Overheating!!! Be careful this summer!

Overheating!!! Be careful this summer!

Did you know that your engine can be overheating with you even knowing it! Yes, that's potentially true – and can have dire consequences. Here's why, for a coolant sensor to be accurate, it must have coolant flowing past it. If you have a coolant leak or complete loss of coolant, your coolant temperature sensor and therefore gauge will not react properly. In the winter there are often some simple signs that your coolant is low, particularly you often will notice that your heater is not blowing hot air. But come summer, that little warning of no heat from your vents goes unnoticed, pair that with running the A/C which pumps even more heat into the engine, and you can have catastrophic engine failure come up faster than you realize. Yes, some vehicle have coolant level sensors to warn you of low coolant level, but they don't always work reliably. And with the abundance of plastic engine (and cooling system) components in use today, some age and time cou ... read more

LR3 & RRS heater core issues

LR3 & RRS heater core issues

We here at JC’s British & 4×4 have started to see a trend regarding heating issues on LR3s and Range Rover Sports. This trend has been an issue with heater core blockage and uneven heat coming from the vents. Oddly as the blockage increases it does not evenly reduce the heater core temps from all vents, but lowers the Driver’s side temps dramatically while the passenger side appears to be unaffected. This problem leads many shops and technicians toward replacing the control servos, which in most cases solves nothing. To replace the heater core is a very large and time consuming job, the entire dash assembly has to be removed. We have had some success power flushing the heater core with our Gates Power Flush cooling tool. This is a process we would highly recommend before a noticeable clog/heating issue is present, perhaps ... read more

Only time will tell how this will affect the marquee, but they did get backing from both Rover & Jaguar workers unions, and have said they will hold true to tradition. In Feb 08, I’ve brought back my apprentice (Drew Wheeler) from my 1st year of running the shop, I had been trying to get him back on occasion over the last year or so, and finally he agreed to leave Corvettes Only to rejoin us here. Tech Tips With most vehicles, running the recommended octane gas will maximize performance and gas mileage. This is due to multiple engine sensors and programming that can make use of that octane rating.
