At low speed there is less ram air, and greater reliance on the fan/rad. I had a blocked rad, which caused low speed overheats, dumped coolant periodically too. As soon as I changed the rad, problem solved, but not before i'd needlessly replaced the t stat and viscous fan
No. Massive difference. Heads: first time call it a weekend to pull off, order all bits during the week and the next weekend to put together. Engine out is a long weekend just to get it out and a bit of a saga to be honest. Even finding a suitable engine crane. The rear seal can be done by removing the gearbox which is a mini saga and has its own dangers - the torque converter dropping forward so the oil pump drive disengage. Repair, sell and buy a diesel....
