    Can't remember which one I got for a friend, about $15 off eBay, but I think the significant thing was that it had a little toggle switch. You can look at the Forscan forums for recommendations with at least pictures of what your looking for. Bluetooth to tablet may be an option also, but I haven't done that.

    It's nice to see the little bar graph on a laptop plotting different sensor readouts; the only way to do that in non-OBD cars before 96 is with a breakout box for the EEC-IV, or a TwEECer RT - $450.

    Similar situation with a "transistor tester", there's about 20 different clones from China, you've got to look at the pictures and gamble a little bit.

    As has been mentioned in other threads, the OBDLink MX is $80 -ish, and you can use various apps on your smartphone as well. Torque Lite is free, you can choose most of the channels in OBD-II to display at your leisure, and as long as you have a phone or tablet the module is much cheaper than the plug in gauges mentioned above. Though not as permanent an installation of course.

    Was the car over heating (boiling)? Did you have to add more water?

    If the temp jumps rapidly its its possible that you have air in the system, also pointing to a seal problem. If the system isn't completely air tight you can experience overheating issues.

    Definitely a bad cap can cause the system not be pressurize, or lose pressure lowering the boiling point of water quickly and allowing it to escape. Unless you keep your engine bay extremely clean there should be signs of the water vapors escaping. If not look elsewhere. This is also a good time to have a second method of measuring your temps using the ODB-II.

    I barely have 300K between the two of my SHO's! Seeing that many miles is impressive, to say the least!

    I got it off nextech classifieds for 400. He thought it had blown head gasket because the upper hose was pressureized

    These cars are known to accumulate crap in the cooling fins of the radiator. I would look at that, a new cap, and maybe old hoses collapsing.

    Right, a recent lesson for me. 20+ year old hoses are more a problem than mileage. My recent experience left me walking 30 minutes out on my way home from a trip. It was that one hose I didn't replace...

    This is the one from the oil cooler to the engine block. Thankfully I was in a populated area where an Autozone was about a mile from the gas station I made it to. Since I didn't have tools I had to buy all those along with the hose, making this one mistake more expensive than preventative maintenance. Not to mention the burns on my arms from the exhaust and water pumps. But once fixed and filled up she was raring to go again!

    That's an odd 9/16" ID hose. These cars are full of odd sizes... Might have been able to go down to 1/2", but with the room I had I couldn't get it on, so had to go up a size.

    Exactly the same I replaced on mine some weeks ago. :) She starts to inflates and let escaping some coolant by one clamp (you can go under the car, more precisely under oil cooler, and watch for a leak from a clamp too).

    I suppose the next step is just what we are seeing here... (It seems the hottest hose will broke first...?)

    Its very encouraging to see others owners with car passed the 300k ! Don't give up !

    Ah, I am never going to catch up to that. :) Only use the car occasionally now and am at, IIRC, 207,000. I should go look. But once it is no longer a daily driver, the miles stop piling up really fast.
