Outer Limits 4x4 Board

just wondering if someone can help me out.

i have a 91 model 4.2 turbo diesel and im wondering if there is a difference between the petrol and diesel radiators. the car had an RB30 in it and was changed to the TD42 turbo diesel. it's over heating and im just wondering if it's running the wrong radiator and wat the difference between the two radiators is.

From memory, they are different with the TD one being bigger.

any idea how many cores the diesel one's have

one of the biggest differaces is that the petrol radiator outlets are on the opposite side to the diesel

The factory one had two cores & did the job nicely (no turbo though).

I put a 3 core in & have only ever had it change position on the guage when abient is over 38 on long hills at 100 +.

Mind you it was with the air on and the guage moved from just under half to just over half.

Never moves, even when towing big loads, any other time & we have some big hills around here.

the 3.0 petrols have the same outlets as diesel but dont have a pipe on
the filler neck for the bleeder hose that comes off the top of the thermostat housing of the diesel to hook up 2 which helps purge air from the system

This is the same radiator I'm running in mine and it keeps my turboed V8 cool.

i think i'll pull it out and get it cleaned and pressure tested. the car was running fine until last week so it must be something small(fingers crossed). if thats no good i may have to look at a 3 core

are the diesel and turbo diesel different sizes ??

according to repco. petrol and diesel patrols run the same radiator.

Be careful of these radiators. I have one & the bastard has split the tank twice within the 2 year warranty period.

Their warranty is very conditional, the radiator has to be sent away for testing and examnination (to SA) if there is any problems.

When mine split I just had it repaired by a local mob & they said they see them all the time with these sorts of problems.

Last time it started to leak form the core I just filled it with silver seal, I will replace it next time.

They just seem tp split at all the joining areas, its a real PITA.

They are also not just a straight replacement either, I had to modify my cowling so it would fit again.

Earlier models are copper/brass and the later models are ali with plastic tanks. I have one of each eg an 89 GQ and a 96 GQ.

all the copper tanked rads are the same, only the out lets change. rb,td,tb identical. after market 3 core.....

i do a copper tanked f100 radiator 4 core, bolts straight in, you will have to cut some of the inner guard away . i have done these in v8,turbo diesel, turbo petrol where they could not be keeped cool. they are not cheap but work perfectly $700 - $800

wat year model f100's do they come off?
