Another Sunday query... I had to replace my heater core as the original had a leak into the cab. Pulled the heating / ventilation box put to do it. Not a huge task and ended up totally refurbing the box and flaps and whatnot Thing is, I can run the Jeep for miles but the heater never seems to...

Hi all I have a 1989 2.5l 4 cyl. Can anyone tell me what revs they are happy going to in 2nd, 3rd, 4th and 5th gears please? Silly question I guess - had it three years - but I do tend to play it very safe to preserve the engine. Recently I did a speed test with a 'sat nav true mph' app to see...

Hi all Will a TJ lightbar that sits around and slightly in front of the windshield, fit on a YJ windshield frame? It's the chrome one that has the four light plates and is bolted in to the bottom outside of the windshield frame in a TJ. One for sale over here but I don't know if it will sit on...

Hi all I'd like to give my JP Jeep a bit more of a 'wider wheeled' look. I know, I know it-s a Jeep not a lowered Honda but I quite like the look of a little more tyre out the arch. Any advice on safe sizes or effects it might have on handling or stress. I'll never off road it afain and stick...

Hi all Been having fun in my rejuvenated 2.5l YJ (busted EFI is out, shiny new Carb is in) and putting down some nice mileage and she is doing great so far. I have noted that she sometimes feels 'notchy' when changing gear. Clutch is smooth as butter. No clangs or scrapes or grinding etc. Just...

Here's one for you sound hounds! I have a Jurassic Park Jeep and I have two small hidden car speakers for playing the score and sound effects and dialogue from JP93. I want to add a hidden external passive sub or bass speaker to give it that extra and much needed low down 'grunt!'...

Hi all. I had my EFi taken out of my 1989 2.5 4cyl and a Weber lookalike Carb put it. After about two months of fiddling around and tweaking to what I thought was perfection I now have this problem... I drive 110 miles at approx 60mph for about 2.5 hours. Drives beautifully, better than ever...

Hi all, pop quiz! What the blazes is this thing called and can i buy the see thru plastic screen bit? Mine is crazed over and almost pointless. Thanks all!

Hi all, my throttle cable has about 1.5 to 2 inches of play. i e in the engine bay I can push down, or tug the cable almost two inches before it pulls the linkage on the carb to make the engine rev. It also means the gas pedal is floppy. Its always been that way but now I have a carb installed...

Hi all, been a long time due to illness and the YJ being at a mechanics or 5 months but me and the Jeep are back on the road. So here is my query as Im new to carbs. I had the EFI taken out and a Weber Carb put in and she drives again. Great news. Drove her 130 miles home, no issue, then a 20...

Hi, is it possible to buy the very front sloped panels over the front wheels? I had the Eurospec signals on mine (UK jeep) and deleted them to build the Jurassic Jeep but despite some sanding and filling I can't get the factory smooth finish on them. Not sure what they are actually called but...

Hi all. Tested the compression on my 4 cylinder 2.5 and these are the results: Cyl1 - 129 Cyl 2 - 125 Cyl3 - 130 Cyl4- 145 Tried it a few times, they all report the same. Is this good or bad? Still trying, after 8 months and some £2000 later, to even get it to start and run properly. Cranks...

Hi all. OK so I've just emptied my tank to desert dryness. Then refilled with 3 gallons or so. Gauge is hardly moving from the bump stop, as in just about touching the bottom of the red marker. Surely should be showing at least near rhe quarter way mark? Any suggestions?

Is there a special way to mount a TPS? I ask as the bolt holes allow for jigging about and I wondered if there is a 'perfect' position you need to adust it to before screwing it in tightly? If so, what do I need to do and why? Thanks!

Hi, I recall then previously owner saying he replaced the waterpump but had to get another one as it was pumping in the wrong direction? I think I may need a new pump as my temp gauge goes from 0 to 260 in about 4 minutes of firing up and the hoses to and from the engine get super hot but the...

I notice that my TPS has what appear to be variable positioning slots to screw the TPS to the throttle body. Is there a special way to screw it on so it works properly with the throttle body? I.e does it need jigging clockwise/ anticlockwise a mm or so or will any position do and just screw it...

Hi, Im going to try replacing the three infamous capacitors from my original 1989 ECM. Do you know the three capacitors I need to buy please? Looks like 2 x ITT 4004 and 1 x ST140 written on them? Thanks all.

Does anyone know where I can get hold of a parts list or a wiring diagram for a 1989 2.5l ECU/ECM please? I'm trying to buy the three blue capacitors that have burned out on my board, one of which links to pin 3 on the connector. Many thanks!

Well, I'm back. And so is my Jeep. After three months at three different mechanics I got my Jeep back yesterday. Still not running. So here is the latest for you wizards to fathom out.... On two occasions where she was trailered to mechanics, upon unloading, she started just fine, like nothing...

Hi all, just wondering how hard it is to take a 2.5l out and replace with another 2.5l? Thinking of doing this with my still kaput 89r. Tried everything under the sun and three mechanics and she still wont run anywhere near smooth. Thanks!
