New to the forum, and would appreciate any advice. I bought a second hand 1995 Sportrak ELXi with a good amount of MOT a few months ago. Delighted. The vehicle was exceptionally clean and drove well. Fitted towbar and dual electrics intending to tow 14ft 2 berth caravan over to home in Czech Republic. Noticed slight overheating just a few miles after setting off going down M5. Vehicle overheated totally going up hill onto Cotswolds near Air Balloon roundabout. Caravan not overloaded and well within manufacturer's limit. Cap blew off radiator bottle just at top of hill. Cooled down in layby and returned home, stopping several times. When back from CZ a couple of months later vehicle failed MOT on emissions, but did not overheat unless at high speed on motorway (no caravan attached). Carbon monoxide content after 2nd fast idle very high. Garage observed catalytic converter and lambda sensor both fairly new which squares with receipts supplied with vehicle.
Any advice or suggestions gratefully received. All I get from friends is "Get rid, cut your losses" but I really do like this vehicle and I would like to keep it if I can get the overheating problem solved and the emissions in control.
Could it be that the two problems are linked?
Grateful thanks. Mark.
