Morning Folks,
I currently own a 1992 ex-MOD hard-top 90 2.5na, which has recently developed a bit of an overcooling problemo!
No matter how far or hard I drive it, the temperature gauge never gets above a quarter of the way, the heaters blow cold and it's generally bit sluggish (yes, more than usual!). FYI the gauge used to sit firmly in the middle no matter what the weather!
I've bought 2 genuine thermostats, the original spec one and also the higher temp one. Both of which I have tested in water with an IR thermometer and confirmed working properly. Yet when fitted, I still have the same issue. I've even had the IR gun on the engine and that is only getting up to 66c!
Yesterday I took the truck to a local indy who has replaced the stat again and can't see anything else wrong with it.
Finally, I've also replaced the cable from the temp sensor to the gauge and crimped some nice shiny ends on it, just to make sure that it wasn't shorting anywhere.
Any advice is greatly appreciated!
Cheers,
Tom
