Pro – Diagnostics and Engine Management

OPTIMUM enginePRESTONE COOLANT CON 1L GB performance is of vital importance for mechanics so the market leader in aftermarket products, Holts, is offering advice on how to be prepared this summer with Prestone.
The effects coolant can have on engine temperature and subsequently a vehicle’s emissions of NOx is particularly significant and carefully monitoring coolant levels will make a significant improvement to the engine’s performance.
Prestone Coolant/Antifreeze is compatible with all makes and models of car, inclusive of their metals and component parts, and mixes with any colour of coolant/antifreeze already in the system – a perfect ‘no fuss’ solution for mechanics.


The coolant not only protects aluminium and all other engine parts for up to five years, or 150,000 miles, but also ensures a car engine performs in even the most extreme conditions, from -37 to 129 degrees celsius.


Jonathan Fry, Owner of Jonathan Fry Automotive, said: “I can recommend Prestone coolant to any customer knowing it will meet their vehicle’s specifications and will mix with whatever coolant is already in the cooling system.”


Developed by the experts behind the number one coolant in the US for use by professional mechanics, Prestone Head Gasket and Engine Block Repair is an advanced sealer which can be used at home to fix leaks anywhere in the cooling system.


The product is guaranteed for any car and any coolant/antifreeze and provides a professional permanent seal in minutes.
There is no clogging or damaging effect on the engine and the anti corrosion formula also protects against further leaks.
Aside from permanently repairing leaks, Prestone Head Gasket and Engine Block Repair can also be used to fix engine blocks, cylinder heads, freeze plugs, water pump gaskets, radiators, heater cores and hoses – making it an engine essential.


The product is quick to use – simply pour and fix, for a permanent repair. Ross Kavanagh, Professional Mechanic at Sean Kavanagh’s Garage, said: “I would recommend Prestone Head Gasket and Engine Block Repair for anyone who is looking for an easy solution to leaks etc.
“I found it very easy to use and effective to fix the problem.” Prestone Coolant/Antifreeze can be purchased as a concentrate or ready-to-use product.
