like you did everything. . .

Just for the heck or it, is this an automatic? Bad auto Trans can cause them to run hot too. Check the trans lines after a drive.

What I didn't see was how fast it creaps up. I know the hill you are talking about. . I was just through there a couple of months ago.

How is it when idling?

 

my 95 is an auto . i asume check lines for excessive heat. ill be installing pyro boost and trans temp guages when they arrive my fluid looks new and shifting is flawless.bottom of hill temp is 190 195 by 1.5 mi im at last line before red i keep speed down to 50 -55 if i floor it i probly wont make it to the top with out hitting red.im not comfortable running this far into my guage havent loaded trailer up yet and want to pull my jet skis behind trailer.idles smooth at 6-700 rpm after 3 years of stalling read idle adjustment yesterday took 10 min . a real pain but done

 

What I meant was does it heat up while idling?

You don't have your spare on the front do you. . . .

 

should i take the front tire off but i paid allot of cash 4 that1/4 in plate to mount it . not at all. after running 10 min.got in cab to hold rpms up 5 -10 min of that and up to 180 deg. and stays . today i tryed to rap and clamp apiece of rubber were fan clutch slips at bolt maybe clutch is not giving 100% ,took the hill and noticed sum improvment but not much, checked my hi tec set up when i got bak to find fan slipping. so cant eliminate clutch not giving 100% again it is new.

 

Had me going for a second

I forget the front of those. Lord knows I hade 4 1st gen diesels.

There's a guy on another forum I know that has one of that vintage. He may be able to shed some light on it. . . I know he's done a ton of work on it. I'll PM you on how to contact him.

It's actually a Mopar car forum, but very similar to DTR in experience and information. Brian is pretty sharp and the only guy I know who might be able to help you. I think he may have had an issue like this with his.

 

So it just started doing this? Or has it always been this way?

Coolant sensors don't typically go bad but can't rule it out.

I say check your exhaust temps. If something is clogged in your exhaust causing your egt's to go up, that'll do it.

 

im prety sure its always been like this but never towed heavy loads .four years ago pulled a32 ft deck boat out of bolder city marina. its about 3mi into boulder start hill from a stop 115deg. that day and had to turn air off got to the red , pre #6 fuel plate .on my guages whats the diff. on egt and pyro if i rember rite pyro is pre exaust?

 

He's not have a dramatic loss of power if the exhaust were clogged.

But the Cat can go. . . Not needed. It's not doing anything but keeping some tree hugger happy

 

id stick a temp gun or aftermarket temp gauge on it to compare it w factory gauge. your fan clutch will always slip jus a lil bit. even when "locked" it will technically slip a few rpms. is your temp light coming on as well. if i recall correctly the pcm has a different sensor than the gauge and if you can find some one who can connect a scan tool to the truck and see what the PCM is seeing that wud be another thing to try

 

yea cj thanks for a new direction. been tryin to figure on a guage set, orderd glow shift but im canceling becouse of sum good advice and comon sence says i need a quality guage.auto meter maybe they are still in my $ range?

 

If it's that hot, you should be able to smell it

I think that site is fixed. ..again. . .

 

Autometer is excellent. They stand behind their products and fix or replace a gauge if broken.
